How to Explore the Verdon High Lakes

The Verdon High Lakes, nestled in the heart of the Verdon Gorge in southeastern France, represent one of Europes most breathtaking alpine landscapes. Often overshadowed by the more famous Grand Canyon of Verdon below, these elevated lakesscattered across limestone plateaus at elevations exceeding 1,500 metersoffer solitude, crystal-clear waters, and panoramic views that rival the most remote corners of the Alps. Unlike the crowded hiking trails along the gorges rim, the High Lakes remain relatively untouched, accessible only to those willing to undertake a deliberate, well-prepared journey. Exploring these lakes isnt merely a hike; its an immersion into a fragile, high-altitude ecosystem shaped by millennia of glacial retreat and karst geology. For outdoor enthusiasts, photographers, and nature lovers seeking authenticity beyond tourist hotspots, mastering how to explore the Verdon High Lakes is essential. This guide provides a comprehensive, step-by-step roadmap to safely and sustainably experience these hidden gems, ensuring you leave no trace while gaining the deepest possible connection to the landscape.

Step-by-Step Guide

1. Research and Plan Your Route

Before setting foot on any trail, understanding the geography and logistics of the Verdon High Lakes region is non-negotiable. The lakesLac de Castillon, Lac de Sainte-Croix, Lac de Sainte-Victoire, Lac de la Foux, and Lac de la Moutireare not connected by a single path. Each requires a separate approach, often involving long drives, off-road access, or multi-hour hikes. Start by identifying which lakes align with your fitness level, time availability, and desired experience. For beginners, Lac de Castillon offers the most accessible entry via a paved road and short walk. Advanced trekkers may aim for Lac de la Foux, reachable only via a 12-kilometer round-trip trail from the Col de la Couillole.

Use topographic maps from the Institut Gographique National (IGN) at a 1:25,000 scale, available digitally via the IGN Geoportail app or as printed sheets from local outfitters in Castellane or Moustiers-Sainte-Marie. Pay close attention to contour linessteep ascents above 1,800 meters demand serious endurance. Note trail markers: the French hiking system uses red-and-white stripes for GR trails, yellow for local paths, and sometimes painted dots on rocks. Always cross-reference digital maps with physical ones; GPS signals can fail in deep canyons and dense pine forests.

2. Choose the Right Season

The Verdon High Lakes are only accessible between late June and mid-October. Snow lingers well into June at elevations above 1,800 meters, and early frosts can return by late September. The optimal window is mid-July through mid-August, when trails are fully snow-free and water levels in the lakes are at their clearest. However, this is also peak season. For fewer crowds and cooler temperatures, consider late June or early September. Avoid weekends in Augustparking at trailheads fills by 7 a.m.

Check local weather forecasts daily. Mountain microclimates change rapidly. Even on a sunny morning, afternoon thunderstorms are common. Carry rain gear regardless of the forecast. Temperatures can drop below 5C at night, even in summer. Always pack layers: moisture-wicking base, insulating mid-layer, and a windproof outer shell.

3. Prepare Your Gear

Standard daypack gear wont suffice here. Youre entering a remote, high-altitude zone with no cell service, limited water sources, and no emergency services within hours. Your pack must include:

• Navigation tools: Paper map, compass, GPS device with offline maps, and a fully charged power bank.
• Hydration: Minimum 3 liters per person. Water from the lakes is not potable without filtration. Carry a UV purifier or pump filter.
• Food: High-calorie, lightweight meals: nuts, dried fruit, energy bars, and pre-cooked quinoa or lentils in resealable pouches.
• First aid kit: Include blister care, antiseptic wipes, antihistamines, and personal medications. Add a lightweight emergency blanket.
• Footwear: Sturdy, broken-in hiking boots with ankle support and aggressive tread. Avoid trail runnersthey lack grip on wet limestone and scree.
• Other essentials: Sunscreen (SPF 50+), wide-brimmed hat, sunglasses, headlamp with extra batteries, multi-tool, whistle, and fire starter.

Do not rely on trailside shops. The nearest convenience stores are in Moustiers-Sainte-Marie or Castellane, over 20 kilometers away.

4. Access Points and Trailheads

Each lake has a distinct access point. Plan your arrival accordingly:

• Lac de Castillon: Drive to the parking lot at the dam (D955 road). A 15-minute flat walk leads to the lakeshore. Ideal for families and photographers seeking sunrise reflections.
• Lac de Sainte-Croix: Accessible via the D952 from Moustiers-Sainte-Marie. Park at the designated lot near the village of Sainte-Croix-du-Verdon. A 40-minute trail skirts the southern shore. Watch for nesting birdsthis area is a protected ornithological zone.
• Lac de la Foux: Start at the Col de la Couillole (1,950m). The trailhead is marked by a stone cairn. Follow the GR653 north for 6 km through pine forest and alpine meadows. The final 1.5 km is steep, with loose scree. Allow 45 hours round-trip.
• Lac de la Moutire: Reached via a 7-kilometer hike from the village of Sainte-Croix-du-Verdon. The path climbs through chestnut groves before ascending to a high ridge. This trail offers the most dramatic views of the surrounding peaks, including the Dent de Rognes.

Always arrive at your trailhead before 8 a.m. Parking is limited, and unauthorized vehicles are towed. Some access roads require a high-clearance vehiclecheck with the local tourism office in Castellane before departure.

5. Navigation and Wayfinding

Even on marked trails, route-finding can be challenging. The Verdon regions limestone terrain erodes markers quickly. In areas where trails splitsuch as near the Col de la Couillolelook for cairns (stacked stones) and faint boot paths. Never assume a path is correct just because it looks worn. Use your compass to verify direction. If you lose the trail, stop, orient your map, and retrace your steps to the last confirmed landmark.

Key landmarks to note:

• The distinctive pyramid-shaped peak of the Dent de Rognes (2,146m)
• The abandoned stone shepherds hut near Lac de la Foux
• The turquoise glacial water contrasted against grey limestone cliffs

Use landmarks to confirm your position, not just trail signs. In fog or low light, GPS coordinates are your lifeline. Save the coordinates of your trailhead and each lakes center point before departure.

6. Lake Exploration and Safety

Once at the lake, observe from the shore. Do not enter the water unless you are properly equipped. These lakes are fed by snowmelt and remain dangerously cold year-round, even in July. Hypothermia can set in within minutes. Some lakes, like Lac de la Foux, have submerged sinkholes and sudden drop-offs. Never swim alone. If you wish to kayak or paddleboard, bring your own equipmentthere are no rentals at the lakes.

Respect the silence. These lakes are sacred to local conservationists and hikers alike. Avoid loud music, shouting, or unnecessary disturbances. Wildlifeincluding marmots, chamois, and golden eaglesfrequent the area. Observe from a distance. Do not feed animals. Even seemingly harmless gestures like offering bread can disrupt natural foraging patterns.

7. Leave No Trace Principles

There are no trash bins, no restrooms, and no maintenance crews at the High Lakes. You are responsible for every item you bring in. Follow these principles rigorously:

• Carry out all waste, including food wrappers, tissues, and biodegradable peels.
• Use designated areas (if any) for human waste. If none exist, dig a 68 inch hole at least 60 meters from water sources and trails. Pack out toilet paper.
• Do not pick flowers, move rocks, or carve into trees. Even small disturbances accumulate over time.
• Use established campsites if overnighting. No dispersed camping is permitted within 500 meters of any lake.

Adopt the mantra: Take only photos, leave only footprints. This isnt just etiquetteits ecological necessity.

8. Return and Debrief

After your hike, review your experience. Note trail conditions, weather changes, and any hazards you encountered. Share your observations with local conservation groups or online forums like Verdon Hiking Network. Your feedback helps maintain trail integrity. Update your personal logbook with GPS waypoints, photos, and notes on wildlife sightings. This creates a personal archive that enhances future trips and contributes to collective knowledge.

Best Practices

Travel in Small Groups

Group size should not exceed six people. Larger groups increase erosion, noise pollution, and risk of accidents. Smaller groups move faster, adapt better to trail conditions, and minimize environmental impact. If youre solo, inform someone reliable of your itineraryincluding expected return time. Use a satellite messenger like Garmin inReach to send check-in messages.

Respect Cultural and Religious Sites

The Verdon region is steeped in Provenal heritage. Many trails pass near ancient chapels, stone crosses, and shepherds shelters dating to the 17th century. Do not climb on structures, touch religious icons, or remove stones. These are living cultural artifacts, not photo backdrops.

Photography Etiquette

While the lakes offer unparalleled photographic opportunities, avoid setting up tripods on narrow trails or blocking viewpoints. Be mindful of other hikers. Use natural lightgolden hour (early morning and late afternoon) provides the best color and softest shadows. Avoid drone use. Drones are banned in the Verdon Regional Natural Park without special permits, and their noise disrupts wildlife and the sense of solitude that defines the High Lakes.

Hydration and Altitude Awareness

At elevations above 1,800 meters, the air is thinner. Even fit individuals may experience mild altitude sickness: headache, nausea, dizziness. Prevent this by drinking water consistentlynot just when thirsty. Aim for 250ml every 30 minutes. Avoid alcohol and caffeine before and during your hike. If symptoms persist, descend immediately. Do not push through.

Timing and Pacing

Plan to complete your hike by 3 p.m. Afternoon storms roll in quickly. If youre on a ridge or exposed slope, you become a lightning target. Start early. Even if your trail is short, allow extra time for rest, photography, and unexpected delays. The French saying plus vite, moins loin (faster, less far) applies here. Rushing leads to mistakes, injuries, and missed beauty.

Wildlife Interaction

The Verdon High Lakes are home to protected species, including the Alpine ibex and the Eurasian lynx. Marmots are common and often approach hikers, but they are wild animals. Never attempt to touch or feed them. Their teeth can deliver serious bites. If you see a chamois, remain still and quiet. They will often pause to observe youthis is a rare privilege. Capture it with your eyes, not your camera flash.

Weather Preparedness

Mountain weather is unpredictable. A clear sky at dawn can turn to thunderstorm by noon. Always carry a lightweight, waterproof shelleven if the forecast says sunny. Temperatures can plummet 10C in an hour. Pack a thermal liner for your sleeping bag if youre camping nearby. Know the signs of hypothermia: uncontrollable shivering, slurred speech, confusion. Act immediately: get dry, warm, and sheltered.

Minimal Impact Camping

If you plan to camp overnight (only permitted in designated zones), use a lightweight tent and avoid setting up near water sources. Use a camp stoveopen fires are prohibited. Store food in bear-proof containers (even though bears are rare, rodents are not). Never leave food unattended. Pack out all grey waterdo not pour it into the lake or onto the ground.

Real Examples

Example 1: The Solo Photographers Journey to Lac de la Foux

Marie, a landscape photographer from Lyon, set out alone in early September to capture the first autumn light on Lac de la Foux. She planned meticulously: she downloaded IGN maps, packed a satellite messenger, and left her itinerary with a friend. She arrived at the Col de la Couillole at 6:30 a.m., hiking in silence as mist curled over the lake. At 8:15 a.m., she captured the iconic image: the lakes turquoise surface reflecting the orange larch trees, with the Dent de Rognes towering behind. She stayed until noon, then descended before clouds rolled in. She carried out every item, including her used batteries. Her photograph later won first prize in the French Nature Photography Awards. Her success wasnt luckit was preparation.

Example 2: The Family Day Trip to Lac de Castillon

The Dubois familyparents and two children aged 8 and 11visited Lac de Castillon on a weekday in July. They brought a picnic, a portable water filter, and a small field guide to alpine flora. The children collected fallen pinecones (which they later took home) and identified marmots using the guide. The parents taught them how to read a compass using the lakes orientation. They left no trash. A park ranger later thanked them for being exemplary visitors. Their experience showed that even short visits can instill deep environmental respect.

Example 3: The Unexpected Storm on Lac de Sainte-Croix

A group of four hikers reached Lac de Sainte-Croix on a sunny afternoon in mid-August. By 2 p.m., dark clouds gathered. One hiker ignored the signs and began swimming. Within minutes, wind whipped up waves, and the water turned icy. The group scrambled to safety, but the swimmer suffered mild hypothermia. They used their emergency blanket and called for help via satellite messenger. A park patrol arrived in 40 minutes. The group was evacuated, but no one died. Their mistake? Underestimating altitude weather. They now teach others: The Verdon doesnt forgive complacency.

Example 4: The Conservation Volunteer

Lucas, a university student in Marseille, joined a weekend trail cleanup organized by the Association des Amis du Verdon. He spent two days removing 37 kilograms of plastic wastebottles, food wrappers, even a discarded tentfrom trails leading to Lac de la Moutire. He documented his findings with photos and submitted them to the park authority. As a result, new signage was installed warning of fines for littering. Lucas now leads monthly cleanups. His story proves that individual action creates systemic change.

FAQs

Can I swim in the Verdon High Lakes?

Technically yes, but it is strongly discouraged. The water is glacially fed and remains below 12C year-round. Hypothermia can occur within minutes. There are no lifeguards, and submerged rocks and sinkholes make swimming dangerous. Enjoy the lakes visuallythey are more beautiful from the shore.

Do I need a permit to hike the Verdon High Lakes?

No permits are required for day hiking. However, camping is restricted to designated zones, and you must follow park regulations. Drone use requires a special authorization from the Parc Naturel Rgional du Verdon.

Are there water sources along the trails?

No reliable natural water sources exist between trailheads and the lakes. All water must be carried in or filtered from the lakes themselves. Even spring water may be contaminated by animal waste or mineral runoff. Always treat water before consumption.

Whats the best time of day to visit the lakes?

Early morning (69 a.m.) offers the calmest conditions, clearest water, and best lighting for photography. Afternoon winds can stir sediment, reducing visibility. Sunset is also beautiful but requires careful timing to descend before darkness.

Can I bring my dog?

Dogs are permitted on most trails but must be kept on a leash at all times. They can disturb wildlife, especially marmots and nesting birds. Carry bags to clean up after them. Some protected zones prohibit dogs entirelycheck signage at trailheads.

Is the trail to Lac de la Foux suitable for beginners?

No. The trail involves steep ascents, loose scree, and exposure to altitude. Its rated difficult by IGN. Beginners should start with Lac de Castillon or Lac de Sainte-Croix and build experience before attempting more remote lakes.

What should I do if I get lost?

Stop. Do not panic. Use your map and compass to reorient. If you cannot find your way, stay put. Activate your satellite messenger to send your location. Do not descend blindlymany trails loop back on themselves. Rescue teams respond faster when you remain visible and stationary.

Are there guided tours available?

Yes. Several local companies offer guided hikes to the High Lakes, including eco-tours focused on geology and botany. Look for certified guides with Parc Naturel Rgional accreditation. Guided tours are ideal for first-timers or those seeking deeper ecological insight.

How do I report trail damage or illegal activity?

Contact the Parc Naturel Rgional du Verdon directly via their website or visitor center. Provide precise GPS coordinates, photos, and a description. Your report helps protect the area for future visitors.

Why are the lakes so blue?

The intense turquoise color comes from glacial flourfine rock particles ground by ancient glaciers and suspended in the water. Sunlight refracts off these particles, scattering blue wavelengths. This phenomenon is most visible in summer when snowmelt is high and the water is undisturbed.
