Hike and Wild Swim in the French Pyrenees

Wild swimming in the French Pyrenees is all about refreshing dips in rivers and glacial lakes after your hikes, the perfect way to cool off and unwind in stunning surroundings. Your guide will lead you to each swim spot, where you’ll usually have time to relax, enjoy a picnic and take a dip if you fancy. Swimming is entirely optional and always intended as a short, revitalizing cool-down, rather than a guided open-water swim where you’re expected to cover a distance.

Your guide will remain on shore during swims, and these spots do not have lifeguards or other supervision, so please don’t swim out of your depth or beyond your comfort level. Water temperatures in summer are cold, often 50–59°F in the high lakes, so always test the water before entering. As these are natural locations with limited facilities, we recommend bringing a large towel or robe for changing, and neoprene shoes for rocky entries.

Refuges are simple but welcoming. Expect shared dormitories (usually mixed gender) with bunks, mattresses, and blankets. Bring a sleeping bag liner. Facilities are basic, with shared bathrooms and communal dining rooms where meals are served.

You'll be led by one qualified International Mountain Leader, who is also your swim guide. No additional support crew is required for this trip.

Your guide is experienced at managing mountain conditions and will adapt the itinerary if needed for weather, safety, or group well-being.

The signal is patchy in the higher valleys and around the refuges. Wi-Fi is not available in the huts; enjoy the digital detox.

Yes, your larger bag can be safely stored at the hotel in Luz Saint Sauveur while you are on the mini trek.

Tap water is safe to drink in Luz Saint Sauveur. In the mountains, you can refill from refuges and some streams. We recommend bringing purification tablets or a filter for untreated water.

From June to September, expect warm, sunny days in the valleys, with average highs in the low to mid-70s°F. Temperatures are cooler at altitude and can drop close to freezing at night, especially in the mountain refuges. Weather in the Pyrenees can change quickly, so be prepared for sun, rain, and cloud in a single day — good layers and waterproofs are essential.

June: Early summer may still bring snow at higher elevations and the lakes are at their coldest. Trails are quieter.

July–August: The warmest months, with valley temperatures in the mid-70s°F and long daylight hours. Popular with hikers and families.

September: Cooler, crisp days and fewer crowds. Evenings can be chilly but swimming is still possible.

Lake and river swims are always refreshing — expect water temperatures around 50–59°F in high lakes, and slightly warmer in lower rivers.
