Alpine swimming at the natural pool of Marécottes (Valais)

A Swim That Changes Everything

Above Martigny, in Les Marécottes, you discover a pool like no other. Here, the water is natural, nestled in the rock, with a view that gives the impression of swimming in the heart of the Alps. The atmosphere is peaceful, family-friendly, and you quickly feel that you are experiencing a moment apart, away from the noise and chlorinated slides.

What Your Kids Will Love

Children love climbing on the flat rocks, jumping from the edge (where allowed), and feeling the refreshing water that awakens them. The experience is sensory: the texture of the stone warmed by the sun, the contrast of the clear water, the mountain air. It’s playful, but also very natural: you observe, you listen, you take your time.

What to Expect On-Site

• A rather calm and nature-oriented activity, with a sporty touch for those who swim or try jumps supervised by parents.
• Ideal duration: 2 to 3 hours, or even half a day if you combine it with a walk in the village or a break at the nearby restaurant.
• Ages: from 3-4 years with armbands and close supervision; perfect for older kids and teens comfortable in cold water.
• Season: summer opening only. The water is refreshing (alpine!), best enjoyed in warm and sunny weather.
• Reservation: generally not needed. Entry is paid daily; combined offers with the nearby site may exist depending on the season.
• Stroller accessibility: the surroundings are partly rocky and sloped; it's better to plan for a baby carrier for the little ones.
• Public transport: stop "Les Marécottes" (Mont-Blanc Express) followed by a short uphill walk. By car, parking is indicated in the village/near the site.
• Safety: natural pool, variable depth, rocky edges. Official supervision varies by period; keep children within reach and equip them properly.

What This Outing Brings to Children

• Motor skills and confidence: learning to enter the water, manage the coolness, and move on uneven terrain.
• Sense of observation: noticing the rock, the transparency of the water, the alpine landscape.
• Gradual autonomy: setting simple rules (swimming area, no running on rocks) helps them gain responsibility.

Before You Go

Prepare swimsuits, towels, water sandals (very useful on the stone), sunscreen, a cap, and a light fleece for after swimming. A water bottle and a small snack make a difference. If you come with a child sensitive to the cold, slip in a bathrobe or a large microfiber towel.

Parents' Tips

• Arrive late in the morning to enjoy the warmth on the rocks and avoid crowds.
• Bring armbands or a float, even for good swimmers at first.
• Choose a fixed point on the shore as a "family base" so that children can spot you.
• Test the water gently: first the feet, then up to the knees, to get used to the coolness.
• Check the opening conditions on the same day: weather and temperatures can influence the schedule.
