Bains de Saillon, Valais – Family thermal center and spa

A warm water break at the foot of the vines

Between Sion and Martigny, the Bains de Saillon are a sure bet for a relaxing outing with children. The atmosphere is gentle, the water is warm, and it's easy to move from indoors to outdoors, even in the middle of winter. It's the ideal place when looking for a simple, serene, and friendly activity, without having to plan too far in advance.

What your children will love

The thermal pools are vast and invite quiet play. The thermal river, with its gentle current, always has its little effect: you let yourself be carried away, you laugh, you do it again. The youngest enjoy the shallow areas and dedicated wading pools, while the older ones appreciate the outdoor spaces and, depending on the season, aquatic activities and small adapted slides. In winter, swimming outside in the steam is a magical and sensory experience that children won't forget.

What to expect on site

• Warm, mineral water, pleasant for everyone.
• Indoor and outdoor pools accessible all year round.
• Quiet areas to relax and a pace that remains family-friendly.
• Spa/sauna access reserved for adults and older teens (generally from 16 years old), perfect for taking turns if you come as a couple.

In terms of atmosphere, this is a rather calm and rejuvenating activity. Children move around, swim a bit, test weightlessness in the water, but without the pressure of a sports pool.

Answers to common questions

• Age: recommended from 2 years old to fully enjoy the shallow areas (always under adult supervision). Younger babies may be sensitive to heat; consult your pediatrician and limit time in hot water.
• Duration: plan for 2 to 3 hours, with a hydration break and a small snack.
• Reservation and rates: entry is paid; online reservation is highly recommended on weekends and during holidays. Family rates and discounts may be available, check before you go.
• Accessibility: the site is designed to welcome families, with changing rooms, showers, and stroller access on the main paths. Outdoor areas may include slopes; take your time.
• Public transport: regular service from Sion and Martigny, stop "Saillon, Les Bains" a few minutes' walk away.
• What to bring: swimsuits, towels, non-slip sandals, water bottles, swim diapers for little ones, and sunscreen in summer. Arm bands or flotation vests reassure less confident children.
