Thomas's hot bath

Located on the seafront in Bouillante, Thomas’s Bath is a unique natural site where visitors can enjoy a small pool of hot water (capacity: 10 people) fed by a volcanic spring that gushes forth at over 70°C, then mixes with seawater to create a bathing temperature of around 35–45°C, depending on the tide.  
The hot water, naturally rich in minerals, is particularly appreciated at the end of the day for a moment of relaxation facing the sea. The site is also renowned for its peaceful atmosphere at sunset, when the light softens and the setting becomes even more pleasant.

🌿 Why we love this spot

• natural pool of hot volcanic water
• easy (but watch out for rocks) and quick access (short path: 3-minute walk from the parking lot)
• unique, relaxing seaside experience
• pleasant, intimate setting without tourist infrastructure
• beautiful spot at sunset

♨️ Things to know

The temperature depends heavily on the tide and the water level in the pool:

• Too much water in the pool → the water gets cooler (temperature close to that of the sea). Cold water is therefore often linked to a strong inflow of seawater.
• Little water in the pool → the water can get very hot, even too hot. Swimming may not be possible at certain times

⚠️ Respect the site
The basin is a fragile natural area: please follow the rules posted on the sign near the basin.

🚗 Parking 
Parking is available nearby, but spaces are limited during busy times, especially in the late afternoon and on weekends.

💡 BAM Tip
Plan your visit for late afternoon or evening to enjoy pleasantly warm water and a calmer atmosphere—perfect for relaxing by the sea.
