The Tuwa hot springs, in India's Gujarat state, offer silica-rich water at 41°C in a still-wild setting. A simple open-air pool allows for a natural bathing experience, away from typical tourist infrastructure.
Insider tip — Tuwa is one of western India's lesser-known geothermal curiosities, where silica-laden water vents through Deccan-related volcanic geology on the Gujarat plains. The springs are regarded as sacred and draw pilgrims for ritual bathing. Visit during cooler winter months (November–February) when the ambient heat makes soaking genuinely refreshing and the surrounding countryside is at its most welcoming.
