About
Take a little time for yourself at Hot Rocks Sauna Castlerock, an outdoor sauna and cold plunge experience beside the Railway Sleeper Hostel at Castlerock's historic railway station.
Set in a coastal village on Northern Ireland's Causeway Coast, Hot Rocks offers a welcoming space to slow down, warm up and enjoy good company. Whether you live nearby, are staying for the weekend or are exploring the coast, it's an easy way to add something different to your day.
At the heart of the experience is a wood fired barrel sauna, with space for up to six people per session. Step inside, settle into the warmth and let the pace of the day ease off. Outside, their whiskey barrel cold plunges offer a refreshing contrast for those who want to try them, while the outdoor seating area gives you somewhere to take a breather between rounds.
Each booking gives you an hour to enjoy the facilities at your own pace. Spend time in the sauna, cool down outside and choose whether to take a dip before warming up again. There's no pressure to brave the cold or keep up with anyone else, the experience is yours to enjoy.
Come with a partner, catch up with friends or book a place on your own. The small, shared setting makes Hot Rocks as much about conversation and connection as it is about heat and cold. Both first time visitors and regular sauna users are welcome.
Make it part of a day in Castlerock, combining your visit with a beach walk, a coffee in the village or a stay at the Railway Sleeper Hostel next door. Their railway station location also makes arriving by train a natural option for visitors planning a day out along the coast.
Visit the official website to check current session times, prices and availability, and book your place before travelling. We look forward to welcoming you to Hot Rocks.
