Woodland Sauna and Cold Plunge on the Isle of Arran
Tucked away beside a stream in our private woodland near Blackwaterfoot, our wood-fired sauna and natural cold plunge are the perfect way to unwind after a day exploring Arran.
Whether you've been hiking, cycling or simply enjoying the outdoors, there's nothing quite like warming up in the sauna before braving a refreshing cold dip.
Our sauna and cold plunge are exclusively for guests staying at Hamilton Cottages and are not open to the public. Private one-hour sessions are included at no extra charge with every cottage stay. Just another reason to choose our well-equipped self-catering cottages on the Isle of Arran.

SwimwearA towel to sit on (we recommend a microfibre sports towel)Drinking water (no glass or metal bottles)Advised - crocs / water shoes / flip flops (especially if using the cold plunge pool)Advised - a changing robe
Yes please. Sitting on a towel helps protect the sauna benches from stains and keeps things hygienic for everyone.We recommend bringing a microfibre sports towel for the sauna, so you can save the cottage towels for your shower afterwards. Trust us, a fresh dry towel is much nicer than trying to dry off with the warm, damp one you’ve just been sitting on!
Yes!
The sauna is a great place for families to relax together and children aged 4 and above can use the sauna however it is imperative that a responsible adult observes how a child’s body is responding to the high temperatures and is aware of signs of discomfort such as dizziness, headaches and feeling too hot. As a very rough guide, our children aged 4 and 6 enjoy the sauna with us at about 50oC for 5-10 minute sessions and splash up to their knees in the plunge pool between sessions.
Ratio of Adults to children under 12 is 1:1.
Anyone under 18 years old must be accompanied by a responsible adult.
Children should never be left unattended.
The stove is very hot and would cause severe burns if touched or fallen against.
As a rule, the younger the child, the more vigilant the adult needs to be.
This is really up to you but most people enjoy it between 75-85oC.
The temperature can be controlled by adding more logs or opening the door or window to cool it down. You'll also notice its significantly cooler if you sit on the lower bench and nearer the door.
Adding water and increasing the humidity will make it feel a lot warmer.
For children we'd suggest having it a bit cooler.
Up to 6 people can use the sauna at a time.
Please do not exceed this or you will be liable for any damage or injury caused.
It will take 45-60 mins to light the sauna and get it up to temperature.

Listen to your body and take breaks as soon as you feel you need to. Most people enjoy the rounds of 5-15 minutes in the heat with breaks of 5-10 minutes to cool down in between.
There is a timer on the wall you can use to keep track of how long you have been in.
You can fully submerge in the plunge pool or just stand outside, its up to you!!
However we do recommend you try at least a few splashes from the plunge pool to get the skin tingling and enjoy the full experience!
The wooden dam at the end of the plunge pool can be raised or lowered or removed completely to change the level of the water in the pool but it will never get more than about 3ft deep to keep it as safe as we can for all users.
We advise wearing water shoes or croc type shoes in the plunge pool as there can be sharp stones on the bottom.
Please ask children not to throw stones/sticks etc into the plunge pool as we've spent about a year trying to get the stones out of it and get it to a usable depth!!!
Use of the plunge pool in any weather conditions is at your own risk.
EVENING USE
For your safety, please be aware that the plunge pool is a natural feature and not floodlit. While low-level lighting is provided, conditions may be dark or uneven. Use of the pool, particularly after dark, is entirely at your own risk.

No, our sauna is self service so you'll need to light it and operate it yourself. This means you get the full experience and can decide what temperature you like!
As our sauna is 'self service' we do ask that you look after it and leave it as you found it so we can continue to keep a relaxed vibe with it!

Between 5–9pm (aka sauna rush hour!), when more than one cottage is occupied, each cottage may book only one slot. Any additional bookings may be cancelled.Outside of that, we like to keep the booking system relaxed and flexible — we just ask that everyone uses it considerately.
This varies dramatically throughout the year but there is a floating thermometer hanging outside the sauna so you can check it for yourself if you are interested!
