The Jurassic Sauna is a small wood-fired beach sauna at Branscombe Mouth, ten minutes' walk from Hole Mill. It opened in recent years and has quickly become one of the most-talked-about new things on this stretch of the East Devon coast — a properly hot Finnish-style sauna in a simple wooden hut on the back of the pebble beach, run by a small local team. Walk down from Hole Mill, do a session, swim in the sea (or run into it screaming), walk back. This is the honest review.

What it is

The Jurassic Sauna is a single-hut wood-fired sauna on Branscombe Mouth — set on the National Trust beach about 100 metres back from the high water mark. The hut is timber-built, with a single bench room inside, a wood-fired stove, and a small changing area. It is heated to a proper Finnish temperature (75-90°C) using local seasoned wood. There is no electricity at the site; everything is run on log fires and clean water carried in.

The model is straightforward. You book a slot online for a specific time. You arrive ten minutes before, get in, sweat for 12-15 minutes, run down to the sea for a cold plunge, come back, repeat as desired for the length of your booking. Most sessions are 45 minutes to an hour.

The whole thing is run by a small local team and is genuinely loved by the people who run it. It is not a corporate spa experience — it is closer to a Finnish summer-house sauna in atmosphere.

How it actually feels

We have done it. It is excellent. Three things stand out:

1. The contrast with the sea is the point. The standard Finnish cycle is hot-cold-hot-cold. Here the cold is the English Channel — about 14°C in summer, 8-10°C in winter, sometimes colder. The combination is genuinely euphoric for ten or fifteen minutes afterwards. People emerge talking faster than they went in.

2. The location is the difference. Lots of places have wood-fired saunas. Very few have a wood-fired sauna 100 metres from a deep, swimmable, properly cold sea. The Jurassic Sauna is right at the back of Branscombe Mouth — you can see the sea from the door of the hut. It takes 30 seconds to get from sweating to swimming.

3. The atmosphere is unfussy. Bring your own towel, your own swimwear, your own water. There is no spa music, no scented oils, no mood lighting. Just a hot stove, a wooden bench, and the sound of the sea outside.

When to go

The Jurassic Sauna runs year-round, but the experience is genuinely better in autumn, winter and early spring than in mid-summer. The colder the sea, the better the contrast with the sauna. Our favourite time is November to March — the sauna is hottest, the sea is most invigorating, and the beach is empty.

In summer the sea is warmer and the contrast is less dramatic. Sessions in July and August are still excellent, but the magic is slightly diluted.

Time of day matters too. Sunrise and sunset sessions are the best — fewer people on the beach, golden light, and a properly atmospheric setting. Mid-afternoon weekday sessions in summer are the busiest; quieter slots are early morning or after dark.

Practical information

Address: Branscombe Beach (Branscombe Mouth), at the back of the National Trust car park. Look for the small wooden hut about 100 metres north of the Sea Shanty café.

Distance from Hole Mill: half a mile, 10-12 minutes' walk.

Booking: essential. Slots can be booked online — search "Jurassic Sauna Branscombe" for the current booking platform. Sessions sell out at weekends in winter; weekday slots usually open up.

Cost: typically £20-£30 per person for a 45-60 minute session, with discounts for groups. Prices vary; check the booking platform for current rates.

Group sizes: the hut takes about 6 people comfortably; larger groups can book the whole hut for a private session.

Duration: standard sessions are 45-60 minutes, including time to change.

Towels and water: bring your own. Bring also: swimwear, flip-flops or beach shoes (for the walk to the sea), warm clothes for afterwards, and a flask of hot tea (the post-sauna walk back is much improved with a hot drink in your hand).

Parking: at the National Trust car park at Branscombe Mouth (small fee). The sauna hut is a 60-second walk from the car park.

What to bring

A practical packing list:

  • Swimsuit or trunks (worn under a robe or towel for the sauna)
  • Two large towels (one for the sauna bench, one to dry off)
  • Flip-flops or beach shoes
  • A wooly hat (warm head, cold body — useful for the walk back)
  • Warm post-sauna clothes
  • A flask of hot tea
  • A small dry-bag for keeping clothes dry on the beach

Tips from people who have done it

  • Drink water before, during and after. A 90°C sauna dehydrates fast.
  • Don't eat a big meal beforehand — leave at least 90 minutes after a heavy meal.
  • Ease into the cold sea. Walking in to your knees and standing is a perfectly valid first plunge. You don't have to do a full immersion straight away.
  • Stay in the cold for less than a minute. The point is not endurance; the point is the contrast. 30 seconds in the sea is enough.
  • Repeat the cycle three times. One sauna-cold cycle is interesting. Three is properly transformative.
  • Avoid alcohol immediately before or after. Combined with high heat and cold water it is a bad idea.

Health and safety

  • Don't sauna alone if you have heart problems or high blood pressure without consulting your doctor first.
  • Don't sauna pregnant without medical advice.
  • The sea has tides. Branscombe Mouth is generally safe for cold-water swimming but check tide times — the beach is much smaller at high tide and there are stronger currents in the channel between the pebble bars.
  • Children under 12 are usually not allowed in the sauna for safety reasons. Check with the operator.

Combining with the rest of the day

The most enjoyable way to do it:

  • 3.30 pm: walk down from Hole Mill to Branscombe Mouth (10-15 minutes).
  • 4 pm: sauna session (1 hour).
  • 5 pm: dry off, change, walk back up to Hole Mill via the Sea Shanty café for a hot drink.
  • 6 pm: Hole Mill's wood-fired hot tub for an hour (a perfect post-sauna activity).
  • 7.30 pm: dinner at home or at The Mason's Arms in the village.

That is, genuinely, one of the best winter Saturdays you can have in this corner of England.

Why it is worth doing

The Jurassic Sauna is one of those places where the simple version of an idea is done with enough care that it becomes special. There is nothing flashy about it — a wooden hut, a wood-fire, a thermometer, the sea. But the combination is extraordinary, and the location, on the National Trust beach below Hole Mill, is unbeatable. We send guests there roughly half of all the weeks we host, and have not yet had one come back unconvinced.

The Jurassic Sauna is half a mile from Hole Mill and one of the most distinctive things to do on a stay here, especially in winter. Check our availability for your dates.
