Cave Swimming 2025

I’ll often think that we’ve found everything west Cornwall has to offer and then…she’ll throw up a surprise. This cave was a wonderful little addition to an already packed menu. I’m going to look to start doing cave swims with head torches. An exciting little addition. We’ll still do a decent swim but add a little stop on the way. We’ll simply pack some head torches and dish them out mid-swim…or you can go without…

The swim/cave featured is in west Cornwall. There are also suitable caves at Kynance Cove.

Annual Lizard Peninsula Swimming Holiday

One of our highlights every year is the Lizard Peninsula swimming holiday. We always hold it on the first weekend of September. The water is still warm and the crowds have thinned out. We’ve held this holiday for the last four years and each one has been absolutely stunning!

This year we really had to work. We had a southwest swell that rules out the west coast and easterly winds…so our experience really came into play, during the planning for this trip. Despite challenging conditions, we put on 5 delightful swims, in flat and enjoyable conditions.

Swim 1 - Kennack Sands following a route north, along the coastline, using the cliffs for shelter. Clear water, plenty of marine life and a great swim to start everyone off.

Swim 2 - Coverack, another nice and sheltered swim. We swam up and checked out the harbour before again, swimming north and keeping out of the wind. From there we took advantage of the location and popped into Roskilly’s. Epic pizza and ice cream…

Swim 3 - Durgan on the Helford river. Stunning morning swim, in pan flat conditions. Swimming from Durgan over to Trebah, then back across to Durgan to Grebe Beach. Beautiful scenery and weather. From there we visited the very unique and beautiful Potager Gardens for lunch.

Swim 4 - Parbean Beach. Takes some effort to get to but we had a very nice swim towards the mouth of the estuary / end of the headland and back. A new route for us.

Swim 5 - Church Cove / Gunwalloe. A proper sea swim…as we had snuck in a few river routes. Great morning for it and as it was swim 5, we picked a route that allowed a half way exit.

Safe to say that everyone had a fantastic weekend, including the staff! Bring on 2024.

The Devil's Chimney Cave Swim

We’re fairly certain this cave doesn’t have an official name, so we’ve named it the ‘Devil’s Chimney’. There’s a small, dark opening that could easily be missed and has been at least once by us! From the outside it looks very unimpressive, simply a small dark opening under a large rock. When you swim into the cave it’s quite narrow, it’s dull and not particularly impressive. Once you get into the cave, that’s where the magic. There’s what we like to describe as a chimney that allows light to flood in and suddenly this dark cave is transformed into this bright, rather spectacular space. The light seems to bounce off the seabed and illuminate the whole cave. One swimmer on the last swim we did here summed it up perfectly. We arrived at the cave and she said “is this it!?”. Once she’d gone the whole way through her entire facial expression had changed and she said “…can we do it again!?”.

Before I’m inundated with exact location requests I’ll point out that to get to the cave you need the right conditions and tides. If you don’t do your research you could get in trouble. I won’t be handing out location info in a hurry.

Top 10 West Cornwall Swims

We’ve pretty much swum every inch of the west Cornwall coast. Here are our top 10 swims-ish. It’s really hard!

10. Prussia Cove - it’s not just the swimming but the whole experience. Beautiful, fairly quiet cove. Magical walk down. You can swim around to Keneggy or go west and back round to the start. Typically fairly clear water, always a bit chillier than other local areas though!

9. Swimming out through Porthleven Harbour (we definitely wouldn’t recommend this without an experienced guide!) and swimming SE along the beach. This is a hard one to beat in the right conditions. It’s difficult not to be impressed with some a stunning harbour.

8. Carbis Bay to Porthkidney and back. Crystal clear water and a white sand beach. Definitely worth doing at high tide.

7. Lamorna Cove. Can be a bit hit and miss. If storms and rough seas bring in seaweed it often gets stuck there for months. You get this beach right however, it’s like being in the tropics. Clear water, white sand, an abundance of fish…

6. Mousehole and St Clement’s Isle. Mousehole is one of my favourite places in the world. Stunning village and harbour. St Clement’s Isle offers a 1-1.5km swim (depending on how straight you swim!). Give the island a wide birth ensuring you don’t get too close to the seals.

Mousehole Harbour

5. Rinsey to Praa Sands and back. Loads of see on the way. A few caves and rock features to explore en route too. At the time of writing there isn’t much sand on Rinsey beach so might be difficult to get into the water.

4. Zennor. Again, this one is about the whole experience. Stunning village, followed by a stunning coastal walk. You have to scramble down the side of the valley to het to the beach…something that older, or less mobile readers may struggle with. For me though, it’s well worth the effort. Secluded bay, clear waters….don’t swim alone though and ensure someone knows where you are.

3. St Michael’s Mount. I think I’ve marked the Mount down, simply because I’ve taken so many groups around it. I don’t think I need to write much about the Mount.

2. Kynance Cove & swimming around Asparagus Island. Breath-taking swim. Incredible rock features, both on top and underneath the water. The walk down to the beach is worth a visit alone. Best swimming at low tide and get there early. It gets very busy in the summer months.

1. Porthcurno. World Class swimming here. Plan your swim for mid-low tide or on a small neap tide. It’s great at high tide but it just gets a bit deeper, a bit darker, the golden sands get lost a little under a high tide. You can swim over to Logan Rock or head west and take in the Minack Theatre.

Swimming at Kynance Cove

There’s no disputing that Kynance is a world class swimming location. The walk down to the beach alone is worth the visit! The only issue with Kynance Cove is the fact that it’s not a very well kept secret…and is usually quite busy. I’ve visited the beach before at 7am and there were a couple of kids on holiday body boarding! Get there early to ensure that you can park.

If you want a magical swim at Kynance Cove get there early. To be honest, once you start swimming you get away from the crowds anyway…but if you want a nice peaceful experience get there before the crowds. If you get there before the crowds be sensible! It is a remote beach, with very limited phone reception. So take precautions, take a friend, check the conditions….be SENSIBLE! At the time of writing lifeguards aren’t present at Kynance during any of the summer. Avoid obviously unfavourable conditions and big tide, particularly when the tide is going out.

Once at Kynance be careful getting down to the beach…it can be slippery and there is often loose gravel and stones under foot. There are 2 ways down, one an access road used for supplies (although the public can’t drive down it) and the second is the public footpath, at the back of the car park. This is steep in places and appropriate footwear is advisable.

Once on the beach there are lots of small stones and boulders to clamber over. I prefer swimming at Kynance at low tide, there’s more sand, better underwater views, easy access to the sandy beach side (far side of the beach) and more room in general.

Once in the water, there are a number of different swim routes. For the less adventurous swimmers I’d advise staying out the front, close to shore or popping through the gap at the far end of the beach (more picturesque on this side) and lots of rock features to swim around and explore. For the more adventurous you can swim around Asparagus Island. It’s around 2km in length. Be aware that you will be out of sight for some time on the swim. Stunning swim though and this swim should be on your bucket list!

If you are feeling adventurous and want to be safe get hold of a local guide.

For the first time we’ll be hosting a swim around the island (Asparagus Island) at Kynance Cove. This Bank Holiday Monday (31st Aug 2020). It’s a rare opportunity to get a guided tour around this stunning area.
