If you love wild swimming, secret coastal adventures, and stunning scenery, then this hidden natural swimming pool of the Trescore Islands is a must-visit. Tucked away between Porthcothan and Mawgan Porth, this magical tidal pool is revealed only at a very low tide, making it one of Cornwall’s most enchanting coastal gems- and one for only the brave! Here’s everything you need to know about finding it, where to park, and how to stay safe on your adventure.
The best way to reach the secret swimming pool is by following the South West Coast Path from either Porthcothan Bay or Mawgan Porth.
There are two routes to walk to find the islands, both following the South West Coast Path.
Option 1: Start from Porthcothan Bay Parking: Use Porthcothan Beach Car Park (PL28 8LR), a short walk from the beach.
Route: Follow the South West Coast Path north for about 2 miles towards Trescore Islands.
Expect breathtaking clifftop views, rugged coastal beauty, and plenty of hidden coves along the way.
Option 2: Start from Mawgan Porth Parking: Use Mawgan Porth Beach Car Park (TR8 4BA) near the beach.
Route: Follow the South West Coast Path south for around 3 miles, passing scenic cliffs and dramatic rock formations before reaching the pool.
Both routes offer stunning coastal scenery, making the walk or hike as enjoyable as the destination.
Warning: you are doing this walk at your own risk. Do not attempt this trip alone, the area is quiet, even during summer, and there are no lifeguards around. There is a ramble down some rocks to get to the base to swim off from.
This hidden tidal pool is located just beyond Trescore Islands, naturally carved into the rocks. It only reveals itself at low tide, so be sure to check tide times before setting off. The best way to find it is by keeping an eye out for a rocky outcrop with a deep, crystal-clear pool nestled within.
Best Time to Visit: Low tide on a calm day ensures safe access and the most stunning swimming experience. It’s also a fantastic and safe, sheltered bay to stand up paddle board.
What to Expect: A natural seawater pool with sheltered, calm waters, perfect for wild swimming. On sunny days, the water shimmers in beautiful shades of blue and green.
While this hidden gem is an incredible spot for a swim, safety is key when exploring tidal pools:
Check Tide Times: The pool is only accessible at low tide and can become dangerous as the tide comes in.
Be Cautious of Slippery Rocks: Wear sturdy shoes for the coastal walk and when climbing down to the pool, as you will have to clamber down over rocks- there is no path down to the bay.
Swim with a Buddy: Always let someone know where you are going and avoid swimming alone.
Watch for Strong Currents: The pool is sheltered, but surrounding waters may have strong tides, so stay within the natural rock formations.
Respect the Environment: Keep this secret spot pristine by leaving no trace and respecting local wildlife.
For those looking for hidden, and more tranquil 'off the beaten path' things to do along the Cornish coast, this secret tidal pool is an unforgettable experience and is still very unheard of. Whether you’re a wild swimming enthusiast, a coastal explorer, or simply searching for a magical secluded spot, this natural wonder is a must-visit.
If you’re ready to discover this hidden swimming spot, lace up your walking boots, pack your swimsuit (or even a wetsuit!) and set off on one of Cornwall’s most breathtaking coastal adventures. Have you found any other secret spots along the South West Coast Path?
