Cat Clark: There are many beautiful swimming spots along the East Lyn - but Long Pool is a family favourite of ours. Either use it to cool off after walking upstream along the footpath, or, if you intend to head downstream to the Watersmeet tea rooms afterwards, as an excuse for a big slice of National Trust cake!
It's fairly deep, and as the name suggests, long - with a beautiful waterfall at one end. You'll see it signed from the path. From the sign, carry on down the hill, cross the footbridge and walk back upstream.
There's a few low ledges you can safely (look before you leap!) jump in from. If you're not feeling up to that challenge, a more leisurely slither from the rocks that edge the pool is also possible :)
All in all - a beautiful spot for a dip. Dense woodland means it feels very secluded considering it's not far from the footpath.
Shockingly cold water! The East Lyn can also flow very fast at times, as it channels a huge amount of water off Exmoor. Also lots of overhanging trees, so check for submerged branches etc (although I've never had a problem with these.)
