Glen Beach is south of the harbour at Saundersfoot. Access from Saundersfoot harbour down an easy ramp. Alternatively at the bottom of The Glen (the first turning on the left after St Brides Hill out of Saundersfoot), a small parking area and some roadside parking is available, and beach access from here is a tarmac path with some steps. Alternative parking is at Saundersfoot.
The shore consists of sand, rocks, small streams and rock-pools, backed by cliffs of mudstone and sandstone. Opposite the harbour is a classic example of an anticline known as Ladies Cave, beyond which are three small sandy coves backed by shingle and wooded cliffs. The first of these is St Bride's Bay (not to be confused with the larger bay of the same name on Pembrokeshire's west coast). The next along is backed by shingle and high wooded cliffs, with an old mine adit towards the back corner. The third is Swallowtree cove, which provides access to the coast path and is popular for high-tide swimming and fishing. As these beaches face east, the upper shore becomes shaded towards late afternoon. Around low tide it's possible to walk to Monkstone Point (in the distance above) and Monkstone beach.
Dogs are allowed at all times and toilets ♿ are available at Saundersfoot harbour.
