Glen Beach is south of the harbour at Saundersfoot. Access is from the harbour down an easy ramp, or alternatively from the bottom of The Glen (the first turning on the left after St Brides hill out of Saundersfoot). Roadside parking for about 10 cars is possible here. 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. An old mine adit is at the back corner of the next cove along, and access to the coastal path is possible at the third (Swallow Tree). 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. These beaches are good and generally safe for swimming at high tide.
Dogs are allowed at all times and toilets are available at Saundersfoot harbour.
