Epphaven Cove is a small cove that is adjacent Lundy Beach and Lundy Hole and usually linked at low tide and is often mistakenly referred to as part of Lundy Bay.

The upper part of the beach is rocky and most of it gets covered at high water. However, as the tide retreats areas of fine flat yellow sand are exposed, and numerous rock pools, but there is little or no beach at high water and access from the path becomes very hard.

Swimming is not safe at low water but when conditions are favourable swimming can be undertaken on a rising tide in the upper part of the Cove providing it is done with care. Surfing an hour or so either side of low water is possible but within the Cove is not recommended at all.
