Glenthorne Beach straddles the Somerset / Devon border, and is a beach of rocks and pebbles. There is a small waterfall here, a few small caves an old lime kiln and the ruins of a boathouse behind the beach. North-facing and backed by high cliffs, it doesn't get much sun.
The nearest (free) car park is at County Gate on the A39, which has toilets ♿ and a bus stop. The car park has extensive views across Exmoor to the south and the Bristol Channel to the north, and is perched high above the scenic valley of the east Lyn river.
There are two possible routes to the beach, beginning either just west of the car park or just to the east. Both are well signposted as they descend the 1060 feet through the wooded cliffs to sea level. Rhododendrons grow wild alongside the paths; as these are regarded as an invasive weed in woodland, no-one is likely to object to a few being removed for the garden. Other paths lead off in most directions from the car park which is a good base for an afternoon's walking. Westwards from Glenthorne, the rocky shore becomes more difficult to walk over, and there is no further access to the shore until Lynmouth.
