We've stayed at Trewethett Farm site several times over the years and cannot fault it. Well maintained site, good facilities, large pitches, friendly and helpful wardens, great location with most pitches overlooking the sea so can be windy at times, cliff walks into Tintagel and Boscastle. Nearby Padstow is certainly worth visiting but very busy throughout the season. Nice walk down to the cafe in the bay overlooking the castle and for the less energetic, a useful Landrover ride back up to the town. Highly recommend this site but book early as it is very popular.
