Just came back from a glorious few days last week at Bolberry House Farm. Left the car on site and walked to three different beaches!!
(To be fair the nearest beach is a good half hour walk - but just a five minute drive). On two evenings I stayed on the nearest beach till gone 6pm eating fish and chips from the local cafe that did takeaway - so didn't even need to cook after the walk back up to the campsite.
Best walk was from the site cross-country through wheat fields, country lanes and woodland and ending up an hour and a half later at the 'Winking Prawn' beach cafe at Salcombe North Sands for a buffet breakfast overlooking the Salcombe Estuary. Spent the day on the beach and then caught the bus back to the campsite.
