Section 1 of the Cornwall 100 mile challenge runs 14 miles from Boscastle to Port Isaac and is graded 5 miles moderate and 9 miles severe. A tough first days walk along the best section of the north east Cornwall coastline. Steep climbs and descents take you down to hidden coves, along twisted towering cliffs, past bronze age cliff carvings, King Arthur’s Castle and Merlin’s Cave at Tintagel. Rest up with a pub lunch overlooking one of Cornwall’s classic rocky cove beaches at Trebarwith Strand, before an exhilarating afternoon climbing and crossing 7 valleys, through cliff top mining remains on route to Port Isaac.
