Although the rooms are typically English B and B (i.e. few and small) in this little B and B, the location and the friendly hosts make this well worth a stop on the way to Tintagel or elsewhere in Cornwall.
The drive down the hill into Boscastle requires good breaks while the view is fantastic. The owner of the B and B is part of the light house organization and can tell you a lot about the area. The owners will also point you to a very cool nearby pub for dinner or a pint. The B and B also offers a very full English breakfast, but you have to get up early for it.
The highlight of this B and B is its location on the harbor. Don't picture big docks or boats, instead think of a gorge in the mountains where hearty fishermen a high tide could enter the mouth of the mighty Atlantic. It's about a five minute hike up a marked path along the harbor edge to a perch on the cliffs that you can sit and watch the waves crash in below you. We climbed out there at night (suggest choosing moonlit night and caution here) and just sat in silence while we watched the waves crash about 100 feet below us. We also went back up in the morning after breakfast where we discovered that the cliff top is covered with lichen and little flowers. There's also an impressive view of the coast. Also in daylight you realize there are a couple of shops where you can buy local crafts and candy.
