Oh you are near Sennen Cove, you must drive there the beach is amazing particularly if the sun is shining. We rent a cottage there most years, there is a pub there which does great food, fresh fish, salads etc great for low carbing, also there is a little cafe on the waterfront which does nice coffee. You can do some fabulous walks along the cliffs there and we have seen basking sharks and dolphins swim along the bay several times. You must walk along the cliffs to Gwenver beach, beautiful beach with enormous waves, fun to take a lunch and watch if you don't fancy a swim. Mousehole is worth a visit, absoutely stunning fishing village.
We have our own wetsuits and body boards and spend hours in the sea body boarding, great fun gives you an enormous buzz!
