The Smugglers at Osmington Mills, White Nothe - if you read Moonfleet years ago that is were the zig-zag path comes up where they escaped from the excise men, The Pelican of London (tall ship) if she's moored in the harbour (Weymouth is her home port), Durdle door, fossile 'forest' at Lulworth.
Only 11 miles but some could steep bits. Have fun
Did you go round Portland?
