Even though we are staying on the beach, I'd like to do some wandering up in the cliffs area. I've read everything from 'be careful' to 'don't go anywhere on foot'. Is there any particular area that is recommended for strolling and exploring? We'll only be there a week so might only get to spend one or two days in the cliffs. Was thinking about Xtabi, would that be a good starting point? Any tips/must-sees for strolling the cliffs?
