Hi bounceagain, I have been lucky enough to go there twice(last time 2 years ago)and I must admit eventhough it's a small island the Piton mountains do take up quite alot of the island. We did hire a boat for the day and noticed that while there are alot of beaches, thy're not all connected so walking round would be difficult. The roads are 4x4 by neccessity as tarmac is only in areas around town. Hope you have a great time, snorkelling is a must!
