I have to disagree with the other reviewer of St David's. I made the time to visit the area, and took a hike round Great Head and Little Head Parks on one visit and took to the beaches on another. The nature trail was beautiful, as I say away from a lot of tourists that flock to St George. There wasn't much to look at the forts, but the views along the trail are magnificent. The number 6 bus will drop you right at the entrance to the parks and it's easy to find the trail.
Clearwater beach is a tourist attraction but a bit less accessible than many of the others in Bermuda, but is a long stretch of perfect sand, around the corner are smaller bays like Turtle Bay. I've only visited outside of the summer season, and have a bit of a hike from the bus route to the beach but well worth the effort.
