Just got back from a trip to Japan and we did a day trip seeing some of Kamakura and nearby Enoshima. It was breathtaking and one of the highlights of our trip but be forewarned, there are A LOT of steps. You basically go up and over the island on your way to the caves and the tidal pools/rocky shore. The fun part is, this isn't a loop. You just have to do it all over again in reverse.
Totally worth it IMO it's just about a 200 ft of stairs that you have you do twice. If you have mobility issues, there is no option past a certain point.
