I would bring some good sturdy hiking boots in addition to my wading boots. Wear the hiking boots to walk wherever it is you are going.

Unless you get an early seat on the ferry you'll be standing, and if youre not comfortable then(comfortable boots). By the time you make it off the ferry and start walking you'll be miserable. A comfortable backpack, and proper plug selection so you're not hauling everything under the sun around the island. It aint easy by any means but if sure is freakin fun!!!
