Does anyone know anything of interest in walking distance from the port? I know of the stores immediately off the boat but didn't know if there was anything else to safely explore (1 mile radius)

Thanks!

No, nothing close by. If you like snorkeling, I highly recommend going to Champagne Reef. I prefer going by boat, but they have built a cat walk so it's easier to get into the water. It's a fantastic snorkel. It's about a 10-15 minute cab ride.
