Walking west from the ferry dock, up the hill and towards the barge wharf: St. John Boutique Hotel, Grande Bay, Lavender Hill, Gallows Point, Star Villas, Coconut Coast, Palm Terrace, Battery Hill, Hillcrest, Tamarind Court, St. John Inn. Samuel Cottage are a short walk up Centerline Road. Cruz Views is further along up Pocket Money Hill. Most of these are on TomB's link.
Walkable depends on the walker. I can walk Cruz Views and Hillcrest, my lady is not so inclined. It's a $5 cab ride at the end of the night.
