I am staying in Hyannis from July 3-6 and taking the Hy Line Ferry out to Martha's Vineyard on Friday, July 5. The ferry terminal is in Oak Bluffs. Having never been to Martha's Vineyard, I am looking for the best beach to visit for the day. We plan on taking a taxi from the ferry terminal to the beach and I am trying to decide which beach to visit. Heard nice things about Moshup Beach in Aquinnah, but it's a haul from Oak Bluffs and I am told there's a 10 minute walk to the beach. Am I wasting my time or is there a better beach closer to Oak Bluffs? For instance, Joseph Sylvia State Beach? Katama Beach south of Edgartown? Any suggestions are welcome!
