We took the ferry over (5 minute ride for $7). We rented umbrellas for $25. We ate lunch on the beach. It was a great day. You can bring your own food/drink, but we ate at the restaurant. The water is calm and there are some small trails on the island. Definately worth a day trip. It can get expensive if you rent chairs, eat and drink also, it was well worth it to us!
