Bermuda is stunning. We had exceptional weather. We purchased the 3-day the bus/ferry pass for $35. The island is easy to navigate, so we toured the island on our own and had a blast.
First day, we jumped on a bus and went to Gibb's Lighthouse. Incredible view of the island. We then hopped on another bus and went to Warwick Beach. Much less crowded than Horseshoe and I think even more beautiful. It is one stop past Horseshoe.
We visited St. George and did a $5 walking tour from the Town Hall. We then hired a taxi for about $25 to take us to a Glass Beach and for a couple of quick stops on the outer areas of St. George.
On the bus ride back, we hopped off and did the caves. A bit pricey, but interesting.
On our last day, we went Hamilton in the morning. Unless you are a shopper of high end goods, I wouldn't waste your time in Hamilton, except for bus and ferry transfers. After a very quick visit, we took the ferry back to King's Wharf hopped a bus and went to Black Bay (a few minute bus ride) for a quick swim. It appeared to be mostly locals at the beach. After our swim we went to the National Museum in King's Wharf. I wish we had more time there. It was interesting and offered a unique view of the ship.
If you've never been to Bermuda...do it!!! We'll be back.
