We went on the Lamani trip with Seaduced. The tour guides were very knowledgeable and friendly. It does make for a very long day. You are in a boat or van for about 4 hours getting there and 4 hours back. The van ride was very bumpy over gravel roads. The ruins were great and interesting. On the way we saw a manatee, croc, birds, and howler monkeys greated us with their howls at the dock in Lamani. The trip back on the boat was very rough due to large waves that came in during the afternoon. The tour guide said that was very unusual. Be sure to sit at the back of the boat for a smoother ride!
