Are there water taxi's that go to Hopkins from San Pedro? Is it feasible to go to Hopkins for a day trip or is it better planned out for a longer time?

To far for a day trip... having said that for sure someone will tell me about how it was done, but No routine or organised tours , because of the distance. Better to spend a couple of nights in a hotel down there.

Thanks Elbert! We'll be in SP in 21 days! I really want to go to the Mango Festival but we have people coming to San Pedro that we have to meet on the 4th soooooo...I guess no mangos for me this year!
