So my trip originally was all about scuba diving, unfortunatly the more people you add to the trip, the more plans change; therefore we aren't getting to scuba dive nearly as much as we wanted to. We will have August 24-29th to do whatever scuba diving we want to do. We were thinking of day trips to Tobago Island, and Isla Grande, but i discovered Contadora Island. If I had to pick two which should I do? Which has the best scuba diving? I was thinking of maybe doing Isla Grande 24th-26th and then doing Contadora 26th-28th.. and i guess maybe for the day go to Tobago on the 29th for a few hours? Does this sound doable, and how much time do I really need at each place?
