Hi there, I am coming to Costa Rica for the first time at the end of July and am very excited about the possibility of being in Nosara during an arribada. I realize there's no guarantee, but will keep my fingers crossed! I am also interested, if it's safe, to go swimming in the ocean with turtles. There is a tour company that offers a boat trip to swim with turtles, but I do not want to do this activity if it puts the turtles in any jeopardy whatsoever. I am a bit concerned about how a boat with a propeller is able to safely navigate around turtles and make sure that they will not be injured by the propeller. I notice that only one tour company offers this activity so it does make me wonder if it is safe and ethical to do this. If it is, then why wouldn't all the tour companies do this? Would greatly appreciate any input on this, as the last thing I would want to do as a tourist is risk harm to any wildlife that I am hoping to encounter while in Costa Rica. If this is an acceptable activity, can anyone recommend a responsible tour company to book with? Thank-you!
