My husband and I plus 2 friends are thinking about scuba diving in Costa rica on out trip there in Mid November. I have dove in many tropical places including Hawaii and Cozumel and great lakes ship wreck diving, while the other 3 have never dove before. My question is, is it worth it to learn to dive so that they can dive there? Is there a lot to see? Is the water warm? We will be staying in Nosara so the trip would be taking off from San Juanillo. Thanks for your help!
