I booked a half-day snorkeling trip for my family group of five adults with North Pacific tours before our first trip to Costa Rica. I picked North Pacific because the email communication with Lisa was prompt and professional. Some in my group were a little nervous before the trip as we had booked this sight-unseen but we were all immediately put at ease when the very experienced, friendly, and fun Mauricio and Captain Dan pulled up at the beach in front of our resort. They took us to a couple of secluded snorkeling locations and really tailored the day to our interests and abilities. We particularly enjoyed Mauricio snorkeling along with us and giving my nephew and I tips on free-diving. We just had a wonderful morning. I only regret that we were not able to also squeeze in an additional fishing trip with North Pacific. I highly recommend these guys.
