Highly recommend Roldan to guide you anywhere anytime during your stay in Huatulco! We went snorkeling and kayaking and never have I had such a comprehensive, fun and dynamic tour. I saw a total of eight sea turtles, hand fed little fish, went cave diving and explored the reef all with Roldan guiding me, filming me and adding informative tid bits about the local flora and fauna. Super affordable for the quality and content of the tour, seriously the best tour guide Huatulco has to offer.
