We just in Guanacaste last Feb/March. Found the diving to be very good. Differant from most Caribbean diving. No coral to speak of. mainly rock bottom. it reminded me a lot of diving in the northern portion of the Sea of Cortez around Guaymas/San Carlos area. The weather was perfect. Visiblity was in the 75 foot range. Huge schools of fish. lots of gray tip and bulls. I really enjoyed some of the shallower divers. several sea horses, clown shrimp were very cool. Also a hyperactive cushion urchin that had flourecent blue dots all over them. I actually have a DVD I burned of the dive. I take HD Video of most of my trips. If youd like I can send a copy. One of our dives we went on a search for a whaleshark spotted by another boat, but no joy. Next week we are trying Belze.
