Costa Rica has some venomous snakes; hence you should not go through high grass without proper wear (boots and long pants). Always watch out what you touch or where you step. Snakes will bite you when they feel threaten, so you want to avoid seeming a threat to them. Keep the doors of the house closed at night or when you are away. If you do see a snake, do not attempt to catch or kill it. Call the caretaker (Gumercindo). He will take care of the problem. If you get bitten, let someone drive you immediately to the Cortez Hospital, 35 minutes south of Uvita.
I first came to Costa Rica in 1998. I fell in love with the country right away for so many reasons. I have been coming, living and unfortunately never staying off and on since.
