You are unlikely to notice any snakes unless they are pointed out to you by a naturalist guide.
Yes, we have snakes, lots of them, and some that are extraordinarily beautiful. The most dangerous is the bushmaster, which is very common in sugar cane fields. Fatalities from a snake bite for anyone in Costa Rica are extremely uncommon. Locals and tourists killed in car accidents are a lot more common! The most dangerous activity undertaken by most adventure companies in Costa Rica is to drive on public roads, especially at night, in the fog, with no yellow lines or white lines, no place to pull off, with nothing to mark huge potholes that might have formed the last time it rained. Snakes hardly rank in comparison.
While hiking, the opportunity to meet multi-legged or legless creatures is increased. We want you to know what to do when you encounter snakes, etc., before we start off into the forest. Serendipity does NOT carry snake antivenin (antivenin can kill as fast as the snake) but our staff are trained on how to handle snake bites. To date, we have not needed to use our snake bite treatment training, so please don’t break our record. Listen carefully to your guide on how to introduce yourself to a snake, and how to know which snake is which.
