There are so many fun things to do in Costa Rica! You can book an excursion through the hotel or we also recommend booking through North Pacific Adventures. They offer activities such as: hot springs and waterfall hikes, volcano tours, zip-lining through the jungle, ATV rentals, whitewater rafting, wildlife tours, horseback riding on the beach, and fishing trips where you can bring your catch back to the resort to get prepared and cooked for you!
Download this app and input the hotel name to get all the info you need during your stay! The app has: the resort map, a list of all the restaurants and bars, daily free activities, nighty show information, housekeeping requests, spa menu, shuttle transfers, and room service ordering! We used this app throughout our entire trip last year and we found it immensely helpful to get the most out of our stay.
