Arenal Observatory Lodge & Spa 3-day Itinerary.
Planning how to best spend a two-night, three-day stay at the Arenal Observatory Lodge & Spa in La Fortuna, Costa Rica is no easy task. With a complimentary morning walk, two observation towers, a pool and jacuzzi, a variety of spa treatments, a historical museum, horseback riding tours, some of the best birding in the country, 7 miles (11 kilometers) of trails to explore across 870 acres (352 hectares) of property, and much more to offer, finding time for it all can seem an impossible task.
