This is absolutely one of the best properties I’ve stayed near La Fortuna. From the time I arrived, front desk was helpful and informative. My room was not ready yet, but I occupied myself with a brief visit to their museum, sat/stood on the viewing deck observing birds feed on fruit, coatimundi roaming the garden, and listening to Yellow Throated Toucans chattering in the forest. View of Arenal Lake was wonderful! I stayed only 1 night, and wished I had stayed longer. I will plan on a longer stay in the near future. To truly enjoy Arenal Observatory Lodge and Trails, recommended stay is 2 or 3 nights to get the most of everything this property offers. I enjoyed my morning bird watching tour. My guide, Raul, and I found 43 species of birds in two hours. I walked a couple of trails alone after that. The wildlife is spectacular here as well as fantastic views of Arenal Volcano! My room was very comfortable and quiet, located across from the restaurant. Breakfast was very good with several selections to choose from. I did wait more than 30 minutes to be served my breakfast. Apparently, I was forgotten as I sat there observing other guests who arrived after me being served in a timely manner. That was the only flaw in service. Otherwise, everything else was satisfactory!
