A Day to Observe, Discover, and Connect with Nature
Every year, thousands of people around the world come together to take part in one of the most important citizen science events supporting biodiversity conservation: Global Big Day.
On October 10, 2026, Arenal Observatory Lodge & Trails will join this international celebration, welcoming birdwatchers, nature enthusiasts, photographers, and travelers who want to discover the extraordinary biodiversity found within our forests.

What Is Global Big Day?
Global Big Day is a worldwide day of birdwatching and bird recording organized through eBird, a global platform developed by the Cornell Lab of Ornithology. On this day, people across the world head outdoors to observe birds and record the species they encounter, contributing valuable information to the study and conservation of biodiversity.
Every sighting counts. Every observation adds to our knowledge. And everyone can be part of this global citizen science effort.

A Remarkable Setting for Birdwatching
Located at the foot of Arenal Volcano and surrounded by more than 350 hectares of protected natural habitat, Arenal Observatory Lodge & Trails is a remarkable destination for birdwatching in Costa Rica.
More than 500 bird species have been recorded on our property, including hummingbirds, toucans, tanagers, motmots, hawks, and many other species that find food, shelter, and habitat within our diverse ecosystems.
Our network of trails, gardens, observation towers, and forested areas offers countless opportunities to discover wildlife while enjoying the peace and beauty of the surrounding landscape.

More Than Birdwatching: An Experience of Connection and Conservation
Global Big Day is not only for experienced birdwatchers. It is an opportunity to slow down, listen to the forest, observe more closely, and appreciate the extraordinary biodiversity around us.
Every bird we encounter is a reminder of the importance of protecting the ecosystems that sustain them—and of recognizing nature as our greatest treasure.
