Birdwatching
Birdwatchers can enjoy four observatories located across the three lagoons, each offering prime views of different species:- Main Lagoon: With diverse terrains, depths, and a variety of vegetation, this is the best location to observe the highest diversity of waterfowl gathered together.
- Shallow Lagoon: The perfect place for watching waders in action, as they dominate this area.
- Large Lagoon: In this lagoon, it’s common to spot large groups of ducks.
Nature Photography
Nature photographers will find EVOA to be a paradise designed specifically to capture images of waterfowl in unique conditions. We offer three photo hides specially built to enhance image quality:

- East-Facing Hides: Two hides are positioned to the east, overlooking the Shallow and Large Lagoons. These are ideal for photographing in the early hours of the morning, taking advantage of the soft morning light. The proximity to the water allows for bird-level shots when the birds are resting, creating engaging and dramatic perspectives.
- West-Facing Hide: A third hide is located to the west, offering excellent conditions for photography in the late afternoon, with proximity to the water and unique angles during the golden hour.
Photography Tip: Combine the soft light of the morning or evening with high tide timing. Since the lagoons at EVOA are tidal refuges, many birds seek shelter here during high tide, providing incredible photography opportunities, especially when paired with the best lighting conditions.
For more serious photographers, we offer an extended experience, with access to the hides before dawn and until dusk, maximizing your chances of photographing during the best light. Click here to know how to become a member.
Additionally, you can reserve an exclusive photo hide at the Shallow Lagoon (5€/hour) for an uninterrupted experience.
For more inspiration and to exchange experiences, we invite you to join the EVOA Photography Facebook group, where you can view photos taken by other photographers over the years and share your own images.
