Another excellent location is the northern bank near the Foz do Arelho beach and the sailing club. This section provides a different perspective of the lagoon where the salt water meets the fresh water. You will often see diving birds like cormorants searching for small fish in the deeper channels. The wide paths make it very easy to carry heavy camera gear or large binoculars comfortably.

The marshes of Covões provide a quieter alternative for those who want to avoid the main tourist crowds. These secluded paths wind through tall reeds and offer a very intimate experience with the local nature. You might spot rarer species here that prefer the dense cover of the thick lagoon vegetation. It is one of the most peaceful sections of the entire trail system for dedicated nature lovers.

• Arelho Observation Hides: Best for flamingos and herons.
• Foz do Arelho Banks: Great for spotting diving birds and gulls.
• Covões Marshland: Ideal for seeing small songbirds and shy waders.
• Mouth of the Lagoon: Perfect for watching coastal birds during high tide.

Rare Bird Species to Spot in 2026

In 2026, the lagoon continues to be a vital sanctuary for the iconic Greater Flamingo population. These pink birds are most common from autumn through the end of the winter season in Portugal. They gather in the center of the lagoon where the water is shallow and rich in nutrients. Seeing hundreds of flamingos take flight at once is a memory you will never forget.

The Grey Heron is a permanent resident that you can see standing perfectly still among the green reeds. Little Egrets are also very common and easy to spot thanks to their bright white feathers and dark legs. These elegant birds are masters of hunting and provide great entertainment for patient observers along the trails. You should also look for the Black-winged Stilt with its incredibly long and thin red legs.

If you are lucky, you might catch a glimpse of the colorful Common Kingfisher darting across the water. These small birds move with lightning speed and usually stay close to the quiet banks of the lagoon. Many migratory ducks and geese also visit the area during the colder months of the year. The diversity of species makes every walk a new and exciting adventure for bird watching enthusiasts.

Best Time for Birding on the Trails

Early morning is undoubtedly the best time to visit the lagoon for high-quality bird watching opportunities. Most birds are highly active just after sunrise as they begin their daily search for food and water. The soft morning light also provides the best conditions for taking professional photos of the local wildlife. You can find more details on the best time of year for Obidos lagoon walks online.

Tidal patterns play a massive role in where the birds will be located throughout the entire day. Low tide exposes large mudflats which are the primary feeding grounds for many different types of shorebirds. High tide pushes the birds closer to the vegetated banks where they can rest and stay safe. Always check a local tide chart before you set out on your birding journey for the best results.

Spring and autumn are the peak seasons for migration when many rare birds stop at the lagoon. During these months, you might see species that do not normally live in Portugal throughout the rest of the year. The weather is also very mild and pleasant for walking long distances along the scenic water's edge. Winter remains the best time specifically for seeing the large flocks of flamingos in the lagoon.

Planning Your Walking Route and Gear

Preparation is key to enjoying the best bird watching spots on Óbidos lagoon trails without any major issues. Wear comfortable hiking shoes as some sections of the trail can be quite muddy after a heavy rain. Bring a pair of high-quality binoculars to see the birds clearly from the designated observation points. The easy walking paths around the Lagoa de Óbidos are suitable for walkers of all levels.

Always stay on the marked paths to avoid disturbing the sensitive nesting areas of the local bird populations. Keeping noise to a minimum will significantly increase your chances of seeing the more shy and rare species. It is also helpful to wear neutral colors like green or brown to blend into the natural environment. Respecting the local ecosystem ensures that these beautiful birds will continue to return to the lagoon every year.

Finding a place to leave your vehicle is simple if you know where the main trailheads are located. You can learn how to get to Lagoa de Óbidos trails by following the signs for Arelho. There are several free parking areas near the most popular birding spots on the southern shore. Remember to bring plenty of water and sun protection as there is very little shade on the trails.
