The lagoon becomes narrower toward the North. Still some sandy beach coves right along the Eurovelo1 bike route offer safe and warmer water to swim than across the peninsula on the ocean side, particularly useful early in the season.

The entire narrow peninsula separating the lagoon from the ocean is formed by a sand bank deposited off the prehistoric coastline that eventually closed in and filled with water. It is hugged by a wide road with a good shoulder for biking, all the way from the Sao Jacinto ferryboat dock at the southern tip, to Ovar in the north, with two small beach towns in between, worth a detour. To keep it straight, this section highlights the longest part, from the southern tip to Torreira. The middle section goes from Torreira to the bridge that crosses the lagoon to th east, and the norther section goes from the bridge to Ovar, where the peninsula ends. The Ria (lagoon) continues as a natural canal parallel to the coast for another 50 kilometer or so to the north.

Right across from the entrance to the Sao Jacinto campground are several docks for the small, colorfully painted traditional lagoon fishing boats still used by local fishermen.

On the lagoon side of the road the local fishermen continue to attach their traditional small shallow boats and also fish with rods from the wooden piers. On the other side a trailhead with picnic tables and restroom is a good rest area with a quick trail to a marshy pond in the nature reserve promising great birding opportunities.

The coastal Eurovelo 1 bike trail runs along the large protected estuary. Partially on dedicated trail separated from vehicle traffic, partially sharing the shoulder of the road. It's nicest going south to north to always be closest to the water.
