The iron bridge at the end of the walk, Ponte de Belver, was designed by engineers associated with the Gustave Eiffel school of construction.
The Tagus River in this region acts as a natural border, separating the municipality of Gavião from the historical region of Belver.
The boardwalk serves as a vital component in preserving the riverbank's erosion-prone sandy soils.
Belver Castle, visible from the entire boardwalk, was donated to the Order of the Hospital in 1194 to guard the river entrance.
Passadiço de Alamal is a 1.5-kilometer wooden boardwalk winding along the south bank of the Tagus River in Gavião, Portugal. It connects the Praia Fluvial do Alamal to the historic Belver Bridge. The route offers continuous views of the river and the medieval Belver Castle situated on the opposite hillside. The path is built primarily of wood and metal, featuring sections that run directly over the water. It provides an accessible way to traverse the riparian zone without damaging the local ecosystem. The trail ends near the base of the Iron Belver Bridge, an industrial-era construction dating back to the early 20th century. Visitors can observe local riverside flora and fauna along the transition between the riverbank and the adjacent woodland. The boardwalk is relatively flat, making it suitable for casual walkers.
