The easiest place to park is the car park at the Convent of Saint Dominic in Corbara; you can reach it from the D151 via a small road on the left as you approach from Corbara.
(S/E) At the end of the car park, turn right onto a dirt track that slopes down slightly, then take a path on the left (with steps) marked in yellow (San Antonino).
(1) After about fifty metres, carry on straight ahead. The path becomes quite easy to walk on and the view is very interesting.
(2) The path first follows the contour line, then climbs steadily until it passes just above a water collection point (a slight descent, then the climb resumes). The view over the Balagne is truly extraordinary. In the foreground, below, lies the village of Pigna.
(3) After joining a dirt track and a slight false flat, you’ll reach the lower part of the village of Sant’Antonino. Take the opportunity to explore the village (which is quite touristy) and, if you like, climb to the top for a 360° view. Retrace your steps along this route to return, heading down towards the Convent of Saint Dominic (S/E).
