Rather easy hike, with beautiful views on the gorges of the Guiers river and the countryside. On the plateau of La Ravoire, many different species of birds live together in the splendid forest. Enjoy the song of the numerous wren and winter wren.

(1) From Pont Saint-Martin, take the Échaillon trail, which winds its way up to the Ravoire plateau. Follow the GR9 markings eastwards and take the trail overlooking the Échaillon gorges, where the Guiers Vif river flows.
(2) The trail passes close to a viewpoint, where caution is advised (no barrier). Return to the GR9, then leave it about 500 m further on to turn north (yellow markings).
(3) Cross the prehistoric site of La Fru to reach the Charmilles car park. Follow the GR9 for about 200 m before joining a yellow-marked path on the right. Cross the Ravoire plateau to the crossroads marked with a signpost.
(4) From here, you can make a round trip to a superb viewpoint overlooking the hamlet of La Grotte. Return to the crossroads and take the yellow-marked path southwards. After walking along the escarpments overlooking the valley, join the GR9 to return to the starting point.
You can admire the gorge by crossing the Roman Bridge, but caution is advised with children.
