A footbridge leads over the stream that flows into it. However, the stream is under water when the tide is about 4 metres high. This should be taken into account when planning a hike.

Kernic Bay, located in the ornithological reserve which runs to the Goulven strike to the west, constitutes an exceptional place for observing wildlife. Throughout the year, birds number in the thousands. Don’t forget your binoculars!

Over more than six kilometers, the Kerrema dunes constitute an exceptional space where dune flora exults. Dunes play a primary natural role: they protect land from sand blown by winds. Be vigilant and stay on marked trails.

Built from robust granite, it stands out against the horizon, its silhouette in constant dialogue with the endless sea. As a sign of faith and devotion, it is surrounded by an impressive cross and an artistic Calvary, whose attention to detail tells stories from times long past. A stone path, a staircase of irregular steps carved directly into the rock, leads up to the chapel. It's as if the stones reveal a piece of their history with every step. Once at the top, a panorama unfolds that takes your breath away: the wild beauty of the Pagan Land and the endless sea that stretches to the horizon. Not far from the chapel, a peculiar stone gatehouse testifies to the vigilance of bygone times. Here, at this natural observation post, Coast Guard customs officers monitored every corner of the coast, always ready to respond to possible approaches. This gatehouse, accessible via another staircase carved directly into the rock, is a silent witness to stories of courage and determination. The current chapel of Pol, lovingly restored and rebuilt in 1870, stands on the site where there was once an asylum of St. Pol Aurélien, the first bishop of Léon.
