Belle ile en mer hike Brittany
A fairly challenging hike in a stunning setting, but watch out for the relentless sun. Make sure to carry plenty of water, as there are no sources along the trail. Really glad we did it!

Belle ile en mer brittany gr340
A true joy to hike around the island before the tourists arrive, with a top-notch hotel to return to in the evening and dinners that were a real treat for the taste buds (you do need to like fish…). Simply excellent!
