A very beautiful place, even without seals.

The scenery is very beautiful, with lots of birds, cows, horses, and sheep. The road is made of pebbles and quite strenuous to ride.

Unfortunately, it's not that easy to see the seals, which is a shame.

A gravel path. A bit monotonous and technically challenging to ride on a bike. Wide tires are essential, and suspension is helpful. The view is fantastic. The cliffs of Ault are in front of you, the sea is to your right, and the nature reserve (salt marshes) is to your left, with many seabirds, horses, and other wildlife.
