The kitesurfing school is beautifully located, but I don't know if you're even allowed to surf in that area of the city beach.

In this area, the sea is very close to the row of parks behind it and kitesurfing is permitted.

A Touch of Fantasy Malo-les-Bains is a lively seaside resort where Belle Époque villas exude a touch of fantasy. Book a small hotel just steps from the beach, lay your towel on the golden sand, and enjoy the lively atmosphere.
