Very quaint town for a 1 day visit only. Hilly and pitureresque. Place for a romantic evening meal with your loved one. Nothing to do except walk around the little lanes, tourist tat shops and look at the views.
Le Lavandou is a tired old seaside town. Very run down with cheap looking shops (not many). There is 1 stretch of about 10 restaurants but none are special.
Beach is not nice. Drive 15 minutes along the coast to the natural beaches of L'Estagnol. Parking at all natural beachs is 8 Euros for the day because they are on private land. Good thing, these beach are only really visited by French tourists and a few English and German.
