From downtown Antibes, take bus 10. After 10-15 minutes get off at the stop F. Léger in Biot. Don’t forget to say Merci, Au Revoir to the driver as you leave the bus (the locals all do). Then walk for about 3 minutes and you will find a lovely little museum, in a park, with works by Fernand Léger, including mosaics and stained-glass windows. If you plan on having lunch there, make sure you go to the little outdoor bar early as they may run out of sandwiches!
Then go back to the bus stop to take the bus all the way up to the village itself and find for instance this door that just sits high up on a wall and take a stroll before getting on the number 10 bus towards the coast again. And may I remind you to say Merci, Au revoir to the driver when you get off.
