Oof – I post only to add our recent experience, as you plan on lots more cycling than us! We stayed at the southern tip in August, and it was great – just so refreshing to have lots of segregation (even if only a painted lane), loads and LOADS of people on bikes, and great bike-friendly weather.
We only jumped in the car once (ironically to go get bike stuff – tubes and rim tape), otherwise it was two weeks of going everywhere by bike. Easy to pop into town for supplies or to eat, lots of different beaches (water crystal-clear on the west coast but icy cold!), we never felt a need to leave the peninsula – looked like tarmac cycle paths all over the shop, but traffic in high season was so busy we gave it a swerve (looks like only one route on or off for cars, so big queues and prolly not much fun even to ride alongside in August).
Didn’t have a bad meal but La Mer A Boire was really nice, and we were big fans of grabbing a bottle of wine from Carrefour and sharing in the town square of an evening, there’s always stuff going on. Loved it – a type of holiday we’ve not been on for years, but can’t wait to do again. 🙂
