This street is majestic. I walked both sides in the street's entirety--from Castle Hill down to…read moreParc Phoenix (on the Mediterranean side) and from Parc Phoenix back to Castle Hill (on the hotel/casino/city side). In truth, both are worth exploring, but it can be a bit much (about 4 miles each way). If you aren't up for that, I recommend staying seaside, but make sure to cross and check out Hotel Negresco and Villa Masséna Musée on the city side.
I got an early start (I was out there around 07h30 on a Saturday, and it was great. The sunrise was beautiful through the clouds, and the seaside breeze was the perfect accoutrement to mid-seventies weather. For anyone going to Nice, taking a stroll down the Promenade is an absolute must. At the very least, I would walk from Castle Hill down past the beaches (closer to 2 miles instead of 4). Such a great experience!
Enthusiastically,
