I took a bus from my hostel in Nice to this little town called Cap D'ail. Across from the bus station I saw a sign for what seemed like a trail. I crossed the road and down the stairs, through a tunnel and voila, discovered a path that hugs the Mediterranean coast all the way to Monaco!
While it was delightful to hop the French Riviera, via train, walking this stretch to Monaco resulted in delightful views of the coast, and breathtaking villas.
You won't see too many people on this trail and you will come across cute cafes where you can take a break before continuing on. It felt like I had made some secret discovery which added to my excitement even more, making it an unforgettable experience!
