Yes, bringing a picnic is a great idea. There are many scenic spots along the trail where you can stop and enjoy a sandwich while taking in the stunning views. Or, if you end the hike at Plage de la Garoupe, there are a few nice restaurants to choose from, including Le Rocher and Le César. Or, if you fancy ditching the picnic and pushing the boat out, Eden-Roc Restaurant serves upscale lunchtime seafood with a stunning sea view.
