The walk is right on the top of the ridge of hills along the coast. 650 metres down to sea level in 8km.
This was the best walk of the whole trip. Stunning views and so very quiet. Hardly anyone on the track which winds around the side of the hills and gives access to lots of little houses and vineyards along the way. Saw lots of little shrines along the way. Very magical experience.
Fantastic views but very pleased we did the downhill option as I would have died on the uphill option. Was supposed to take 4 and a half hours but took us 2 and a half even allowing for stops for photos and to enjoy the view (not rest stops, of course). Overtook a family with two five year olds which was the highlight of the trip and made me feel very fit.
The last section we descended 200 steps to find a sign that said: "1700 steps to Positano"
Took two days for my calf muscles to recover.
