If you make it to the top you will be rewarded by a 360 degree view of the surrounding area. You can easily see the mainland, Glyfada beach on the distance, Ermones beach on the opposite direction, golf courses, Ropas valley, Pelekas, Corfu town, Vidos island, Mathraki island on the distance and many other landmarks.
You will need hiking shoes, some water. The path is shaded by folliage on the last 2 / 3 of the distance.
The cache is a small plastic container containing logbook, pencil, small greek booklet some shells from the beaches we visited.
