CV720 up Vall de Gallinera has lots corners to keep you busy. Through several small villages. From Planes there are two interesting detours:
a) North on CV711 with a drive over the dam of the lake, or
b) take the narrow road up to Gorg del Salt, park and take the short walk down to the river lake
Drive on to Vall de Ebo (may take a shortcut by CV712).
The most spectacular part of the tour is the finale; down to Pego from Vall de Ebo. Great road and views!
Suggestions for food and drink: villages in Vall de Gallinera (eg. Bar Placeta in Benissiva), Planes (Bar Lluis), Millena (Bar Millena)
Best to start from CV720 (hard to find junction midway between Castell de Castells and Benigembla). The first 200 meters have very rough surface, probably to discourage large campers from taking this route.
A good restaurant with great views on the top, about half way to Orba. The road down the mountain and Vall de Laguar goes through several villages and has some very nice views.
