In reply to Ed Bright:
Both have loads of climbing on offer. Probably more newly developed crags around Gandia as well as old favourites. If staying in/near Gandia there’s also easier access to Montesa, Bellis, Aventador, Tallat Roig, Alzira to name a few. Not sure what it’s like for eating out, but whenever I’ve been into the town it seems pretty busy so no doubt there’ll be a good choice of restaurants.
obvs lots of rock around Sella too and some really nice newer developed areas. Not sure what the access track is like after the recent storms (the rain has washed away some tarmac roads and Sella only has a rough track)!
Not much choice of eateries in the village, but Finestrat is only a short drive. As an all round base Finestrat would likely be better.
