Alcalali is nice, very little shade so take plenty of water etc there are shops on the way but nothing nearby.
Guadalest is amazing, one of my favourite areas, there are plenty of mixed grade sport routes to go at and if you fancy some lower grade trad there are a couple of really interesting routes at the lower crag (Esters chimney S4a- 4 pitches) easy but great fun!! (www.compasswest.co.uk) nb Lower crag is not covered by the rockfax guide, its less travelled but fun, some polish in areas.
Sella is great and accessible but as already advised the car park area is polished, but there constant new routing in the area so ask either Tony or Kristina at Costa Vertical and they can advise, they live in the house above Sella. Also The Orange house hostel in Finestrat (on the way to Sella) is always worth a visit to chat with Richard and Sam the owners, they've been in the area for around 20+ years and Rich has bolted a considerable amount of routes at all areas (Font of knowledge) Parle 6a+ is his route and Magical mystery tour 5a , both in Sierra de Toix are popular, I've only done the latter so far.
Climbing stores- Decathlon in Finestrat or La Gruta in La Nucia........Lots of new and more current guides have been published in the last 12 months La Gruta stock them! Rockfax were out at the end of last season in view to updating their current guide so there is new stuff to go at that their current edition doesn't cover.
Either way, its a beautiful areas as soon as you leave the large towns it is anyway, enjoy!!!
