The Costa Blanca has long been a tourist destination so there are numerous other activities that you may which to consider. This page will hopefully give you some ideas and details.
There are a number of canyons that can be descended on the Costa Blanca. Check out the Canyoning page for details.
There are a number of spectacular scrambles in the Costa Blanca so check out their details on the Scrambles page.
Believe it or not there are now a couple of Via Ferratas on the Costa Blanca. Check out the details on the Via Ferrata page.
I have received several enquiries about walking in the Costa Blanca and although I have not walked myself I have gathered a few details.
There are a couple of guidebooks to the area:
There is an accompanying website, Costa Blanca Mountain Walks, written by the author himself. This contains interesting introductory pages on the Costa Blanca and its mountains as well as a couple of example walks and an updates page for those things that have changed since publication of the books.
The Hedera Helix website has some useful write ups of walks from the first book to allow you to judge for yourself.
You can buy maps of the area from the Map Shop website. They stock both 1:50,000 and 1:25,000 scale maps for the whole of the Costa Blanca area.
At the moment I have few details on mountain biking on the Costa Blanca although I do know that the Orange House hires out bikes, helmets, etc and is starting to compile a guide to rides in the area. Check out their Mountain Biking page for further details.

The Costa Blanca is made up of limestone so is riddle with the inevitable caves. There are many holes, that as an ex-caver, have beckoned to me as I climbed in various areas.
I have received an email from a local caving club that are open to visitors. They are based in La Vila Joiosa (Villajoyosa) which is just 10km South of Benidorm. Here are their details:
They don't have a website yet so if you want any further details you will need to email them.
