Hi Rich
Valencia isnt really my patch, there are a few dive centres if you type " Buceo Valencia" into Google youll get a ton of answers.
I´ve just had a quick look a few run trips to Benidorm, well there is the island and not much else worth diving and its a fair way from Valencia.
Try and get to the ISLAS COLUMBRETES they are quite good, having said that its a good 5 years since I've been
Salidas Bagua
Try and stay away from the Ebro delta nil viz !
If you fancy comming over to the Atlantic we are in Galicia and can sort dives out for you. There is pleanty to dive and rearlly get blow out. We also run trips to the deep wreck of Finesterre. We are hoping to get our new website up and working by next week.
Also there are a few lads that travel down to stay with us from Madrid so suggest that you e-mail me from Madrid and see if car shareing is an option.
Another option is that a new fast train the "AVE" has just last week been inorgurated and this will give you fast access to the coast.
If you need any help PM me
Cheers
Chris
