Snorkeling near Valencia?
 

Anyone have experience snorkeling near Valencia?

I've read there are a couple great areas for it in the area, but what I'm having trouble finding is an easy way to do it. We are one experienced snorkeler and one novice (but an expert swimmer) and I'd like to find an outfit that both rents gear and does tours out of Valencia as we won't have a car.

Suggestions?

I have a friend who's a professional diver (has all the gear) so have never rented equipment.

Tabarca (close to Alicante) is a well known spot and this company provides the gear and the means to get there
