For the first time, we went diving in Lanzarote during october school holidays.
In fact, our diving club L.A.C. (Liancourt Aqua Club) organized a quite cheap diving week for those who wanted to participate.
After flying in from Paris Orly, we landed in Lanzarote, had a small briefing in the evening on how the diving would be organized, and went for it. In short, we had 2 dives in the mornings 9h to 13h (with break), and in the afternoon we were free to do as we please.
We had mostly 2 group of divers. One group was supervised, as the divers had only their level 1 license and weren't allowed to go deeper than 20m. The rest could go at least to 40m, and some even had the license to die alone at 60m (as per our diving instructors told us while signing for our level 3 license).

The underwater landscape was amazing. As Lanzarote is composed of around 300 volcanoes, the underwater landscape was in par. We did dive in shallow waters as in deep waters (going down to 48m), did visit some old ship-wrecks, and some caves just because we could. Went to water from stairs, boat, or just jumped in. Check out the videos we did on Youtube: My video, and the Video of a diving friend.

Because, as all divers know, our nitrogen levels were too high to take a plane right after diving, the last day had to be spent on land.
2 spots that anyone on Lanzarote should visit are: the "national parc of Timanfaya", which is the the landscape saved from human intervention since the big eruption of 1730, and the site called "Jameos dela agua". Both truly awesome!
