Thought I'd share an experience I had recently.
Just back from Lanzarote. Was staying in the South (Costa Teguise). Was desperately looking for a guided tour and these are the only guys who seemed to be doing this in the southern part of the island:

I did not get to ride with them (stretched my ankle) but would highly recommend based on the fact that they were ready to collect me AND were kind enough to store my bike in their shop for 8 days (poor logistics on my side) while I had not spent a penny with them.
From the biking standpoint I wish I was staying in Puerto del Carmen BTW.
Overall, it's really, really nice there. Not sure I even want to get out and ride now - the contrast is sort of too strong 🙂
P.S. There's also Evolution Bikes (Gavin) in Costa Teguise but he's recovering from operation now so cannot do tours for the time being. But nice shop for the advice if you need some.
Thanks for the link I was just about to post a thread asking about mtb on Lanzarote as going soon for a week .
stopping at Costa Teguise and and looking at maps it seems the north is best for mtb or am I wrong on that .
