The barbecue pit at Timanfaya National Park in Lanzarote has to be the ultimate barbecue experience - this stone well sits above a vent in the ground which cooks the meat on the grill. If you dare to look into the well, you might catch a dull red glow a few feet down.

The restaurant features a few other neat tricks as well - volcanic shafts which shoot columns of steam into the air, and another stone well outside that can ignite dry grass in seconds. It just shows that a few feet under the surface, the effects of volcanic activity on Lanzarote can still be felt.
