This should have been fun but the toboggan directly in front of us hit the wall of a house and one of the passengers panicked and jumped out. As the toboggan had not quite come to a standstill she sprawled over the road, breaking her camera, gashing and bruising her leg, and we later discovered she had broken her wrist. The toboggan operators took her to hospital and replaced the camera.
If you are a little unsteady on your feet or elderly, consider doing this ride very carefully before you embark on it.
This tour could be done independently for less expense. Rent a car or taxi. Go in the morning, do the camel ride first (pretty tame in the excitement stakes but fun for 8 euros per person) and then whip along to the Timanfaya National where you pay 8 euros per person to take a 1 hour recorded narrative tour of this fantastic volcanic area.
