If you turn north off the honey road at Tamazirt you are signposted to Grotte Winimidouine. You take the road for about 8km and then come to a car park. The drive is very picturesque and worth the trip in itself. There is then a piste track uphill, seemingly leading to the top of the mountain and far distance but actually only for about 500m. There is then a last scrambly bit and you are at the Grotte.
There is an artificial pool ouside the entrance which makes a good place fo a picnic and the water is invitingly clear for a swim in summer. you can't go very far into the cave itself as there is a safety gate at 20m. There is a man brewing mint tea and he will give you a cup, tell you of the cave and show you a map of them. It is a major extensive cave system extending for 19km but most of it is flooded and so best left to cave-divers but for them it would be a great expedition.
