Do you have any advice for potential travellers?
Wheeled luggage will make the trip smoother especially when using public transport.
For the Christmas/New Year trip be prepared for it to possibly be very cold at times. Take extra clothing with you on the transfer to Granada. A sleeping bag would be useful in the Gite at Tachddirt, it is at 2341 metres and apart from a brief fire in a communal area it is unheated.
Good walking shoes/boots for the optional walk from the Gite.
If you might be travel sick in a minibus going up and around a lot of tight corners, then the journey to the Gite might be best approached with some pharmaceutical assistance.
