We booked the half-day quad biking at Lake Takerkouste for my partner's 40th birthday as a surprise. The enquiry and booking were handled brilliantly and we were given plenty of information and support to ensure we met the transfer driver who collected us from our Riad in the heart of the Medina.
The 4x4s were new, clean (as clean as they can be in a desert) and powerful. We were given all the equipment we needed and the four of us had our own guide who led us off through the low hills and desert landscapes around Marrakech. Not sure we ever saw Lake Takerkouste (!) but that didn't matter.
We had an amazing time, took in some great scenery and stopped for tea at a local berber village to clear some of the dust from our throats mid-way. Worth taking a silk/thin scarf to wrap around your face under the helmet - definitely keeps the sand out.
Half-day is fun but quite challenging in some places - the terrain is as rough as you'd expect. Not sure I would want to ride a quad for a full day.
