Read reviews on TA and decided to go quad-biking. Palmaquad seemed to be the go to choice. Had initially made a reservation with them, but had to cancel last minute. Decided to go with Diana Quad instead as they were willing to negotiate the price. There were three people in our group and I think we settled for 200 Dh for an hour ea. One of the guides came to pick us up from the market we were at in a pink van, which was amusing. On the way we passed up the big Palmaquad setup and wondered if we made the right choice. We were shown our rides and given helmets (which were not in the best shape). Our guide took us along the beautiful shores and through some dunes. It was going great despite the fact it was a little chilly and we were bundled up. After about 45 mins we stopped and renegotiated for another hour to go deeper into the dunes. This was the most fun part. It was just the three of us and the guide (ahmed) and we were whizzing up and down dunes! it was so exciting. Our guide helped us out whenever we got stuck and let us explore on our own to take pictures etc. We saw a big group of palmaquaders in their 'uniforms' going behing each other in a line escorted by a guide at the front and the back of the line. This was while we were freely rolling up and down steep dunes multiple times! Glad we didnt get stuck on the big group which didnt seem to be doin exciting moves. So if you are ready for some serious fun and dont mind not having state of the art equipment, Diana Quad is no doubt the better choice!
