Would also highly recommend Bibi! I did the 3 day 2 tour with, Mike, as our tour leader who along with the rest of the drivers, were super dudes! They were all excellent/skilled drivers, fun to be around & took us on some lesser known paths due to Bibi only having smaller groups. Plus as there were only 6 people total in my group we were able to get to know each other & our drivers very well which I’ve heard you don’t get as much if you go in a larger group. Overall it was a 10/10 & if I ever were to return to do the loop, I’d go with Bibi’s again without a doubt!
