I've been out to Switchbacks 3 times and wouldn't think of using anyone else for that area, not that I've heard many horror stories about the other operators, just that I get on well with Mike and the other guides, they have a nice laid back attitude, will tailor your trip to suit your needs, wants and ability, they'll push you if you need it and coach if you want it.
Bubion is a great base, plenty of variety in food and drink, and the locals are friendly to bikers.
The trails are fantastic, generally very technical but with great variety, fast, flowing,swoopy, steep, rocky, drop offs, loose, dusty, drifty, pick any combination! and then there are the switchbacks…
Last time I was there we rode every day for 14 days straight, best bike trip ever
I'll be back again this autumn
