Switchback do all mountain holidays may-sept in bubion, and DH from oct to epril. I think there is some latitude with the dates. Best to email Mike @ switchbacks and ask. The Am is higher in the mountains where it is cooler in the summer. The Dh is on the foothills which are great in the winter. I’ve had rain there once, it evaporated as it hit the ground, and made the sand really grippy.
I’ve done the Dh trip 4 times, and am doing the AM later in the year.
The DH is brilliant, challenging trails, good guides, lots of fun.
The Am I have only heard about from the group I go with, but they all have really good things to say about it.
I can only give positive feedback, Mike is a top bloke (ex DH pro racer form the 90’s) and all the guides are excellent.
The accomodation style varies. They have the switchbacks villa, where I have never stayed, and then they just rent apartments/rooms as and when they need them. Discuss with Mike what you want, although that does not garauntee a choice..
