Planning next years euro trip and it seems like I'll be able to get some time in the Dolomites late july and it is time to lock in some places.

I think I'll be able to get one day dedicated to MTB and after a little bit of googling it seems like the thing to do is Sella Ronda.

A couple of questions to anyone who has done it.
1) Is Sella Ronda the thing to do or are there more scenic / better tracks in the Dolomites
2) As I understand it, it is a guided tour going up in gondolas and down on two wheels - right?
