+1 for Colorado. We were “self guided” (actually an ex-pat riding buddy who lives in Boulder hosted us). Not sure you need a guide in CB, the trails are waymarked and established enough to feature in cheap guide books.
winter park worth a trip too. The DH courses are shallower grade and more flowing and natural then alps stuff (less vertical drop so they have to work it, feels more like a downhill XC route), and some cool XC routes in the valley (we did a long one that ends in WP that is used for an annual race, cant recall name at the mo).
Whats that, pictures you say? 😀
