Gives a couple of ways to get between the Adige river valley and the main pass to the "heart" of the Dolomites -- which avoid some of the higher-traffic sections of roads. Also the road through and above Steinegg is rather pretty -- I'd ride from Bozen up to the ridge above Steinegg and go back the same way just for fun even if I didn't care about getting to the Karerpass or the Dolomites. To me the key is to avoid the long tunnel at the bottom of the Eggental road (even though it's closer to Bozen). The only disadvantage to going through Steinegg to the Karerpass is that you end up on the main Eggental road anyway -- but higher up where it has less traffic. And the bike path from Bozen to Blumau is kind of interesting in itself. This route not checked by me since 2008.by AmericanTourist
