If you are looking for more passes before the bigguns are opened later this month, the Sörenberg south of Lucerne was nice yesterday. We did a full route from Thun to Lucerne on the touring bikes, climbed around 1600m and covered 118km. We were above the snow line for the pass itself, but the road is cleared.

Warning - section betwen Schangnau and Südelhöhe has offroad/gravel track sections and is unsuitable for road/racing bikes. Route 4 provides a suitable detour to avoid this.
