The High Cascade Mount Bachelor loop consists of wide snowmobile singletrack, some doubletrack, Edison-Lava Tr31 and Metolius-Windigo Tr99.
This route has sometimes been used as Loop 1 of the High Cascades Wild 100 race.
As with the Edison-Lava Tr31 ride, the best ride profile occurs when the loop is best started from the Lava Lake campground.
Starting the CCW loop from the Lava Lake campground gets the big Kwolh Butte-Tot Mountain saddle ascent over in the first 7mi.
This is followed by the Dutchman Creek ascent, a moderate 3mi, 800' climb to the Dutchman Flat TH area, then 15 miles of downhill back to Lava Lake. Epic stuff.
Starting from the Lava Lake TH, and sometimes approached from Sparks Lk Tr4, a 17mi (1600' ascent) Metolius-Windigo Tr99 - Quinn Creek Tr1 lollipop provides the best ride profile when started from the Lava Lake TH.
