This trail is best done downhill, as mapped here. To get to the start, either take Beaver Lake Trail
, or better (and longer), take Cinch
to Allie's Way
You start on what must have once been a road, but is now a wide singletrack on a bench cut through aspen groves. It's very smooth and peaceful. It then curves around and crosses a few ski runs and climbs up just a bit through a few switchbacks.
More aspens... more ski runs... and then a residential area with a few road crossing that are all well marked. There's a tiny detour to a picnic table with a great view of the valley far below.
Now you're in Bachelor Gulch and travel over a raised wooden platform over a boggy section. Continue on to the Arrowhead ski area and it gets noticeably drier and the views turn more to the west.
Once at the west end of the ski area, you have finished over 5 miles of flat riding and now descend a long way all the way to the base of Arrowhead. It's relatively steep, but the switchbacks are very wide and the surface is nice and tacky. Dowhill will be fine for beginners, but it might be a tough uphill if you're not used to the altitude.
