Info: Road open and passable for high clearance except for the last 0.3 miles to the Reservoir. Quite a bit of a crowd up there this weekend, mostly 4-wheels and ATVs, and shooters. The place is trashed out already, which was unexpected this early in the season, I hate to see a beautiful place trashed this way...

Info: Rainbow road in good condition all the way to the Fall River Reservoir gate.

AVOID the Mackinaw Lane "shortcut", Google Maps took me this way and this road is barely passable in a small (short wheelbase) 4WD vehicle using low gears and select tire placement.

Info: For what it’s worth, I made it 1.5 miles in Henry the Camry. It would have been mostly passable to that quasi-parking area about another 1/4-1/2 mile up, but there was enough spice before that to make me glad I parked at 1.5 miles. Any decent 4WD should have no problems, tho.

Info: Road is quite rocky, would recommend high clearance 4wd. Only saw jeeps/trucks/similar at the lake. Probably could get a Subaru 1/2 to 2/3‘s of the way up the road.

Info: I was able to get my Subaru Forester to the Reservoir. The last 2 miles were bumpy. I didn‘t see any low clearance 2wds at the reservoir, but there were a few that made it to various points on that last 2 miles.

Info: This trailhead is for access to Fall River Reservoir and Chinns Lake. Unofficial trailhead for Parry Peak, Mt. Bancroft and Mt. Eva.(13ers). Dirt road is now snow covered but driveable with a good 4 Wheel Drive and good tires. It is starting to drift so it is possible to get stuck.
