Use this trailhead to access the following summits from the west side of Independence Pass: Grizzly, Garfield, UN 13,460, UN 13,090, both Truro summits, UN 13,631, and Petroleum Peak, all of which are located south of Grizzly Reservoir. The trailhead for Tabor Peak can be accessed from the same 4WD road up Lincoln Creek before reaching the reservoir. Same for the New York Creek/Peak TH. The coordinates provided above are for the Portal Campground located by Grizzly Reservoir. This location will serve as the trailhead.
From the Town of Aspen, drive east up state highway 82 toward Independence Pass. Two miles past the turnoff for the Weller CG, or one mile past the Grottos TH, turn south (right) and drive down toward the Lincoln Gulch Campground. There is an information kiosk right off the highway and a mileage sign for locations along the Grizzly Reservoir/Lincoln Gulch road. Coordinates for this turnoff are: N 39° 07' 10.50" W 106° 41' 18.27". The road immediately crosses the Roaring Fork River. If in a passenger car, you'll need to park either at the kiosk or down at the campground. If you have a 4WD or a better clearance type vehicle, then the road to Grizzly Res. turns off to the left shortly before reaching the campground. The road is rated "4WD." There is a sign indicating the campground is straight ahead with a Forest Service gate. The road to Grizzly "appears" to be in better condition than the one to the campground, but the short road down to the campground is still passenger vehicle passable.
If coming from the Front Range, drive to either Leadville or Buena Vista and turn onto SH 82 from US 24 at Twin Lakes. Drive up and over Independence Pass. On the west side of the pass, drive on past the Lostman CG, and in just under 4 miles past that campground will be the turnoff for the Lincoln Gulch CG. on the left. 4WD or vehicles with better ground clearance may then continue ESE for Grizzly Reservoir as described above. This road is identified as CR23 or FS107.
Along the first 3 miles up to the New York TH, there are 22, designated, primitive campsites with bear-proof lockers for food storage. The road tends to be slow going with potholes, etc., but no real major obstacles. At times, you'll be driving over slabs of rock, but clearance is usually not an issue. We drove the first 3 miles of this road in 2019. While there was one area of extensive avalanche damage and another smaller area, both at about 2 miles in, both had been cleared. It may take over a half hour to drive the 6 plus miles back to the reservoir if going that far. There is a small campground there with toilet facilities called the "Portal" campground; first-come, first served.
The trailhead for New York Creek/Peak on the mileage sign mentioned above is 3.3. We measured 3.1. If using that trailhead, the turnoff will be on the right and if you drive a short distance down through some overhanging willows, there is a large parking area with lots of cobbled rock. There is no bridge to assist crossing the creek here. Coordinates are: N 39° 05' 39.23" W 106° 39' 35.51". Elevation 10,100 ft.
The trailhead for Tabor Creek is another 1.8 mile past the signed trailhead for New York Creek/Peak. Coordinates are: N 39° 05' 33.11 W 106° 38' 39.81". Elevation 10,290 ft. There is no bridge to assist crossing the creek. Be prepared to wade.
There are two designated Forest Service campgrounds: The Lincoln Gulch CG and the Portal CG at Grizzly Reservoir. In addition, for the first 3 miles as you drive SE to Grizzly Res., there are numerous (22?) "designated" primitive spots for camping. These have been marked by the Forest Service. On summer weekends, both campgrounds and all the designated primitive spots can be fully occupied. Seems to be a very popular area. If the road is open south of the Portal CG, there may be some other, usable primitive sites. Both the Portal and Lincoln Gulch CG have vault toilets, but neither has water. Both have only about 6 sites. The Lincoln CG, you could get an RV or trailer down into, but not the Portal.
