Mt. Princeton Road Trailhead
3 (0=Paved, 6=Very Difficult 4WD)
2WD dirt to the lower TH.
4WD access to 12,000'.
From Buena Vista: From the center of town, drive west on the County Road (CR) 306 for 0.7 miles. Turn left on CR 321 and continue south for 7.2 miles. Turn right onto CR 322 at a large sign.From South of Buena Vista: Over 5 miles south of the U.S. 285 / 24 junction, turn west on County Road 162 in the town of Nathrop. Drive over 4 miles to a junction. Turn right on CR 321. After 1.2 miles, turn left on CR 322.
On CR 322, drive 0.8 miles and turn right into the Mt. Princeton trailhead. This trailhead is at 8,900' and there is a large parking area. If you have a good clearance 4WD, you can continue up the Mt. Princeton 322 road but BEWARE, it is narrow with few pull-offs and trying to pass oncoming vehicles on a busy weekend can be very frustrating. Follow the signs for the Mt. Princeton trail and start up the road. Drive/walk 3+ miles to the radio towers at 10,800' where you'll find parking for a couple of vehicles. Turn left and continue on the 322A road. At ~3.3 miles and near 11,000' reach a few small pull-offs with space for 5 or 6 vehicles. Not much room to set up tents but ok for vehicle camping. Beyond here the road gets more difficult and parking becomes scarce.
Closed at the lower TH.
Parking: Large parking at the lower, 2WD trailhead. A few vehicles can park at the radio towers. A few vehicles can park in the pull-offs just up the road from the towers. Above that, not much.
Camping: No camping at the 2WD trailhead. No camp spots along the 4WD road until you get above the radio towers, then you'll find a few small pull-offs.
