The old railroad grade over Rollins pass from Rollinsville to Winter Park.

Alan Doak


Needle Eye Tunnel is closed and barricaded, but a detour path over the tunnel is available.


Head up the smooth dirt East Portal road from Rollinsville. This part of the road is suitable for all cars and crowded, so many people drive this section and park at the Moffat Tunnel. Check out the Moffat tunnel, which made the original narrow gauge railroad obsolete, before heading up the switchbacks leading up to the continental divide. There is also a bore parallel to the Moffat Tunnel which pipes water from the west side of the divide to the east side, confusing the traditional definition of a continental divide as the division between 2 drainage basins.

As you near treeline, you'll encounter the lovely Yankee Doodle Lake and Jenny Lake. On the east side of Yankee Doodle lake is the Boulder Wagon Trail, which is how 4WD vehicles avoid the Needle Eye tunnel (which is closed and barricaded). But on a bike, there is a clear detour trail over the tunnel.

At the summit, there are a few ways to go, but they all merge back together again before heading down the west side of the continental divide. If you stick to the railroad grade, near the summit is the trestle bridge, which is quite a thrilling crossing. You'll also notice a large number of timbers next to the grade near the summit, which are the remnants of a near continuous snow shed.

Enjoy the pleasant downhill on the West side of the continental divide, while stopping occasionally to enjoy the view and to inspect relics of the railroad. Pop out onto Highway 40, and either cross the highway or ride the shoulder west a bit to access the Fraser River Trail which leads to either the town of Winter Park (West) or the ski resort (East) for food and drink.

The rain made for fun conditions. 2 notable but short patches of snow, 1 a little before the tunnel and 1 right at the Rollins Pass gate.

As of June 25 2017, the trail is still impassable. Less than .5mi from Yankee Doodle Lake, the trail is snow covered and not clearing soon. 20mi — 2h 00m

Worth doing, but I'd say this is a one and done type ride. Bring a patch kit and and tube since it's mostly chicken heads the whole way up. As said below it's popular with 4x4's so expect to eat some dust. Great views so it's worth doing at least one time. For full effect you can have someone shuttle you from WP. Apr 11, 2017
This a great high altitude ride, not physically or technically hard - you just need to deal with thin air. Note the gpx file does not take you over the ionic trestle bridges which are a highlight of the ride. Check out a map before you ride so you can find your way to the trestles. Make good use of the earned gravity and ride the single track system back to Winter Park - Yankee Doodle is fun! Aug 6, 2017
