Roadway & Traffic:
The roadway is in excellent condition throughout the climb. Traffic is mild and not a concern. Road is snowed in and closed to all traffic usually from sometime in early November into late May. Be sure to check the NPS website for road closure information if planning on riding in spring or fall.

There's plenty of parking in either the town of Grand Lake or within the national park along the route at trailheads, scenic overlooks, etc.
There are scenic overlooks with restrooms but otherwise the climb is unsupported.
Before heading out on any cycling adventure check out our Things to Bring on a Cycling Trip and use our interactive check list to ensure you don't forget anything.
Grand Lake is an awesome rocky mountain town to stay in, but our favorite place to stay is in Estes Park due to its proximity to Boulder, Denver, and the other climbs in the Front Range.

Cycling Trail Ridge Road from Grand Lake (west)

Ride 21.7 miles gaining 3,720’ at 3% average grade.

Although this climb is a robust 21 miles, it is less than one-half the length of Trail Ridge East which at 44 miles is the second longest bike climb in the US and sixth longest in the world.   

Because there are 2 ½ miles of flat/rollers past the finish of Trail Ridge West and the finish of Trail Ridge East, the finish for each are in different locations.

Before heading out to ride Trail Ridge West, be sure to rely on our list of Things to Bring on a Cycling Trip, and use our interactive checklist to ensure you don't forget anything.

When to Climb Trail Ridge by Bike:  This bike climb tops out above 12,000’ so it is best to do it between June and September.  Trail Ridge Road does close during the winter:

“It is open to vehicle traffic roughly from Memorial Day weekend in May through Columbus Day in October. Temporary closings may occur in early June or late fall because of snow. Occasionally it opens earlier in May. Average close date is October 23 (latest close date Dec. 2, 1933) when the Park Service gives up fighting the snow and turns the road back to Mother Nature for the winter. During winter  it is closed between Many Parks Curve and the Colorado River Trailhead.  Call  (970) 586-1222 anytime for the latest Park recording of the status of the road”  (Rocky Mountain National Park).  

Though we’d say that the best months to ride Trail Ridge are June to September, there are never any “guarantees” . . .
