Big Thompson Canyon (CO Highway 34) is the most direct route from the north Front Range (Loveland & Fort Collins), and is spectacular - you sometimes spot Rocky Mountain Sheep on the steep canyon walls as you follow the river's steep descent from the high mountains. US Highway 34 from Loveland and I-25 to Estes Park and Rocky Mountain National Park will remain OPEN through the summer of 2016. Road construction and major projects will not begin until after the first weekend in October 2016 (specific date has not yet been determined). Travelers on the highway from August to October 2016 may encounter short delays (up to 20 minutes) associated with early project work. You can check with the CDOT website for the latest construction & travel info.
Highway 36 through Boulder & Lyons is the most direct route from the south Front Range. It was extensively rebuilt after flooding. Take either 36 or 34 when coming from DIA.
Approaching from the West side or I70 to the south via Highway 40, you will arrive at Grand Lake, Colorado by turning north on Highway 34.
The Peak to Peak Scenic Byway is a scenic route for driving to Rocky Mountain National Park from the South side. You will head north from Interstate 70 at Exit 243 and follow Hwys 119/72/7 to arrive at Estes Park, Colorado.
The Peak to Peak Highway (119 to 72 to 7) runs north-south from Estes Park to I70 and is a favorite scenic drive - especially during fall colors.
Trail Ridge Road (Highway 34) connects the two sides of the Park, crossing the Continental Divide at 12,183 ft. It closes during fall snows, and permanently for winter when snowfall can no longer be cleared - usually in mid-October. It typically opens late May.
