Colorado National Parks Road Trip: All Four in Nine Days
Four parks, four corners of the state, about 1,000 miles as a loop from Denver. Rocky Mountain is 70 miles northwest of the city and needs three days. Black Canyon of the Gunnison is a half day of overlooks and one steep trail. Mesa Verde needs a full day and a ranger tour ticket. Great Sand Dunes needs half a day, or a full one if Medano Creek is running in late May and June. Nine days is comfortable, seven is tight, and the season that works for all four is June through September. Our Rocky Mountain National Park itinerary covers the biggest leg.
The four parks, and how long each needs
- Rocky Mountain, three days. The Bear Lake corridor for alpine lakes, Trail Ridge Road for the tundra, and one big day on Longs Peak or in Wild Basin. Timed entry has applied in summer, so read the timed entry rules first.
- Great Sand Dunes, half a day to a day. The tallest dunes in North America against the Sangre de Cristo range. Climb High Dune, and in late May and June wade Medano Creek at the base. Sand gets to 150F on a July afternoon, so go early or late. See Denver to Great Sand Dunes.
- Mesa Verde, one full day. Six hundred cliff dwellings, and the good ones (Cliff Palace, Balcony House, Long House) are ranger led tours you buy ahead. The Mesa Top Loop needs no ticket.
- Black Canyon of the Gunnison, half a day. A gorge 2,000 feet deep and in places only 40 feet wide at the bottom. South Rim Road with its 12 overlooks, and the Warner Point trail. Descending into the canyon is unmaintained scrambling and needs a permit.
The nine day loop from Denver
- Days 1 to 3, Rocky Mountain. Ninety minutes from Denver to Estes Park. Emerald Lake and Sky Pond, then Trail Ridge Road to the Alpine Visitor Center at 11,796 feet.
- Day 4, over the divide. Estes Park to Gunnison or Montrose, five hours through Leadville and Buena Vista. One of the best driving days in the state.
- Day 5, Black Canyon. South Rim overlooks in the morning, then two and a half hours southwest to Cortez.
- Day 6, Mesa Verde. A cliff dwelling tour, the Mesa Top Loop and Petroglyph Point.
- Day 7, Durango and the San Juans. The Million Dollar Highway between Durango and Ouray is 70 miles and takes three hours, and it deserves the day.
- Day 8, Great Sand Dunes. Four hours east over Wolf Creek Pass. Dunes in the late afternoon when the sand has cooled.
- Day 9: four hours back to Denver, with a stop at the Bishop Castle or Royal Gorge if you have children in the car.
The seven day version
Drop the San Juans day and shorten Rocky Mountain to two days. You keep all four parks and lose the two best drives, which is the wrong trade if you have any choice. A better seven days: Rocky Mountain for three, Great Sand Dunes for one, and three days in the San Juans around Ouray and Telluride, treating Black Canyon as a morning on the way.
Altitude, which is the real planning problem
Trail Ridge Road tops out at 12,183 feet and the Alpine Visitor Center car park sits at 11,796. If you fly into Denver at 5,280 feet and drive straight up there, you will feel it: headache, breathlessness, poor sleep. Two rules that solve most of it. Sleep the first night in Denver or Estes Park at 7,500 feet rather than higher up, and save Trail Ridge for your second or third day rather than your first. Drink more water than feels necessary, and treat any 14,000 foot summit as a day four objective at the earliest. Our Colorado 14ers guide has the acclimatisation detail.
When to go
- June to September for all four parks. Trail Ridge Road usually opens by Memorial Day weekend and closes in mid October.
- Late May to mid June if Medano Creek at Great Sand Dunes matters. The flow depends on the snowpack and it is gone by July most years.
- Late September for aspen gold in the San Juans, which is the best week of the Colorado year and the busiest.
- Afternoon thunderstorms build almost daily in July and August. Be off any exposed ridge by noon.

Colorado National Parks Road Trip: All Four in Nine Days FAQs
Four: Rocky Mountain, Great Sand Dunes, Mesa Verde and Black Canyon of the Gunnison. The state also has eight national monuments, including Colorado National Monument outside Grand Junction and Dinosaur on the Utah border.
Yes. A loop from Denver runs about 1,000 miles and works in nine days. Seven is possible if you cut the San Juan Mountains day and give Rocky Mountain only two days.
About 235 miles and four hours, south through Colorado Springs and over Poncha Pass. It pairs naturally with Mesa Verde and the San Juans rather than with Rocky Mountain.
For the cliff dwelling tours, yes. Cliff Palace, Balcony House and Long House are ranger led and ticketed, and they sell out in summer. The Mesa Top Loop drive and Petroglyph Point trail need no ticket.
Usually by the end of May, and it closes in mid October. Exact dates move with the snowpack every year, so check the park road status page in the week before you drive it.
Rocky Mountain, because it is 90 minutes from Denver and holds alpine lakes, tundra driving and 14,000 foot peaks in one park. Great Sand Dunes is the better choice if you want something you have not seen before.
