60 free Rocky Mountain National Park trivia questions with answers — geography quiz, new questions added Aug 2026.
This Rocky Mountain National Park trivia quiz covers the Colorado park that straddles the Continental Divide an hour and a half from Denver, with 60 peaks over 12,000 feet, the highest continuous paved road in North America and the headwaters of the Colorado River. It ranges across Trail Ridge Road, Longs Peak and the Diamond, the elk rut in Moraine Park, the tundra above tree line, and the towns of Estes Park and Grand Lake at either gate. There is plenty of history too: the Ute and Arapaho trails, Stephen Long's 1820 expedition, John Wesley Powell's first ascent of Longs Peak, the mining ghost towns of the Never Summers, Enos Mills' campaign for the 1915 park act, the CCC road-builders of the 1930s, and the nearby Stanley Hotel that gave Stephen King The Shining. Questions run from easy to expert with the difficulty shown on each one, so it works for a car game on the drive up from Denver or a serious park-nerd challenge. Every answer was checked against a reference page and each question carries its citation. If you enjoy it, try our Yellowstone, Grand Teton and US National Parks quizzes next.

Moose
Moose spread across the west side after their 1978 arrival and faced no predators in the park.
Q 14The old Indigenous ridge trail followed by today's high road, 'taienbaa', means what?

Colorado River
The road down the west side follows its North Fork through the Kawuneeche Valley.
Q 17What runs directly through the centre of the park, sending water either to the Pacific or the Atlantic?
The Continental Divide
In the Never Summer Mountains it makes a 6-mile horseshoe bend, so streams there flow the 'wrong' way.

Footsteps can destroy tundra plants that take hundreds of years to recover.

About 11,000 feet
Just below it, wind-stunted trees grow into dense mats that can live a thousand years.
Q 29What is the name for the stunted, wind-twisted trees that grow at the tree line?
Krummholz
Seedlings sprout in the lee of rocks and grow only as high as the rock shelters them from the wind.
