The Rocky Mountains

The Rocky Mountains

Glacier National Park had 26 named glaciers in 1966. It has 10 today. Scientists project most will be gone by 2030. That ecological fact is worth knowing before you arrive, because it changes what you’re looking at: not a permanent landscape but one in slow-motion departure, and the visitors who understand that tend to pay a different kind of attention.

The Rockies stretch roughly 3,000 miles from northern British Columbia to New Mexico, covering terrain that runs from dry high desert in the south to glaciated alpine wilderness in the north. They’re too large to visit as a unit – what you’re choosing is a region or a park, and that choice matters more than most people realize when planning a trip.

Colorado

Rocky Mountain National Park, centred on Estes Park, is the most visited unit in the state and deserves the reputation. Trail Ridge Road crosses the continental divide at 12,183 feet, the highest continuous paved road in the US, providing access to above-treeline terrain without serious hiking. The elk in the Kawuneeche Valley during September rut are genuinely spectacular – the bugling carries across the meadow in a way that no recording quite captures.

Timed entry permits are required from late May through mid-October 2026, between 9am and 2pm daily, with Bear Lake Road corridor requiring a separate reservation. Permits cost $2 per vehicle and are released on recreation.gov on the first of each month. Book early; popular slots go fast.

Colorado’s mountain towns run a spectrum worth thinking about. Aspen is beautiful and expensive in a self-conscious way. Telluride, more remote, feels more genuine. Ouray, a Victorian mining town in a canyon box at 7,760 feet, is perhaps the most immediately likeable – walkable, uncrowded compared to the others, surrounded by good hiking and a world-famous ice park in winter. You could do worse than spending three days in Ouray and skipping Aspen entirely.

Wyoming: Grand Teton and Yellowstone

Grand Teton National Park has the most photogenic mountain range in the lower 48. The Teton skyline rises without foothills from the Snake River plain – the abruptness is the whole effect – and the view from Oxbow Bend early morning with Mount Moran reflected in still water is one of the canonical American landscape images. It earns every repetition.

Yellowstone sits directly north and is almost always combined in an itinerary. The geothermal features – Grand Prismatic Spring with its vivid orange and yellow bacterial mats, Old Faithful, the sulfurous mud pots along Fountain Paint Pot Trail – are genuinely unlike anything else. The wildlife calendar adds considerably: bison herds crossing the road and causing backups, wolves visible in the Lamar Valley at dawn, grizzlies in the meadows below Dunraven Pass. Crowds in July and August are severe. September is significantly better.

Montana

Glacier is the least-visited of the major Rocky Mountain parks and arguably the most spectacular. In 2026, Glacier has shifted its vehicle management approach: rather than a vehicle reservation system, the park is piloting a ticketed shuttle system requiring visitors who spend more than three hours in the park to book shuttles to the Going-to-the-Sun Road alpine area. Shuttles depart from west and east entrances. Book through the park’s official website before you arrive; demand is high and walk-up seats are limited.

The Going-to-the-Sun Road itself, 50 miles of engineering through mountains that didn’t want to be crossed, remains one of the great American scenic drives. The Logan Pass area sees the most wildlife; mountain goats are almost guaranteed.

Skiing

Winter access runs on different logic. Vail, Aspen Mountain, and Park City in Utah are the premium options for people who want resort infrastructure. Jackson Hole in Wyoming has the most serious terrain – Corbet’s Couloir is the test piece, the rest of the mountain is no joke either – and a mountain atmosphere that hasn’t been entirely manufactured for tourism. Snowbird and Alta in Utah’s Little Cottonwood Canyon combine extraordinary snowfall totals with prices that undercut Colorado alternatives by a meaningful margin.

Getting Around

The Rockies essentially require a car. Denver International Airport is the most convenient entry for Colorado; Salt Lake City for Utah; Bozeman for Montana and the northern parks; Jackson Hole Airport for Wyoming. The Jackson Hole airport sits inside Grand Teton National Park, the only commercial airport in a US national park, which makes it convenient and expensive in roughly equal measure.

Practical Notes

Altitude affects everyone differently but affects most people arriving from sea level. Headaches and fatigue at 8,000 to 10,000 feet are common for the first day or two; stay hydrated and don’t schedule your hardest hike on day one. Mountain weather moves fast; clear mornings can produce afternoon thunderstorms within an hour. Don’t be on exposed ridgelines after noon in summer.

Bears are present throughout – black bears across the range, grizzlies in Yellowstone, Glacier, and the Tetons. Carry bear spray and know how to use it before you need it.
