The Overview

Melbourne-based skier and snowboarder with 50+ resorts across 5 continents. Specialises in Australian resorts and international resort comparisons.
Keystone's summit reaches 12,408 feet, dropping 3,128 vertical feet to a base at 9,280 feet across 128 runs spread over 3,148 acres near Dillon, Colorado. Terrain splits 41 per cent intermediate, 21 per cent each for advanced and beginner, and 17 per cent expert, with average annual snowfall of roughly 235 inches. The resort carries Epic Pass affiliation. Twenty lifts, including seven quad chairs and one gondola, serve the mountain alongside six six-person chairs, one triple chair and five surface lifts.
Keystone holds a distinctive place among Colorado resorts as one of the few offering extensive night skiing, alongside three distinct mountains, Keystone, North Peak and the Outback, that give the resort considerable terrain variety across a single connected area. This combination of night skiing and varied terrain has built Keystone's reputation as a genuinely family-friendly, accessible major resort.
Ketchum, Colorado was renamed Montezuma in 1867 following the discovery of silver in the area, and mining activity continued in the region for decades. Ralston Purina purchased land and developed Keystone Resort, which opened in 1970 as a purpose-built ski destination rather than a converted mining town. The resort expanded considerably over subsequent decades, adding North Peak in 1978 and the Outback in 1999.
Vail Resorts purchased Keystone alongside Breckenridge in 1996 from Ralston Purina's Ralston Resorts subsidiary, bringing both resorts into what would become the Epic Pass network. Adult daily tickets run from 129 to 209 US dollars.

When to visit Keystone
The 2025-26 season at Keystone ran from 24 October 2025 to 20 April 2026, a roughly twenty-six-week season supported by average annual snowfall of around 235 inches. Keystone traditionally opens earlier than many Colorado resorts, and this extended season reflects that early-opening tradition alongside reliable late-season conditions.
Midwinter, from December through February, typically brings the most consistent conditions across Keystone's three mountain areas. As an Epic Pass resort within the Vail Resorts network, Keystone draws substantial visitation from Epic Pass holders alongside families specifically seeking the resort's extensive night-skiing programme and varied, intermediate-weighted terrain.
Keystone's night-skiing operation, among the most extensive in Colorado, continues to draw strong evening visitation throughout the season. School holiday periods bring substantial family visitation given the resort's approachable terrain mix and dedicated programming. Weekend crowds draw heavily from the greater Denver metropolitan area.
Specific event programming beyond standard operations and night skiing is not confirmed in available resort information. Since Vail Resorts' 1996 acquisition, Keystone has continued building on more than five decades of history since its 1970 founding by Ralston Purina. The resort's three-mountain terrain variety and family-friendly character remain central to its seasonal appeal.

Getting there
Getting to Keystone, and where to stay
Keystone sits near Dillon, Colorado, with a base elevation of 9,280 feet and a summit at 12,408 feet across a 3,128-foot vertical drop over 3,148 acres in Summit County. This setting places Keystone within a short drive of Interstate 70, among the more accessible major Colorado resorts.
The town of Keystone and the broader Summit County region, including nearby Dillon and Silverthorne, offer extensive lodging, dining and services within a short drive of the resort. Keystone's own base village provides considerable on-site accommodation directly at the mountain.
US Highway 6 connects Keystone to Interstate 70, providing straightforward access for visitors travelling from Denver and the broader Front Range. Winter driving conditions on this route can include snow and ice, though the well-travelled roads are regularly maintained given the resort's status as a major Colorado destination.
Denver International Airport, roughly a 90-minute drive away, is the primary gateway for visitors flying into Colorado, with Keystone's relative proximity to Denver supporting substantial day-trip and weekend visitation alongside its considerable destination-travel visitor base.

Park City, Alta and Solitude are pencilled in for 20 November, Snowbird and Snowbasin for 27 November, and Deer Valley for 5 December. Eagle Point will stay closed after the Cottonwood Fire. A super El Niño is forecast, but the big snow is not expected until January.

Hintertux Glacier Opens for 2026-27 With 12 Kilometres of Piste
Hintertux became Austria's second glacier to open for 2026-27 on Friday 2 October, after the Pitztal Glacier. Twelve kilometres of piste are running around the Olperer and Gefrorene Wand, served by one gondola and two drag lifts, with the Betterpark also open.

Vail Resorts Counts the Cost of a Thin Winter as Pass Sales Slide Further
A historically poor western winter cut Vail Resorts' annual net income from $280 million to $147.5 million and skier visits by 13.4 per cent. Now 2026-27 pass units are down 12 per cent as of 18 September, worse than the 10 per cent flagged in spring. Vail blames the weather and thinks some buyers are simply waiting, and it forecasts a rebound if the snow behaves.

Arizona Snowbowl's $1 Lift Tickets Are Hard to Find, but $9 Days Are Not
Arizona Snowbowl advertised eight $1 lift ticket days this winter. Go looking and only three are showing - 10 March, 1 April and 10 April - so the rest may already have gone. The consolation is a calendar full of $9 days, including all but one day in April. Opening day is 20 November, weather permitting, and opening weekend is $19.

Whitewater Brings Its Short Side Inbounds, With Six New Runs for 2026-27
For years, Whitewater's Short Side was where you ducked a rope and hoped for the best: unmapped, ungroomed and unpatrolled. This winter it's inbounds. Six new runs of glades and fall-line skiing add 190 acres (about 77 hectares), taking the resort past 1,400 acres in total. F2 Logging spent a month in the trees to make it happen, and opening day is pencilled in for 4 December. Bonanza now needs less snow to groom, too.

September Dusting Hits Mammoth Mountain Six Weeks Before Opening Day
Mammoth got its first snow of 2026-27 on Monday 28 September - and promptly lost it by Tuesday morning. Barely an inch fell at McCoy Station, but with opening day pencilled in for Friday 13 November, it's the first sign the Sierra is waking up. Last year's date slipped from 14 November to 20 November, so nobody's booking flights on a dusting just yet. Here's where California's early openers stand.
