The Overview
Michael Fulton
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.

Thredbo Is 'On the Table' as EVT Reviews Its Whole Business
Thredbo is officially 'on the table.' EVT Limited, owner of Australia's most decorated ski resort, has hired Rothschild & Co to review its entire corporate structure - and confirmed Thredbo isn't off limits, even as it books a stronger year of earnings. The resort's own valuation has nearly halved after a brutal 2026 season, and speculation is already running toward Vail Resorts, Alterra, or a New Zealand operator picking it up. Here's what EVT actually said, and who could buy it.

Ski-E-O! Is the Ski Resort Tycoon Game We Didn't Know We Needed
I'm not a gamer. I'm a skier and snowboarder who happens to have a laptop. So when a ski resort management game called Ski-E-O! landed on Steam, I wasn't expecting to lose an afternoon to it - but here we are. Real mountain terrain, a full weather system, storms that roll in and wreck your snow base, avalanche danger, and enough depth to make RollerCoaster Tycoon feel simple by comparison. Early access lands in November. Here's what a few hours in the free demo actually looks like.

Sugar Bowl, California, Rebuilds Its Historic Village Gondola
The rumours are true: Sugar Bowl is tearing out its Emerald gondola, in place since 1983, and replacing it with a new 8-person Doppelmayr system - nearly doubling uphill capacity to 1,800 people an hour. It's the fourth generation of a gondola line that dates back to 1953, when Sugar Bowl became the first resort on the West Coast to run one at all, and it's just one piece of a $100 million overhaul touching lodges, parking and snowmaking. Here's what's changing, and what's staying the same.

Two Confirmed Dead as Search Continues After Swiss Alps Fire
The death toll from Thursday night's fire at Restaurant Beverin in Thusis, Switzerland, has begun to firm up. One Swiss outlet, citing Graubünden Cantonal Police, reports that two of the five people initially reported missing have now been confirmed dead, leaving three unaccounted for. The building's collapsed stairwell and structural instability have slowed recovery efforts throughout. Here's what's changed since the fire broke out, and what's still unconfirmed.

Selwyn Snow Resort Closes Early as Rain Ends Its 2026 Season
Selwyn Snow Resort has called an early end to its 2026 season, a day after Victoria's Mount Baw Baw did the same. Rain on Thursday stripped what was left of the snowpack, and the cold nights needed to rebuild it through snowmaking never arrived. It's a rough result for a resort that only just found its footing again after being burned to the ground in the 2019-20 Black Summer bushfires and a multi-year rebuild. Here's how the season fell apart, and where Selwyn's been since the fire.

Mt Baw Baw is calling time on its 2026 season this Sunday at 5pm, becoming the first Australian resort to close for the year after warm spells and rain wore through its snowpack. Lifts stop, but the resort stays open, entry fees get waived, and there's one last Bollywood Weekend before the lights go out. Fifty-seven days after opening, here's how the season ended and what it means for the rest of Australia's struggling snowpack.

Arosa to Replace 40-Year-Old Hörnli Lifts With New Gondola and Chair
Arosa's Hörnli sector is getting its biggest overhaul in decades. The 1986 gondola and 1994 chairlift linking toward Lenzerheide are both being replaced, with capacity up, tower count down and a new base station lower on the hill. At roughly CHF 67 million, it is the largest single investment Arosa Bergbahnen has ever made - and the target opening has already slipped a year, to December 2028. Here is what is changing, and why the timeline moved.

Sundance Mountain Resort Is Getting a New High-Speed Quad and More Back Mountain Terrain This Winter
Sundance Mountain Resort's back mountain is finally getting a proper lift. The Electric Horseman Express opens for 2026-27, unlocking a new bowl next to Bishop's Bowl and three expert gladed chutes across roughly 105 fresh acres - on top of the Storyteller ridge run that debuted in preview form last season. It's Sundance's biggest expansion since 1985, and it turns a three-lift slog into a single six-minute ride to Bearclaw Summit.
