The Overview

Mammoth Mountain spans 3,500 acres across California's Eastern Sierra with a summit at 3,369 metres and a base at 2,424 metres, delivering 945 metres of vertical drop. The resort operates 180 named runs distributed across 15% beginner, 48% intermediate, 24% advanced and 13% expert terrain. Annual snowfall averages 10.16 metres at the base, rising above 400 inches at upper elevations where the summit reaches 11,053 feet. The 2022-23 season recorded over 700 inches at Main Lodge, marking the snowiest winter on record.
The mountain's 65% north-facing aspect ensures reliable snow preservation from November into June, with terrain spreading horizontally across four distinct base areas. Chair 23 accesses steep chutes and exposed upper bowls above treeline, whilst Chair 22 serves wind-sheltered expert runs including the Avalanche Chutes on Lincoln Mountain. The Panorama Gondola reaches the summit in seven minutes, connecting to Cornice Bowl and advanced alpine terrain. Unbound Main Park anchors a terrain park system comprising 10 parks, two halfpipes, over 100 jibs and 50 jumps across 100 acres.
Main Lodge sits at 2,743 metres and serves as the historic hub, whilst Canyon Lodge and Eagle Lodge provide family-oriented beginner zones with dedicated learning areas. The Village at Mammoth connects to Canyon Lodge via a 15-passenger gondola, creating pedestrian access between lodging and slopes. Weekends draw crowds from Los Angeles and Southern California, though the resort's sprawling layout disperses skiers efficiently. Wind frequently closes upper lifts during storms, sending advanced riders to the protected Chair 22 zone.
Mammoth is included on both the Ikon Pass with unlimited access and the Mountain Collective with two days. The 2025-26 season opened 14 November and runs through 25 May, with extensions possible into June or July during heavy snow years. The resort attracts Olympic athletes training in its world-class terrain parks and suits intermediates seeking long groomed runs, experts chasing steep lines, and families requiring varied terrain. Altitude, massive acreage and exceptional park infrastructure define the Mammoth experience.

When to visit Mammoth Mountain
The 2025-26 season opened 20 November following snowmaking preparation and runs through 25 May 2026, with daily lift operations from 7:30am to 2:00pm during spring hours beginning in May. Mammoth typically operates from early November into June, with exceptional years extending into July or August. The 1994-95 season opened 8 October and closed 13 August, whilst 2017 closed 6 August and 2022-23 ran until 6 August following record snowfall. Season length averages over 200 days.
Annual snowfall averages 400 inches at base elevations, exceeding 10 metres total accumulation and rising past 500 inches at the 11,053-foot summit. The 2022-23 winter delivered over 700 inches at Main Lodge and nearly 900 inches at the summit. February and March historically produce the heaviest snowfall, with the first week of March averaging 43 centimetres. November typically receives 32 inches, whilst December through February each deliver 67 to 71 inches. Snowmaking covers 33% of terrain, establishing a reliable early-season base.
January and February offer peak powder conditions, whilst March balances fresh snow with increasing sunshine. April and May deliver spring corn snow under bluebird skies, with temperatures rising but coverage holding at altitude. The resort benefits from 300 days of annual sunshine. The 2025-26 season received 87 inches in February alone, securing a Memorial Day closing despite a slower early winter. Mammoth's east-side Sierra location captures Pacific storms whilst the 2,424-metre base elevation prevents rain.
Night of Lights returns 14 December annually at Canyon Lodge with fireworks and family activities. Elevation Mammoth gay ski week runs 12-16 March 2025. Ikon Pass holders receive Early Ups exclusive morning access on select dates with complimentary breakfast at McCoy Station.

Getting there
Getting to Mammoth Mountain, and where to stay
Mammoth Mountain rises from the eastern slope of California's Sierra Nevada range in Mono County, 58 kilometres southwest of the Nevada state line. The resort sits above the town of Mammoth Lakes at 2,424 metres base elevation, surrounded by the Inyo National Forest and Long Valley Caldera volcanic landscape. The summit reaches 11,053 feet, making Mammoth California's highest lift-served ski area. Volcanic geology defines the terrain, with the mountain itself a lava dome complex.
Mammoth Lakes town lies 6.4 kilometres from Main Lodge along Highway 203, offering lodging, dining and services for a resort community. The Village at Mammoth provides slopeside accommodation, restaurants and pedestrian access via gondola to Canyon Lodge. Los Angeles sits 307 miles south via US 395, Reno 168 miles north, and San Francisco 360 miles west during winter when Tioga Pass through Yosemite closes seasonally. Highway 395 runs north-south through the Eastern Sierra, providing primary access.
The drive from Los Angeles takes five hours via Interstate 14 north to Highway 395, passing through the Owens Valley with views of the White Mountains and Ancient Bristlecone Pine Forest. From Reno the journey requires three hours south on US 395, passing Mono Lake and the ghost town of Bodie State Historic Park. San Francisco requires six to seven hours in winter via Highway 99 or Interstate 5 east, then Highway 395 south, as Tioga Pass closes from approximately October through May.
Mammoth Yosemite Airport sits 10 minutes east on Highway 395 with seasonal United Airlines service from Los Angeles, San Francisco and Denver, plus Advanced Air from Carlsbad and Hawthorne. Eastern Sierra Regional Airport in Bishop operates 45 minutes south with year-round United flights from San Francisco and seasonal Denver service beginning December. Mammoth All Weather Shuttle, Mammoth Taxi and rental cars serve both airports. Eastern Sierra Transit Authority operates free shuttles between Reno Airport and Mammoth. Winter driving requires chains during storms.

Stelvio Glacier Suspends Summer Skiing, Leaving Continental Europe Without a Lift-Served Slope
Italy's Stelvio Glacier has pulled the plug on summer skiing from August 15. It was the last lift-served ski option left standing in continental Europe, and now there's none. Operator SIFAS pointed to persistent heat, storms, and a snowpack that simply wasn't refreezing overnight anymore. The cable car keeps running. Whether skiing comes back later this summer depends on the weather turning - and right now, nobody's promising anything.

Maverick Mountain's Only Chairlift Destroyed as Sand Creek Fire Tears Through Montana Ski Area
Firefighters saved every base building at Maverick Mountain, Montana, but the resort's sole chairlift didn't survive the Sand Creek Fire. Owners Erik and Kristi Borge say the lift is "most likely" out for the 2026/27 season after flames tore through the mountain on August 8. The wildfire has since grown past 27,700 acres with zero percent containment. It's a gutting result for the tiny, one-lift operation near Dillon - though the lodge, groomers and equipment all made it through untouched.

Fairmont Niseko: New Luxury Resort Revives Stalled La Plume Site for Early 2028 Opening
Fairmont is bringing its second Japanese property to Niseko, and this one's got history. The 165-room resort will rise on the site of the stalled La Plume project, which collapsed into bankruptcy in 2025 before J-Will Partners bought the site for redevelopment. Set between Mount Yotei and Mount Annupuri, it's slated for an early 2028 opening - putting it in play for the 2027/28 season. Expect two restaurants, a spa, onsen bathing, and a kids' club, a short drive from Niseko Village and Hirafu.

Spain Moves to Ban Smoking at Ski Resorts Under New Tobacco Law
Spain's government has approved a draft tobacco law that would ban smoking across a wide range of outdoor spaces, including sports venues - a category Spanish winter sports media expect to cover ski resorts, potentially extending to slopes and lifts themselves. The rules would also apply to e-cigarettes and vaping devices, even nicotine-free ones. The bill still has to clear the Spanish parliament before any ban, signage, or fines can take effect.

South Tyrol Approves New 16-Person Ciampinoi Gondola in Val Gardena
South Tyrol has approved a full rebuild of the Ciampinoi cable car in Selva di Val Gardena, replacing the current 12-person gondola with a 16-person cabin and a new mountain-station restaurant. Capacity is capped at 3,200 people an hour rather than the 3,600 the operator wanted, and 250,000 euros must go toward compensatory measures. No construction or opening date has been set, though the upgrade is partly aimed at clearing bottlenecks before the 2031 Alpine Ski World Championships.

La Thuile's New Cable Car Replaces Two Ageing Chairlifts
La Thuile is spending 38.7 million US dollars on a new 10-person cable car linking Les Suches to Chaz Dura, replacing the La Combe and Chaz Dura chairlifts after nearly forty years of service. Built by Leitner, the new cable car runs 1,950 metres to a top station at 2,576 metres, carrying up to 3,000 people an hour with a six-minute ride. It also improves the connection to La Rosiere in France via the Petit-Saint-Bernard Pass, and is on track to open for the 2026/27 season.

The Remarkables Adds Scarpa Bowl to Its Inbounds Terrain
The Remarkables is adding new inbounds terrain for winter, bringing the Scarpa Bowl - known locally as the Toilet Bowl - into its lift-accessed network after years as backcountry-only ground. The roughly 500 metre run is reached by bootpacking from the top of the Sugar Bowl chairlift, with a shuttle picking skiers up from the road at the bottom. It's a smaller, faster addition than the resort's planned Doolans expansion, though the new terrain hasn't opened yet due to a lack of snow this season.
