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. The resort does not offer night skiing but extends spring hours to maximise morning corn snow. Chair 1 banner breakthrough and opening day ceremonies feature Woolly the mascot and complimentary beverages.

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.

FIS Weighs Holding World Championships in Almost Every Winter, Starting 2032
The International Ski and Snowboard Federation is looking at a major shake-up to its title events calendar. From 2032, World Championships could run not just in odd-numbered years but in every non-Olympic winter too, effectively putting a global title event on the calendar almost every season. The FIS Council has approved the concept following a feasibility study, though an accelerated rollout as early as 2028 is also under consideration.

Mount Buller Becomes Latest Australian Resort to Call Time Early on 2026
Mount Buller closes out its 2026 season this Sunday, joining Falls Creek, Hotham and Charlotte Pass in a cluster of closures landing almost simultaneously and roughly a month ahead of schedule. The culprit is stark: Spencers Creek's benchmark snow depth hit 31.2cm on 3 September, just 18% of the 73-year average and an all-time low for this point in the season. Six of Victoria and NSW's best-known resorts will have shut their lifts early within a span of about two and a half weeks.

Tremblant to Add New Timber Summit Ski Sector for 2027/28 Season
Tremblant has confirmed a major expansion of its Quebec ski area, with a new Timber Summit sector adding 62 acres of terrain, eight trails and a high-speed quad chairlift for winter 2027/28. It's part of a CAD 42.5 million investment that also includes a new beginner learning zone at Versant Soleil opening this coming season. The project has grown considerably since it was first announced back in 2020, when it carried a far smaller budget and an opening date that never eventuated.

Mount Hotham to Close for the 2026 Season on Sunday, September 6
We knew when the Bird Bath Pond Skim showed up on Hotham's Instagram that the season was on its way out. It's been a rough one - I only managed two days on snow all year, at Falls Creek - and now Baw Baw, Selwyn and Hotham have all called it, possibly the worst Australian season I've seen in a decade. Hotham's last day of lift operations is Sunday, 6 September, with a Retro Day, Father's Day après and closing sales before the lifts stop turning for good.

Thredbo to Replace Ageing Gunbarrel Quad With New Six-Seat Chairlift for 2028
Thredbo Alpine Resort has confirmed plans to replace its 37-year-old Gunbarrel quad chairlift with a new six-seat Doppelmayr D-Line, targeting winter 2028. The AUD 35 million project will keep travel time roughly the same but lift capacity from 2,800 to 3,000 skiers per hour. It's part of a broader investment push that also includes doubled snowmaking capacity at Friday Flat for 2027, with the ageing Kosciuszko Express now flagged as the resort's next major lift replacement after Gunbarrel.

Why Glaciers Are Collapsing - And What Happens When They Do
A deadly flood on the Nepal-China border, a decade-old tragedy on Italy's Marmolada, and an unstable glacier right now above a village near Zermatt - three very different mountain ranges, the same underlying story. Warming ice is destabilising terrain that was considered settled for generations, and the results range from catastrophic floods to slow-motion monitoring situations that could go either way.

Pitztal Glacier Set to Reopen for the 2026/27 Ski Season on 26 September
Tyrol's highest ski area is gearing up to open a full month ahead of most of the Alps. The Pitztal Glacier is scheduled to start its 2026/27 season on Saturday 26 September, running through to 2 May 2027, with the lower-altitude Rifflsee area following in December. High-altitude terrain up to 3,440 metres gives the glacier a head start on snow, though as always, the actual opening extent will depend on how September's weather plays out. Early online ski pass bookings can save up to 30%.

Understanding the Mammoth Mountain snow report
Get the latest Mammoth Mountain snow report — real-time snowfall, snow depth, and mountain weather for this California resort, spanning 2424m to 3369m in elevation.
Snow measurements
Base depth, summit depth, and recent snowfall are the core numbers to watch. At Mammoth Mountain, summit conditions (3369m) can differ noticeably from the base, so we break both out separately rather than showing a single average.
Weather conditions
Current weather conditions affect snow quality. Cold temperatures with low wind typically preserve snow quality, while warm temperatures or rain can impact conditions negatively — something worth watching closely at Mammoth Mountain's 2424m base elevation, where temperatures run milder than the summit.
Data sources
Mammoth Mountain snow data is collected through a combination of on-mountain reports and weather forecasting services, giving you both official resort updates and independent forecast data in one place. The mountain is served by 31 lifts, including 9 quad chairlifts and 4 6-person chairlifts.
When to check
Snow reports are typically updated early morning and late afternoon. For the most current conditions, check back regularly, especially if a winter storm is approaching.
