A Field Guide

What Keystone actually feels like.

A three-mountain Summit County resort on the Snake River — Dercum Mountain, North Peak, and the Outback span 3,149 acres at the foot of the Continental Divide, the River Run gondola climbs from the village to the Summit House at 11,640 feet, and Schoolmarm's 3.5-mile top-to-bottom green run is the longest beginner trail in the Colorado Rockies.

Three mountains, one family resort

Activities at Keystone

Three connected ski mountains, night skiing on Dercum until 8 p.m., the world's largest Kidtopia snow fort at the gondola summit, and Lake Dillon a five-minute drive from River Run Village.

Skiing the Three-Mountain Complex
01

Skiing the Three-Mountain Complex

Keystone's three connected mountains — Dercum, North Peak, and the Outback — span 3,149 acres on a single Epic Pass, served by 20 lifts and the River Run gondola. Schoolmarm at 3.5 miles is the longest beginner trail in the Colorado Rockies; the bumps and gladed trees of the Outback hold the locals' steeps; and the Bergman, Erickson, and South Bowls above North Peak open snowcat-accessed terrain on the back side. Snowmaking blankets 600+ acres, opening reliably in mid-October — Keystone is typically the first big-mountain Colorado resort to open each season.

02

Night Skiing on Dercum Mountain

Keystone is the only major Colorado resort that runs full night skiing — 200+ acres on Dercum lit by floodlights, with the River Run gondola, Argentine, Peru, and Ranger lifts running until 8 p.m. on Friday and Saturday. Night skiing is included with every lift ticket and Epic Pass; rental crowds drop 70% from the daytime peak. The single most underrated Keystone perk for parents who want the morning off and the kids back on the snow at sunset.

03

Kidtopia & the World's Largest Snow Fort

At the top of the River Run gondola, Adventure Point hosts the Kidtopia snow fort — 12,000 cubic feet of carved snow tunnels, ice slides, and turret towers, rebuilt every December to claim the Guinness world record. Right next door: a four-lane lift-served tubing hill that runs both day and night, included on every kids' resort plan. Free, ungated, no reservations — the pure Keystone family-ski selling point.

Hot Tub & Apres at River Run Village
04

Hot Tub & Apres at River Run Village

River Run Village wraps around the gondola base with the Snake River cutting through the middle — Inxpot for a 4 p.m. coffee or wine, Kickapoo Tavern for the apres burger, and Pizza on the Plaza for a kid-easy pie. Most of our larger Keystone rentals at Lone Eagle, Timbers, and Hidden River Lodge include private hot tubs; the Snake River footbridge connects the gondola plaza to the Mountain House parking lot in a four-minute walk.

05

Ice Skating on Keystone Lake

Keystone Lake — a 5-acre pond at the base of Lakeside Village — is the largest Zamboni-maintained outdoor skating rink in North America. Open daily 10 a.m. to 9 p.m. through the ski season, $20 with rentals, free for hotel and HOA guests at most properties. Bonfires, marshmallow stations, and a heated rental hut on the perimeter; the second indoor rink at the Keystone Conference Center handles bad-weather days.

06

Lake Dillon & Summer Mountain Biking

Once the snow melts (June onward), Lake Dillon sits five miles north of River Run Village — Dillon Marina runs sailboat charters, paddleboard rentals, and the Tiki Bar at the docks for a sunset hour. Keystone Bike Park converts the River Run gondola to lift-served downhill mountain biking June through September; the Keystone Gulch road climbs to the Continental Divide on the locals' Sunday morning gravel ride.

Keystone is the only major Colorado ski resort that runs night skiing under the lights — Dercum stays open until 8 p.m. on weekends, and the world's largest snow fort sits right at the top of the gondola. It's the family ski week that starts at sunrise and doesn't end at the chairlift's last load.

Before you book

Trip Planning, Answered

Best season, the DEN airport drive over Loveland Pass, altitude acclimation at 9,280 feet, and what a Keystone ski week actually costs.

When is the best time to visit Keystone?
Keystone is the first major Colorado resort to open most years — opening day lands in mid-October, and Dercum is reliably top-to-bottom by Thanksgiving. The deepest snow lands in February and March, with daytime base highs of 25–35°F. Spring-skiing weeks (mid-March through closing in mid-April) trade the cold for sunshine and lower lift-line traffic. Summer (mid-June through August) is the second peak — Lake Dillon's sailing and concert season, the Keystone Bike Park, and daytime highs of 70–75°F. Mid-September through early October is the locals' aspen color window, with off-peak rates 30–40% below holiday weeks.
What's the closest airport to Keystone?
Denver International (DEN) is the standard — 90 miles east, a 90-minute drive on I-70 in dry conditions and 2.5–3 hours during winter weekend storms. Eagle County Regional (EGE) is 80 miles west and a 75-minute drive in good weather; smaller, fewer flights, but storm-week sanity. The Colorado Mountain Express shuttle from DEN drops directly at most rentals; reservations recommended 48 hours ahead during holiday weeks.
How long should I stay in Keystone?
A long weekend (3–4 nights) is enough to ski Dercum and one of North Peak or the Outback, do an evening on Keystone Lake, and adjust to 9,280-foot base altitude. Five to seven nights lets you ski all three mountains, day-trip to Breckenridge or Vail on the Epic Pass, and absorb the elevation. For families with first-time skiers, plan at least four nights — Schoolmarm's 3.5-mile beginner run is best appreciated with two or three repeat laps in the same week.
Do I need a car in Keystone?
Not strictly. The free Summit Stage bus connects Keystone with Frisco, Dillon, Silverthorne, Breckenridge, and Copper Mountain every 30 minutes. The free Keystone shuttle loops the four base villages (River Run, Mountain House, Lakeside, Argentine) every 20 minutes during ski hours. A car is useful for Lake Dillon, Sapphire Point, Keystone Gulch, and the Outlets at Silverthorne. From October through May, snow tires or 4WD/AWD with M+S-rated tires are required on I-70 and US-6 under Colorado's Traction Law — most rental agencies at DEN and EGE include them automatically in winter.
What's the weather like in Keystone?
Keystone spans 9,280 feet at the village to 12,408 feet at the top of the Outback Bowl. Winter (December–March) averages 235 inches of snowfall on the mountain, with daytime base highs of 25–35°F and overnight lows in the single digits or below zero. Summer (June–August) is dry, sunny, and temperate — 70–75°F daytime highs, 40–50°F nights, occasional afternoon thunderstorms above the tree line. Spring and fall swing widely between snow and sun. Pack layers year-round, drink twice as much water as you'd expect at sea level, and budget a day to acclimate.
Is Keystone good for families?
Yes — Keystone is widely considered the easiest big-mountain Colorado resort for families. Schoolmarm's 3.5-mile run is the longest beginner trail in the Rockies; the Kidtopia snow fort and Adventure Point tubing hill at the gondola summit are free with any lift ticket; and Keystone is the only major Colorado resort that runs full night skiing for late-afternoon kid laps. Off the slopes, the Keystone Lake skating rink, the heated Snake River footbridge, the Keystone Stables sleigh rides, and the Frisco Historic Park cover most kid-weather contingencies. Most of our larger Keystone rentals include game rooms, hot tubs, and bunk rooms.
Where should I stay in Keystone?
Four base neighborhoods cover Keystone. River Run Village wraps the gondola plaza — the walk-everywhere, ski-in choice, with restaurants and shops at the door. Mountain House sits west of the Snake River with shorter lift lines for Schoolmarm beginners and the Peru chair. Lakeside Village faces Keystone Lake, the skating-rink-and-hot-tub neighborhood, with the free shuttle one stop from the gondola. Settlers Creek and the Timbers are quieter, more residential, with HOA shuttle service to the lifts. RedAwning's Keystone inventory covers all four neighborhoods.
How much does a Keystone vacation rental cost?
Keystone nightly rates typically run $150–$300 for a one- or two-bedroom condo and $400–$1,500+ for larger group homes or true ski-in/ski-out units at Lone Eagle and the Timbers. Holiday weeks (Christmas, MLK, Presidents' Day, Spring Break) carry the highest pricing — book six to nine months ahead. Off-peak weekdays in late January or April can drop 40–60% below holiday rates. Most rentals require a 1–2 night minimum; major holidays often require a full 5–7 night stay.
Are ski-in/ski-out rentals available in Keystone?
Yes — true ski-in/ski-out runs concentrate at Lone Eagle Condominiums and the Timbers on Dercum's eastern slope, both two minutes from the River Run gondola via heated brick paths. Walk-to-gondola condos cluster at Black Bear Lodge, Hidden River Lodge, and the Springs at River Run Village. Walk-to-Mountain-House properties (under five minutes to the Peru and Argentine lifts) include the Tenderfoot, Cinnamon Ridge, and the Pines. RedAwning's Keystone inventory tags ski-in, walk-to-lift, and shuttle-only properties separately so you can filter on the booking page.
Do I need to worry about altitude sickness in Keystone?
Plan for it. Keystone's 9,280-foot base elevation puts about 30% of first-time visitors into mild symptoms in the first 24 hours — headache, mild nausea, restless sleep, shortness of breath on stairs. Drink twice your normal water (oxygen displacement is the real culprit), skip alcohol the first night, and consider sleeping one night in Denver (5,280 ft) or Frisco (9,097 ft) on the way up. Severe altitude sickness is rare below 10,000 feet, but if symptoms worsen, descend. Local pharmacies in Keystone, Dillon, and Silverthorne stock oxygen canisters for $20–30 if you need a top-up.
