I-70 traffic continues onto US-6
Keystone-bound drivers generally leave I-70 near Dillon and follow US-6. Tunnel-area congestion may ease before the exit while US-6 remains slow or snowy. COtrip covers both segments, so check the full route and the return rather than treating the interstate exit as arrival.
River Run and Mountain House are distinct bases
River Run centers on River Run Gondola and Summit Express access. Mountain House serves Peru Express and nearby learning terrain. Lesson check-in, rentals, and lodging should determine the portal; carrying children's gear between the two is a poor opening strategy.
Parking information is date-sensitive
Keystone's lot names, prices, shuttle arrangements, and premium areas can change. Use the resort's current parking map and roadside signs. Do not assume that a historically free or open lot has the same status this season, and keep the parked-lot name in every group member's phone.
Dercum Mountain holds the first wave
Many skiers upload to Dercum Mountain before moving toward North Peak and The Outback. That makes the initial gondola and Summit Express decision more important than later acreage. If upper connections are delayed, ski open Dercum terrain rather than waiting at a closed route toward another mountain.
Night skiing is not a universal fallback
Night skiing has operated on selected dates and terrain, often from the River Run side, but schedules can narrow during the season. Verify the operating calendar, included access, and last lifts. A crowd forecast cannot tell you whether tonight's session exists.
A split day needs storage and meal planning
Leaving after morning laps and returning for night operations can avoid continuous fatigue, but only if equipment storage, parking re-entry, and meals are settled. Families should also account for temperature drops after sunset. Treat the evening as a second session, not free extra hours attached to every day ticket.
