Deep dive · PickRV editorial
Everything you need to plan Glacier Going-to-the-Sun Road
Going-to-the-Sun Road is the reason an RV trip to Glacier National Park is worth planning around: 50 miles of cliff-hugging alpine highway over Logan Pass that only fully opens once snowplow crews clear nearly 40 avalanche paths. For 2026 the park expects full road opening around July 1 (snowpack-dependent), with the high country accessible into mid-October before fall storms close the pass. Two pieces of news change the 2026 plan. First, Glacier has DROPPED the timed-entry vehicle reservation system parkwide for 2026 - you only need a valid park entry pass, no separate vehicle reservation. Second, a ticketed Logan Pass shuttle program replaces part of the old free system, running roughly July 1 through September 7, and private-vehicle parking at Logan Pass is capped at three hours. The catch for RVers is hard and physical: vehicles and combinations over 21 feet long or 8 feet wide are prohibited on the road's middle section between Avalanche Creek and Sun Point. A 35-foot Class A simply cannot drive the alpine portion. The winning move is to base a right-sized rig at a hookup park near the West or St. Mary entrance, drive the lower road as far as the length limit allows, and ride the shuttle over the pass. In-park campgrounds (Apgar, Fish Creek, St. Mary) are RV-accessible but dry with no hookups. Bears are active all season - store food properly.
Best RV parks
West Glacier KOA Resort
fullKOA · 5 min (2.5 mi) to West Entrance via US-2
Full hookups with 30/50-amp and big-rig pull-thrus, ~2.5 mi from the West Glacier entrance. Best base for a too-big rig: park here, shuttle the pass.
Glacier Peaks RV Park
fullGlacier Peaks (private) · 30 min (14 mi) to West Entrance via US-2
Full water/sewer + 30/50-amp in Columbia Falls. Cheaper west-side base with grocery and laundry in town for longer stays.
St. Mary / East Glacier KOA Holiday
fullKOA · 5 min to St. Mary Entrance via US-89
Full-hookup east-side base, about 5 minutes from the St. Mary gate. Open ~May 21 to Sept 30 - confirm dates for shoulder-season trips.
Apgar Campground (in-park)
dryNPS / Recreation.gov · Inside park near West Entrance, 0 min to Sun Rd west end
In-park, RV sites up to ~40 ft, reservable on Recreation.gov. No hookups - potable water + dump station only. Book 6 months out.
St. Mary Campground (in-park)
dryNPS / Recreation.gov · Inside park at east end of Sun Rd, 0 min to St. Mary
In-park east-side base, sites up to ~40 ft, reservation required. Dry camping with dump station - run a self-contained, solar-friendly rig.
Per-vehicle-type recommendations
rv
Right-size the rig: a Class C 22-26 ft or smaller fits Apgar/St. Mary in-park sites (up to ~40 ft) and the West Glacier KOA. Critically, anything over 21 ft long or 8 ft wide is banned on Going-to-the-Sun Road between Avalanche Creek and Sun Point - a 35 ft Class A cannot drive the alpine middle. Base it at a hookup park and ride the Logan Pass shuttle over the top.
trucks vans
A Class B campervan or truck camper under 21 ft is the ideal Glacier vehicle: it legally drives the entire Going-to-the-Sun Road including Logan Pass, parks within the three-hour cap, and fits any in-park dry site or KOA pull-thru. Pack extra water and a portable power station - in-park campgrounds have no hookups, and east-side cell coverage is thin.
Safety + legal — sourced
NPS Glacier
Vehicles and combinations over 21 ft long or 8 ft wide are prohibited on Going-to-the-Sun Road between Avalanche Creek and Sun Point. Measure your rig before you go - there is no exception, and turning a big rig around on the narrow alpine road is dangerous.
NPS Glacier
Vehicle reservations are NOT required anywhere in the park for 2026, but you still need a valid park entry pass. From July 1, parking at Logan Pass is limited to three hours, weather permitting - plan a shuttle or early arrival for long hikes.
NPS Glacier (Logan Pass shuttle 2026)
The 2026 Logan Pass shuttle is a ticketed program ($1 processing fee per ticket on Recreation.gov, one per person per day), running roughly July 1 through Sept 7. Tickets release 60 days ahead starting May 2 and next-day tickets at 7 p.m. - reserve before you arrive.
NPS Glacier (Bear Safety)
Grizzly and black bears are active all season. Store all food, coolers, and scented items in a hard-sided vehicle or food locker, never at your campsite, and carry bear spray on every trail. In-park dry campgrounds enforce strict food-storage rules.
NWS Missoula / NPS
High-country weather swings fast: snow is possible at Logan Pass even in summer, and the road can close on short notice. Carry layers, check road status the morning of your drive, and never park or stop in marked avalanche/rockfall zones.
Transit from RV base to event
Logan Pass shuttle (ticketed program)
West-side express from Apgar Transit Center / Lake McDonald Lodge and east-side express from St. Mary Visitor Center / Rising Sun, both serving Logan Pass.
Amtrak Empire Builder
Daily Amtrak service to West Glacier (Belton) and East Glacier Park stations; pair with a gateway-park base and the in-park shuttle.
Drive lower Sun Road
Drive your right-sized rig the lower road from the West or St. Mary entrance up to the 21 ft length limit, then transfer to the shuttle for the alpine middle.
