Glacier National Park is one of the best places in the United States for a classic mountain road trip: dramatic peaks, turquoise lakes, and trailheads that start right off the road. The park is also huge, lodging inside the park is limited, and summer availability fills up quickly, so having your own Campervan makes planning easier and gives you more freedom day-to-day.
This page covers the planning details Campervan travellers actually need for Glacier, including pick-up locations, the most Campervan-friendly routes, key things to do and hikes, the best time to visit by season, campsite options inside and outside the park, dump stations, and the restrictions that could affect your itinerary.
Going to the Sun Road is Glacier’s signature drive, but it isn’t accessible to many standard campervans and motorhomes.
Vehicle size limits:
- Maximum length: 6.40 metres (21 ft) (including bumpers)
- Maximum width: 2.44 metres (8 ft) (including mirrors)
- Vehicles longer than 6.40 metres or wider than 2.44 metres are prohibited between Avalanche Creek and Rising Sun
- Vehicles over 3.05 metres (10 ft) in height may have difficulty driving west from Logan Pass to the Loop because of rock overhangs
What this means in practice: if your campervan is larger than these limits, plan to park on either side of the corridor and use the free shuttle service to reach Logan Pass, major viewpoints, and popular trailheads.
Going to the Sun Road scenic highlights (plan around Campervan limits)
Lake McDonald Valley base route
Many Glacier focus route
Two Medicine valley route
Visitor centres and ranger programmes are worth popping into if you want context on geyser timings, staying safe around wildlife and current road conditions.
Spring (April to May)
Weather: variable, higher elevation areas still wintry
Pros: Fewer crowds, early-season scenery on the lower elevation sections
Cons: The alpine portion of Going to the Sun Road is usually not open yet, and there is no fixed opening date
Best for: Quieter trips focused on Lake McDonald and lower elevation hikes
Summer (June to August)
Weather: Best overall access, but it’s still cooler at elevation
Pros: The best chance of full park access; the road is usually fully open by early July
Cons: Crowds, parking congestion at Logan Pass, and restrictions can limit Campervan routing
Best for: First-time visitors who want iconic highlights, with an early start strategy
Fall (September to mid-October)
Weather: Crisp mornings, shorter days
Pros: Fewer crowds, strong hiking conditions
Cons: Parts of the road can close due to weather; it's usually fully open until the third Monday in October, but conditions can change quickly
Best for: Hiking-focused trips with flexible day plans
Winter (late October to March)
Weather: Severe winter conditions at elevation
Pros: Quiet, dramatic landscapes
Cons: Limited road access; not a Campervan-friendly season for most visitors
Best for: Not recommended for standard Campervan itineraries
Campsites inside the park
These are the high-value, campervan-relevant front-country campsites to cover in detail. The park’s campsite information includes pitch counts and maximum campervan or trailer lengths — check these against your vehicle before you book.
Campsites and campervan parks outside the park
Gateway towns can be a practical backup when in-park pitches are full, or when you want hook-ups. Focus on West Glacier and the St. Mary or Browning area as the most natural bases, depending on which side you want to start each day.
Waste disposal points
Waste disposal points are not optional planning at Glacier because services are spread out and many campsites have no services.
Only if your Campervan fits the size limits. Vehicles longer than 21 feet (6.4 metres) or wider than 8 feet (2.44 metres) aren't allowed between Avalanche Creek and Rising Sun.
Plan to park up and use the free shuttle service to get to Logan Pass and the main stops. Shuttles operate in summer, are free, and are intended to ease parking congestion.
Policies can change from year to year. In 2026, a timed-entry vehicle reservation was required for specific areas during set hours and dates, in addition to your entry pass; reservations were handled through Recreation.gov. Make sure you check the current rules for the year you're travelling before you arrive.
In 2025, timed-entry reservations were required for west-side access to Going to the Sun Road beyond the Apgar checkpoint and for the North Fork during the published summer dates and times.
There's no set date. The park says it's usually fully open by early July, but the opening depends on snowfall and snow clearance.
Apgar, Fish Creek, St. Mary, Many Glacier, and Two Medicine are the most commonly used developed sites for Campervan travellers. Check maximum length restrictions and your exact pitch type before booking.
Most in-park campsites have no services. Plan on organising water and waste-disposal rather than expecting full mains hook-ups.
Plan around seasonal waste disposal points at managed campsites, and keep a gateway town Campervan site as a backup for a paid disposal point if needed.
Two to three days will do for a highlights trip if you plan your driving carefully. Four to five days is better if you'd like to add Many Glacier hikes, Two Medicine and some quieter time away from the main corridor.
Avalanche Lake is a great first choice on the west side, Hidden Lake Overlook is the classic Logan Pass walk, and St. Mary Falls is a highly rewarding waterfall walk on the east side.
