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 big, accommodation inside the park is limited, and summer availability disappears quickly, so having your own Campervan makes planning simpler and gives you more freedom day-to-day.
This page covers the practical 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, waste disposal points (dump stations), and the restrictions that can affect your itinerary.
Going to the Sun Road is Glacier’s signature drive, but it’s not accessible to many standard Campervans and motorhomes.
Vehicle size limits:
- Maximum length: 21 feet (including bumpers) — 6.4 metres
- Maximum width: 8 feet (including mirrors) — 2.4 metres
- Vehicles longer than 21 feet or wider than 8 feet are prohibited between Avalanche Creek and Rising Sun
- Vehicles over 10 feet 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 to reach Logan Pass, major viewpoints and popular trailheads.

Visitor centres and ranger programmes are worth checking out if you want context on geyser timing, wildlife safety and current road conditions.
Spring (April to May)
Weather: variable, higher-altitude areas still wintry
Pros: Fewer crowds, early-season scenery on the lower-altitude sections
Cons: The alpine section of Going to the Sun Road is typically not open yet, and there's no fixed opening date
Best for: Quieter trips focused on Lake McDonald and lower-altitude hikes
Summer (June to August)
Weather: Best overall access, but still cooler at altitude
Pros: The best chance for 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 wanting iconic highlights, best 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 typically 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 altitude
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 the number of pitches and the maximum campervan or trailer lengths, which you should check against your vehicle before booking.
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 aren't optional when planning at Glacier because services are spread out and many campsites have no hook-ups.
Only if your Campervan meets the size limits. Vehicles longer than 6.4 metres or wider than 2.4 metres are not allowed between Avalanche Creek and Rising Sun.
Plan to park up and use the free shuttle to get to Logan Pass and the main stops. Shuttles run in summer, are free and are meant to ease parking congestion.
Policies can change from year to year. In 2026, a timed-entry vehicle reservation was needed for certain areas during set dates and times, in addition to your entry pass, and reservations were handled via Recreation.gov. Always check the current rules for your year of travel before you arrive.
In 2025, timed-entry reservations applied to the west-side access to Going to the Sun Road beyond the Apgar checkpoint and to the North Fork during the posted summer dates and opening hours.
There isn’t a fixed date. The park says it’s usually fully open by early July, but the opening depends on snowfall and snow‑clearing conditions.
Apgar, Fish Creek, St. Mary, Many Glacier and Two Medicine are the most commonly used developed campsites for campervan travellers. Check maximum length limits and your exact site type before booking.
Most campsites in the park are dry — plan to sort water top-ups and waste disposal (service points) rather than rely on full hook-ups.
Plan around seasonal waste-emptying points at established campsites, and keep a gateway town Campervan park as a backup if you need to pay to empty your tanks.
Two to three days will do for a highlights trip if you plan your driving carefully. Four to five days is better if you want to add Many Glacier hikes, Two Medicine and a bit of quieter time away from the main corridor.
Avalanche Lake is a strong first choice from the west side, Hidden Lake Overlook is the classic Logan Pass walk, and St. Mary Falls is a very rewarding waterfall walk on the east side.
