History of Going-to-the-Sun Road

Going-to-the-Sun Road is the first and only road built in Glacier National Park. Officially opened in 1933, the road took over twenty years to build and remains one of the most impressive feats of civil engineering in the United States. Carving through the mountains nearly a century ago, GNP workers used basic hand tools to chip away, drill, and blast their way through the rugged terrain.

Named after Going-to-the-Sun Mountain, the road crosses the Continental Divide at Logan Pass, the highest point on the road at 6,646 feet. Nearly all of the road's route runs through a National Historic Landmark district, and driving it ranks among the most iconic experiences in all of North America.

The road is part of the reason why Glacier is often called the "Crown of the Continent" — not just for its geography, but for the way this road opens that landscape to visitors in such an intimate way.

Going-to-the-Sun Road Map & Route Overview

Going-to-the-Sun Road runs east to west (or west to east, depending on your starting point), connecting the west entrance near West Glacier with the east side near St. Mary. The full route is 50 miles long and typically takes 2–3 hours to drive without stops — though most visitors plan for a full day.

Key landmarks along the route (west to east):

• West Glacier Entrance — Gateway to the park from US-2
• Apgar Village — Visitor center, boat rentals, and the south shore of Lake McDonald
• Lake McDonald — The largest lake in the park, famous for its colorful rocks
• The Loop — A famous hairpin turn with pull-off views and trailhead access
• Bird Woman Falls Overlook — Views of the 492-foot waterfall across the valley
• Weeping Wall — A natural spring seeping through the rock face (can soak your car in spring)
• Logan Pass — The summit, Continental Divide, and visitor center
• Jackson Glacier Overlook — One of the few glaciers visible from the road
• St. Mary Lake — The second largest lake in the park, often mirror-flat at dawn
• St. Mary Entrance — East side gateway near the town of St. Mary

When Does Going-to-the-Sun Road Open?

Going-to-the-Sun Road does not open all at once. The lower sections — near West Glacier and St. Mary — open earlier in spring, while the high alpine section around Logan Pass typically opens in late June or early July depending on snowpack.

Typical opening timeline:

• West Glacier to Avalanche Creek: Opens in mid-April (weather permitting)
• St. Mary to Rising Sun: Opens in mid-April (weather permitting)
• Full road (Logan Pass section): Typically opens late June to early July

The road typically closes for the season in October or November, again depending on snowfall. Always check NPS road conditions before your visit for real-time status.

Best Time to Drive Going-to-the-Sun Road

The most popular time to visit is July through mid-August, when the road is fully open, wildflowers are blooming at Logan Pass, and wildlife activity is high. However, this is also the busiest period.

For a quieter experience, consider:

• Late June — Road just opened, snowfields still present, fewer crowds
• September — Larch trees turn golden, crowds drop significantly, wildlife very active
• Early morning drives — Beat the crowds to Logan Pass regardless of month

2026 Access: No Vehicle Reservations Required

Starting in 2026, the National Park Service has eliminated the vehicle reservation system for Going-to-the-Sun Road. You no longer need to book a timed-entry permit in advance to drive the road.

However, there are still important access rules to know:

• Logan Pass parking limit: Starting July 1, 2026, vehicles may park at Logan Pass for a maximum of 3 hours. Plan your hike and visit accordingly.
• Vehicle size restrictions: Vehicles and combinations over 21 feet long or 8 feet wide are prohibited on the road between Avalanche Creek and the Sun Point parking area. This affects larger RVs and trailers.
• Free shuttle system: The park operates a free hop-on/hop-off shuttle between Apgar and St. Mary, running roughly late June through Labor Day. This is the easiest way to avoid parking stress entirely.

Top Things to Do on Going-to-the-Sun Road

Guided Tours Along the Road

The single best way to experience Going-to-the-Sun Road — especially for first-timers — is with a local guide. Our Going-to-the-Sun Road Guided Day Tour handles all the logistics so you can focus on the views. Your guide will:

Hiking from the Road

Going-to-the-Sun Road provides trailhead access to some of Glacier's best hikes. You don't need to venture deep into the backcountry to find world-class trails — many start right off the road:

• Hidden Lake Overlook (from Logan Pass) — 2.7 miles round trip, moderate, stunning alpine lake views
• Highline Trail (from Logan Pass) — 11.8 miles one way (or as far as you like), legendary ridge walk

Pull off safely and use binoculars when possible. Never approach wildlife — maintain at least 100 yards from bears and 25 yards from all other animals.

Photography Stops

The road has no shortage of iconic photo opportunities. The best dedicated pull-offs for photography include:

Logan Pass Parking Tips (2026)

Parking at Logan Pass is extremely limited (roughly 175 spaces) and fills by 7–8am on peak summer days. With the new 3-hour parking limit starting July 1, 2026, turnover will be somewhat faster — but demand still greatly exceeds supply.

Your best options:

• Arrive before 7am — The only reliable way to guarantee a spot during peak season
• Take the free park shuttle — Runs from Apgar and other stops to Logan Pass; no parking needed
• Book a guided tour — Your guide handles all parking logistics
• Visit in September — Wait times drop dramatically after Labor Day

Driving Tips for Going-to-the-Sun Road

Going-to-the-Sun Road is one of the most beautiful drives in the world — and one of the most challenging. Here's what to know before you go.

Vehicle Restrictions

The road is narrow, with sheer drop-offs and no guardrails in many sections. Vehicle restrictions apply between Avalanche Creek and the Sun Point parking area:

• Maximum length: 21 feet (vehicle + trailer combined)
• Maximum width: 8 feet (including mirrors)
• This means: no large RVs, no trailers over the limit

If you have a large vehicle, you can still access both ends of the road (West Glacier to Avalanche, and St. Mary to Sun Point) and ride the shuttle for the middle section.

Road Etiquette

• Pull-offs are narrow and popular — be patient waiting for a spot
• Yield to uphill traffic in one-lane sections
• Keep moving if there's no safe place to stop — you can always circle back
• Do not stop in the middle of the road for wildlife, even briefly
• Headlights on at all times in the tunnels and overhangs

What to Bring

• Layers — Temperature at Logan Pass can be 20–30°F colder than the valley; bring a jacket even in summer
• Water and snacks — No food services on the road itself; stock up before entering
• Sunscreen and sunglasses — High elevation means intense UV exposure
• Binoculars — Essential for wildlife and glacier viewing
• Bear spray — Required if hiking; available for rent/purchase at most outfitters in Whitefish and West Glacier
• Cash or card for entrance fee — $35/vehicle (or America the Beautiful Pass)

The Free Glacier Park Shuttle System

The free Going-to-the-Sun Road shuttle is one of the best ways to experience the road — especially if you want to hike one-way or skip the parking headache entirely. The shuttle system runs approximately from late June through Labor Day, operating daily from early morning to evening.

Key shuttle stops include:

• Apgar Transit Center (West Glacier side)
• Lake McDonald Lodge
• Avalanche Creek
• The Loop
• Logan Pass Visitor Center
• Jackson Glacier Overlook
• Rising Sun (St. Mary side)

You can hop on and off at any stop. The shuttle is free with park admission and is ADA accessible. During peak season, shuttles run every 15–30 minutes on the most popular segments.

Pro tip: Take the shuttle up to Logan Pass, hike the Highline Trail partway, and catch a shuttle back down. This is one of the best ways to experience the park with minimal stress.

Where to Stay Near Going-to-the-Sun Road

Lodging options range from rustic park lodges to full-service hotels just outside the park boundary.
