Glacier National Park sits in the northwest corner of Montana against the Canadian border. Glacier Park International in Kalispell is the closest commercial airport at roughly 30 miles from the West Entrance — but choosing the right airport depends on your travel dates, your budget, and which side of the park you plan to explore most.
Three things shifted at Glacier this season that affect how you plan the trip. Vehicle reservations are completely gone in 2026 — no advance pass needed to drive in through any entrance. The Logan Pass shuttle is now reservation-only (book at Recreation.gov; $1 processing fee; tickets release on a rolling 60-day window or at 7 p.m. the night before). And Glacier Park International Airport (FCA) is running phased runway rehabilitation that closes the runway Monday at 6 p.m. through Friday at 10 a.m. for four consecutive weeks in July — roughly 40% of July capacity is gone on weekdays. Midweek July arrivals must use Missoula (MSO) or Great Falls (GTF). Verify the current schedule at iflyglacier.com before finalizing any July itinerary.

These are the questions travelers have when planning a Glacier trip — including the ones that seem simple but have a real catch.
Glacier Park International in Kalispell is the right answer for most travelers outside of July — it’s the closest, and the drive east on Hwy 2 through Columbia Falls to West Glacier is effortless and scenic. The airport is small with one terminal, short security lines, and on-site rental cars. What complicates 2026 planning is the runway rehabilitation: the main runway is closed Monday evenings through Friday mornings for four consecutive weeks in July — roughly 40% of July capacity vanishes on weekdays. For July travel, this detail matters more than which airport is technically closest. FCA is again fully operational from August onward.
The National Park Service eliminated timed-entry vehicle reservations park-wide for the 2026 season — a significant change after five years of the permit system. You can drive in through the West Entrance, St. Mary, Many Glacier, Two Medicine, or the North Fork at whatever time suits your schedule. What replaced vehicle reservations at Logan Pass is a three-hour parking limit starting July 1 — and a new reservation-only shuttle that runs to Logan Pass from both east and west sides of Going-to-the-Sun Road. The shuttle requires a $1 ticket booked at Recreation.gov; tickets release on a rolling 60-day window and at 7 p.m. the night before. Download your ticket before you lose cell service, which happens quickly after entering the park.
Bozeman is Montana’s aviation hub — every major carrier serves it, competition keeps prices down, and Southwest Airlines flies there (no other Montana airport). If a Bozeman fare is substantially cheaper and you’re already planning a road trip that includes Yellowstone, the extra driving often pencils out. Missoula is the sweet spot for price-proximity: it frequently undercuts Kalispell on fares by a meaningful margin, and it’s only 2.5 hours from West Glacier through some of Montana’s most striking countryside. The drive north from Missoula runs along the eastern shore of Flathead Lake — 28 miles long, the largest natural freshwater lake west of the Mississippi — making the extra drive genuinely worthwhile on its own.
FCA punches above its size in summer. Airlines add seasonal routes specifically targeting Glacier visitors — direct flights from Los Angeles, Chicago, Dallas, Phoenix, Portland, San Francisco, Las Vegas, and New York appear in peak season that don’t operate year-round. Year-round reliable connections include Denver, Minneapolis, Salt Lake City, and Seattle. If your city doesn’t connect directly, a single-connection through any of those four hubs generally works well. Important for 2026 planning: check the airline’s specific July schedule at iflyglacier.com — carriers adjust their operating windows around the runway closure, and some routes shift to weekends-only during that period.
Southwest serves Bozeman (BZN) heavily, making it the natural pick for Southwest loyalists. The 4.5-hour drive north from Bozeman to Glacier is manageable for a week-long trip — and if you’re combining Glacier with Yellowstone, Bozeman is the hub that makes both parks accessible in one road trip. The route from Bozeman north through Helena, Great Falls, and into the Flathead Valley gives you a real introduction to Montana’s scale: open plains rolling into the foothills of the Rockies. Southwest’s point-to-point routing also means no connection penalties — if your home city has a direct Southwest flight to Bozeman, the price difference over Kalispell can be substantial enough to make the extra drive worthwhile even for a shorter trip.
Amtrak’s Empire Builder is one of the most scenic train routes in North America, and it stops directly at Glacier’s doorstep. In July 2026, it’s also the most reliable midweek option for reaching the west side of the park — the runway closure at FCA affects flights, not the train. The Whitefish depot is 25 miles from West Glacier, and the historic building is worth a stop in its own right. The West Glacier and East Glacier Park stations put you even closer. The trade-off is the Empire Builder’s chronic delay record — this is a route for travelers who value the journey as part of the trip. From Whitefish, some lodges offer shuttle service; within the park, the reservation-only Logan Pass shuttle covers the most popular hiking trailheads without a car.
This is the question experienced Glacier visitors know to ask. The west side near West Glacier, Apgar, and Lake McDonald has more lodging options, more services, and is the entry point most first-timers use for Going-to-the-Sun Road. The east side — St. Mary, Many Glacier, Two Medicine — has a completely different character. Mountains rise sharply from the open prairies of the Blackfeet Nation, giving views the forested west side can’t match. Many Glacier is frequently described by rangers and returning visitors as the most spectacular valley in the park. If your trip focuses on Many Glacier or Two Medicine, Great Falls (GTF) is genuinely the more practical airport — it’s closer to those entrances than Kalispell is, and fares are often lower.
Peak crowds hit in July and August — the same weeks as FCA’s runway closure, peak airfares, and the highest temperatures on record. September changes the equation: crowds thin noticeably after Labor Day, fall color begins appearing in the high country, elk start bugling in the meadows, huckleberries (Glacier’s iconic wild fruit) reach peak ripeness, and the daily afternoon thunderstorms of summer ease. Going-to-the-Sun Road remains open and the Logan Pass shuttles continue operating through September, weather permitting. Flight fares drop, rental car availability improves, and popular trailhead parking is actually manageable — a complete reversal from July conditions.
Drive times shown are to the West Glacier entrance, the most commonly used entry point. The east side entrances — Many Glacier, St. Mary, Two Medicine — add significant driving time from Kalispell but are meaningfully closer from Great Falls.

Glacier Park International Airport’s main runway was last resurfaced in 2009 and reached the end of its expected 15–20-year lifespan. The airport is running phased rehabilitation throughout July 2026 with the runway closed Monday at 6:00 p.m. through Friday at 10:00 a.m. for four consecutive weeks. Approximately 40% of July flights are affected. Weekend flights — Friday morning through Monday evening — operate normally. For midweek July travel, Missoula (MSO) and Great Falls (GTF) are both solid alternatives at 2.5 hours from their respective sides of the park. Confirm the current flight schedule at iflyglacier.com before booking.
Glacier holds one of the highest grizzly bear densities in the contiguous United States. The National Park Service strongly recommends carrying bear spray on every trail longer than a short nature walk — and knowing how to use it before you need it. Buy or rent bear spray in Whitefish or Kalispell before entering the park; transportation security rules prohibit it on commercial flights. Hike in groups of four or more — a grizzly attack has never been documented on a group of four or more in Glacier’s recorded history. Make noise on trails, especially near streams where water drowns out your footsteps. Never run from a grizzly. The Grinnell Glacier Trail in Many Glacier saw a bear-related incident in May 2026; always check current NPS trail closures at nps.gov/glac before setting out.
There are no gas stations inside Glacier National Park on the west side. The small station at West Glacier Village, just outside the entrance, occasionally runs low during peak summer weekends. Fill completely in Kalispell, Whitefish, or Columbia Falls before heading in. On the east side, St. Mary has limited fuel. If you’re doing a full vehicle crossing from west to east on Hwy 2 through the southern boundary of the park, the 50-mile Going-to-the-Sun Road itself has no services — plan fuel around the towns at each end.
Assume your phone won’t work once you pass through the park entrance — because for much of Glacier, it won’t. Download everything before you arrive: your shuttle ticket, offline maps (Maps.me or Google Maps offline), campground and lodge reservations, trail maps, and the NPS Glacier app. Take screenshots of anything important. Physical maps are available at entrance stations and visitor centers. Apgar Visitor Center and St. Mary Visitor Center have better connectivity than most of the park interior. Going-to-the-Sun Road itself and the backcountry are largely a dead zone. A downloaded shuttle ticket that won’t load is a ticket you can’t use.
Peak crowds and peak prices hit simultaneously in July and August — the same weeks as FCA’s runway disruption. September changes everything: crowds drop sharply after Labor Day, fall color begins appearing at higher elevations, elk are bugling in meadows throughout the park, huckleberries reach peak ripeness, and the afternoon thunderstorms of August ease off. Logan Pass remains accessible and the express shuttles continue running through September, weather permitting. Airfares fall, rental car availability improves, and Logan Pass parking is genuinely manageable — sometimes even available after 8 a.m., which never happens in July. For travelers with any schedule flexibility, September deserves serious consideration.
- Step 1: If your trip includes any July dates, open iflyglacier.com immediately and confirm the runway schedule. The closure runs Monday at 6 p.m. through Friday at 10 a.m. for four consecutive weeks — booking a midweek July flight into FCA means booking a flight that won’t operate.
- Step 2: Book Logan Pass shuttle tickets at Recreation.gov as soon as you have confirmed park dates. Peak July weeks sell out at the 60-day mark. Set a reminder and book on opening day. Download the ticket before you leave home.
- Step 3: If you are 62 or older and a U.S. citizen or resident, purchase the America the Beautiful Senior Lifetime Pass ($80) before you go. Buy it in person at any national park entrance to avoid the online processing fee. It covers entrance fees at every federal recreation site for the rest of your life.
- Step 4: Download the NPS Glacier app, offline maps, and all reservation confirmations before leaving cell coverage. Cell service disappears inside the park — especially on Going-to-the-Sun Road. A digital ticket that won’t load is no ticket at all.
- Step 5: Buy bear spray in Whitefish or Kalispell after landing — transportation regulations prohibit carrying it on commercial aircraft. Fill your fuel tank in town. Stock up on groceries and supplies before entering the park.
