Glacier National Park Rocky Mountains, USA Travel Guide
Glacier National Park experiences distinct seasonal climates, each bringing its own set of conditions. Summer (Late June - Early September) has the warmest temperatures, generally ranging from 60-80°F (15-27°C) during the day. Nights are cool, often dropping to 40-50°F (4-10°C), especially at higher elevations. Precipitation mostly happens as afternoon thunderstorms, which can be sudden but often brief. This brief window is when all park roads and facilities typically operate at full capacity, granting the most comprehensive access.
Fall (Mid-September - October) has crisp days, with temperatures typically between 40-60°F (4-15°C). Nights grow cold, frequently dipping below freezing. Precipitation increases, bringing a higher chance of rain and even early season snow, specifically at higher elevations. Many park services begin to close down during this period. Winter (November - April) transforms Glacier into a serene, snow-covered landscape. Temperatures are cold, often ranging from 20-30°F (-6 to -1°C) during the day, dropping well below freezing at night. Spring (May - Early June) sees rising temperatures to 40-60°F (4-15°C), snowmelt dominates. Trails become muddy, and rivers swell with runoff.
Hiking: Mid-July to early September offers the best window, as most high-elevation trails clear of snow and open. Check trail status carefully for strenuous hikes, as lingering snow or early season closures can influence access. Scenic Drives: Early July to mid-October generally marks the period when Going-to-the-Sun Road fully operates. This varies yearly based on snowmelt and plowing efforts. Check the NPS website for exact opening and closing dates, as this road is a centerpiece of any visit. Wildlife Viewing: Dawn and dusk in the shoulder seasons (June, September) and early morning or late evening in summer are often the best times. Animals are more active during cooler parts of the day. Many Glacier and Two Medicine areas are notable prime locations for spotting moose, bears, and bighorn sheep. Boating/Kayaking: July and August present optimal weather conditions for enjoying the park's lakes. Rentals are available, or you can bring your own non-motorized craft. The water stays very cold, even in summer.

Entry into the United States varies based on your country of citizenship. U.S. Citizens only need valid identification. Canadian Citizens need a valid passport or enhanced driver's license/NEXUS card. Citizens of Visa Waiver Program (VWP countries) can stay for up to 90 days for tourism or business with an approved Electronic System for Travel Authorization (ESTA) online prior to travel. An ESTA application goes through the official U.S. Customs and Border Protection website; apply at least 72 hours before departure. Other nationalities generally need a B-2 tourist visa, which demands an online application, a non-refundable fee, and an in-person interview at an U.S. Embassy or consulate. Processing times vary for B-2 visas, so apply with ample lead time.
Always keep your travel documents secure and accessible. A valid passport is required for all international visitors, valid for at least six months beyond your planned departure. Carry printouts or digital copies of your approved ESTA or visa confirmation. U.S. Immigration officers may request proof of your intent to depart, typically a confirmed return or onward ticket. Proof of sufficient funds to cover travel and living expenses, like bank statements or credit card limits, may also be necessary.

The official currency of the United States is the United States Dollar (USD or $). ATMs are widely available in gateway towns like Kalispell, Whitefish, Columbia Falls, St. Mary, and East Glacier Park Village. These offer the most straightforward way to get cash. Currency exchange services are rare outside major international airports in larger U.S. Cities. It is not generally advisable to exchange foreign currency at small local banks or kiosks, as they often have unfavorable rates.

Camping is the most economical. In-park sites ($20-50/night). Budget motels ($80-120) or mid-range hotels ($150-250) outside the park are often more affordable than in-park lodges ($200-800+).
Self-prepared meals from groceries save significant funds ($30-50/day). Purchase groceries in larger towns like Kalispell for better prices and selection. Casual dining ($15-30/meal) is an option.
Rental cars ($50-100/day plus gas) offer flexibility. The free park shuttle on Going-to-the-Sun Road reduces gas and parking stress within the park. Park entrance fees apply ($20-35 for 7-day pass, $80 for America the Beautiful annual pass).
