The best time to drive Going-to-the-Sun Road in Glacier National Park is during the summer months, typically from late June to mid-September.

Weekdays and the shoulder seasons of late June and early September are less crowded, though weather can be variable. Always check current road conditions and weather forecasts, ensure you have a valid park pass, and be aware of any entry restrictions or vehicle reservation systems in place.

Best time to see wildlife

The best time to see wildlife at Glacier National Park is during hours when temperatures are cooler and human activity is lower. Because of this, dawn and dusk are particularly excellent for spotting animals like deer, elk, and bears foraging for food.

The prime seasons for wildlife viewing are spring and early summer (May to June) when animals are active after the winter, and it’s calving season for elk and deer. You might also see activity in the fall (September to October) when animals prepare for winter. The fall rutting season for elk and deer offers unique viewing opportunities as well.

Wildlife is more commonly spotted in remote, less-traveled areas of the park, particularly in alpine meadows, forest edges, and along rivers and lakes. For the best experience, be patient, follow NPS guidelines regarding distance from animals, and use binoculars or a camera with a zoom lens. By planning your wildlife viewing during these optimal times and seasons, you increase your chances of experiencing Glacier National Park’s diverse and abundant wildlife.

What is the most crowded month in Glacier National Park?

The most crowded month to visit Glacier National Park is typically July, due to several factors. During this time, the entire Going-to-the-Sun Road is usually open. The weather in July is generally warm and dry, making it ideal for outdoor activities such as hiking and camping.

Additionally, many families take vacations in July since schools are on summer break, which definitely contribute to higher visitor numbers. To make the most of your visit during this busy time, consider arriving early in the morning or late in the afternoon to avoid peak crowds, planning your visit on weekdays rather than weekends, making lodging and activity reservations well in advance, and exploring less crowded areas of the park, such as the Two Medicine or North Fork regions.

What is the best month to see the northern lights in Glacier National Park?

The best month to see the Northern Lights, or Aurora Borealis, in Glacier National Park is typically September. During this time, the chances of clear skies and geomagnetic activity align well, increasing the likelihood of witnessing this natural phenomenon. Here are some reasons why September is ideal:

  1. Geomagnetic Activity: Solar activity, which causes the Northern Lights, tends to be higher around the equinoxes (late September and late March), making these times more favorable for aurora sightings.
  2. Clear Skies: September often provides clearer skies compared to the summer months, which can be cloudier and rainier.
  3. Darkness: As days shorten and nights lengthen, there are more hours of darkness, essential for viewing the auroras.
  4. Less Crowded: The park is less crowded after the peak summer season, providing a less interrupted experience.

To maximize your chances of seeing the Northern Lights, it’s essential to find a location with minimal light pollution, such as the park’s more remote areas, and keep an eye on aurora forecasts.

Glacier National Park is a place of awe-inspiring natural beauty and ecological significance, attracting millions of visitors each year who come to experience its pristine wilderness and tranquil landscapes. Whether you’re hiking its trails, driving its scenic roads, or simply soaking in the views, the park offers an unforgettable experience for everyone.

Lava at Hawai'i Volcanoes National Park

Sulphur Banks is one of the most visually striking areas in Hawaiʻi Volcanoes National Park. If you've never seen the yellow sulfur crystals on dark lava rocks, you're in for a real treat. Earlier this year, Sulfur Banks was closed for a maintenance project and was not expected to open until December. However, due to the trail crew's hard work, they wrapped up construction a month early.
Here's everything you need to know about the new upgrades to Hawai'i Volcanoes National Park

The Sulfur Banks Trail, also known as Ha'akulamanu, has reopened upon the project's completion, which included a complete replacement of the boardwalk, benches, and railings. This area of the park hasn't seen much TLC since 2000, so this was a welcome upgrade. The new boardwalk is made from yellow cedar, which is strong and weather-resistant to all manner of sun, rain, and heat, so the National Park Service expects it to last another fifteen or twenty years.
