Glacier National Park is characterized by varying elevations, ranging from moderate to high altitudes. The park’s average elevation is approximately 5,230 feet (1,594 meters), with peaks reaching over 10,000 feet. This diverse topography offers visitors a range of experiences, from lower-elevation lakes to high-altitude mountain trails. Understanding the park’s altitude is crucial for planning visits, preparing for weather conditions, and managing potential health effects associated with higher elevations.
Is Glacier National Park Considered High Altitude?
Glacier National Park encompasses a wide range of elevations, making it a mix of moderate and high-altitude areas. Here’s a breakdown of the park’s altitude profile:

- Rapid weather changes
- Potential for altitude sickness symptoms
What Weather Conditions Can Visitors Expect at High Altitudes?
High-altitude areas in Glacier National Park experience distinct weather patterns:
- Summer: Mild days (60-70°F) but cool nights (40-50°F)
- Winter: Extreme cold (-10 to 20°F) with heavy snowfall
- Spring/Fall: Unpredictable, with potential for sudden storms
Key weather considerations for high-altitude areas include:
- Rapid temperature changes
- Strong winds
- Increased chance of thunderstorms
- Possibility of snow year-round
