Best Seasons for Hiking
Best overall:
- April to May

These periods often bring comfortable temperatures and scenic trails, though exact conditions vary by region and year.
Autumn foliage is beautiful but crowded. Spring is usually easier for first-time hikers.
Spring Hiking
Spring hiking can bring flowers, mild air, and clearer trail conditions.
Watch for:
- fine dust
- chilly mornings
- dry trail closures in some areas

Pack layers and check air quality before mountain viewpoints.
Summer Hiking
Summer hiking is the riskiest for casual visitors because of heat, humidity, sudden storms, and slippery trails.
Avoid hiking during:
- heat alerts

- thunderstorm forecasts
If you hike in summer, start early, carry water, choose short routes, and turn back if weather changes.

Tips:

Always check official park information before hiking.
