Align activities with safer, lighter-impact windows: winter avalanche checks, spring blooms, cool mornings in summer, and quieter ridgelines in autumn.

Winter
Stay on designated snow routes and review avalanche reports before heading out. Keep pets leashed and steer clear of secluded areas.
Check safety bulletin
Spring
Late spring is bloom season in many valleys: steer clear of muddy edges to protect trails, and head out at dawn for birdlife.
Summer
Begin early to reach glaciers, swim only in approved zones, and think about microspikes for early-season snowfields.
Autumn
Golden foliage and cooler mornings yield gentler hikes. Opt for quieter refuges and stay on durable trails.
