Key Takeaways for June

For families and day-hikers, lower-elevation zones like Apgar and Lake McDonald deliver reliable access, easier trails, and active wildlife viewing. For multi-day hikers, include contingency days for road or weather delays. Backcountry permits are required for overnight trips, and 70% of sites are reservable June 15–September 30 via Recreation.gov.
