Blue Hill Observatory & Science Center · Milton, MA
Let's climb for climate, for the next generation,
and for a better tomorrow.
Earth Day 2026
More Than a Climb
The Earth Day Climb for a Better Tomorrow is the Blue Hill Observatory's signature annual celebration—a community gathering that combines the simple power of hiking with a profound commitment to climate education and environmental stewardship.
Ascend Great Blue Hill and join hundreds of community members at the historic Blue Hill Observatory. Along the way, you'll connect with others who believe the next generation deserves a healthier planet—and the chance to be part of shaping it.
Too many students grow up without access to inspiring outdoor spaces or real-world science experiences. Your climb changes that. Proceeds fund field trips, internships, mentorship, and career pathways that open doors for young people who've been left out.
