Corporate & Private Events
Looking for a premium experience for your team, clients, or organization? We offer custom private hikes with dedicated BHO staff, flexible scheduling, and optional catering on the summit.
All guided hikes begin at the base of Great Blue Hill and are led by trained BHO staff who weave together natural history, climate science, and the Observatory’s 141-year observational record. Every hike is different — the hill changes season to season.
Our guides cover topics including local ecology, geology of the Blue Hills, historical weather events recorded at the summit, and how the Observatory continues its unbroken observation mission today.
