Location: Fairmont Copley Plaza
138 St James Ave, Boston MA 02116

We hope you will join us at our 2025 Evening Expedition Gala on Wednesday, November 5, 2025. Our annual gala brings together over 300 corporate employees and local philanthropists from across Boston for an evening of celebration and community. Not only will you have the opportunity to expand your professional networks, you will also get to meet many of the inspiring young people whose lives have been forever changed by the experiences and the magic they shared at Cathleen Stone Island Outward Bound School.

Sponsorships start at $2,500 and include access to dinner, and a silent auction. Every dollar raised through this annual fundraising event will go directly toward supporting Cathleen Stone Island Outward Bound's core mission to build stronger, more equitable public-school communities through free experiential learning programs for Boston students.
