Looking for unusual venues in Buskinhamshire? Host a gathering on a private island in the middle of the River Thames, where your guests arrive by boat. Set up a corporate retreat deep in the woods, where meals are cooked over open flames and served under the trees. If that’s not different enough, how about an event inside a historic railway station, where vintage locomotives line the platform? Or take things to new heights—literally—at a treetop adventure course where networking happens 30 feet above ground. Scroll through and find a venue that does things differently.
