About Trillium Woods

Trillium Woods is a woodland wedding venue set among trees, walking trails, boulders, Lake Agawam and Slippery Rock Creek. Its amphitheatre offers an outdoor ceremony setting with bench seating, a center aisle, electrical access and creek-and-rock scenery. Receptions can be held in a 4,000-square-foot tent seating up to 170, with room for a dance floor, or in the enclosed, climate-controlled lodge, which has lounge seating, patios, restrooms and a caterer’s staging kitchen. A yard with a firepit and seating provides additional outdoor gathering space. Full weddings are offered May through October for up to 170 guests; micro weddings run November through April for up to 50. Getting-ready spaces vary by wedding day, and couples may have access to a private honeymoon suite in the Cabin or Cottage. Medure’s Catering is the exclusive caterer. The venue provides tables and chairs, event staff for cleaning and, if needed, the ceremony-to-reception furniture transition; golf-cart assistance is available. The venue lists about 40 parking spaces with overflow parking, handicapped parking and restrooms. The amphitheatre is not accessible to all guests, though an area is available for guests needing assistance to view the ceremony.
