A Private 200-Acre Estate in Mount Bethel, PA, Between the Poconos and the Lehigh Valley
At Chelsea Sun Inn, you don't rent a ballroom. You get the whole estate: 200 private acres overlooking the Delaware Water Gap, one wedding at a time, so the mansion and grounds belong to you and the people you love. We're 30 minutes from Easton, 40 from Bethlehem, and 90 from Manhattan and Philadelphia.
New for spring 2027: the Garden Atrium. A glass-walled reception space with glass doors, chandeliers and greenery, seating up to 300, with views of the mountains, the wishing well, lake and fountain, the forest, the stone mansion and the pool. It's a spring-through-fall space, included with your package at no extra cost for now. Atrium dates are limited.
Included in both packages:
• Five ceremony sites (Top of the Mountain, Wishing Well, Lakeside, The Grand Lobby and The Barn) with setup and a free rehearsal
• Decorated tent with dance floor, sweetheart table, lighting and chandeliers; 300 chairs, tables and linens
• Up to 300 guests outdoors, 75–100 indoors
• Event Manager, on-site staff, parking attendant and a tractor-pulled trolley
• BYOB with no corkage or markup; bring any licensed caterer at no fee, with chef's kitchen access
• Setup, breakdown and cleanup handled for you
• Your dog may walk the aisle; LGBTQ+, interfaith and cultural ceremonies welcome
• Free 2-hour engagement shoot on the grounds
Stay the night: the 1811 stone mansion, restored in 2025, has 13 suites that sleep 36. With The Wedding + Estate Stay, the estate is yours for 24 hours: afterparty at the pool, 20-person heated jacuzzi and fire pit (April–November), breakfast together, and checkout at 11 AM.
Honest pricing: 2027 venue packages run $3,598 to $15,942 with tax and gratuity included. Off-peak (November 18–April 30) is half the peak price, for weddings up to 70 guests. Every date is priced at chelseasun.com.
