ACES at Hallam Lake has ample room for events with great spaces both indoors and outdoors. Set on a 25-acre nature preserve, guests can enjoy beautiful scenery and wildlife as well as explore our indoor nature center. ACES staff is available to present programs to guests and visitors such as introducing our resident birds of prey or leading sunset beaver walks on the lake. We would be happy to recommend local caterers or other vendors if needed. Out of respect for the nature preserve, no amplified music or loud, boistrous activity is allowed and events need to conclude by 10pm.
