Stop in for a Sunset Beaver Walk at Hallam Lake on Tuesdays and Thursdays at 7:30PM, or yoga on the outdoor platforms at Hallam Lake on Tuesdays at 5:15PM. There is always something to do at ACES and our staff is available at all sites to answer questions and show you around. These programs are free for members, with suggested donations for non-members.
