Picnic on the Preserve: Membership Dinner 2024

ACES members are invited to our annual membership dinner, Picnic on the Preserve, on Monday, June 10 at 5:30pm. Kick off the summer season with a community celebration at Hallam Lake with drinks, live music and a delicious dinner with food from Rock Bottom Ranch.

Tickets will be made available via email in early May via email. To verify that your membership is current, please contact Jack Osius, ACES Development Coordinator, at josius@aspennature.org.

This event is all about celebrating our wonderful community of ACES members. Become a member today or renew your membership to receive the registration link. 

Please walk, bike, bus or carpool to Hallam Lake whenever possible, as parking is extremely limited. If you must drive, please park efficiently in the ACES lot. Overflow parking for Hallam Lake is available in the West End (2 hour free parking) with an easy walk down to the nature center.


A special thank you to our event sponsor, Obermeyer Wood!
