Event details

See the dazzling spectacle of nesting herons, egrets and cormorants, and maybe even see one of our resident bald eagles! The preserve has controlled access during nesting season to minimize disturbances to nesting birds. The only way to view these amazing creatures at Lake Renwick during this time of year is to visit during these hours. Volunteers and staff will be at the viewing platform and visitor center to answer questions. 

Event requirements

No registration required.

Bringing your own binoculars or spotting scope is recommended. Park in the lot located off Renwick Road. Dogs and bicycles are not permitted in Lake Renwick Heron Rookery as it is a designated nature preserve. 

The viewing platform is accessible via a crushed limestone trail over uneven terrain. Anyone who requires an auxiliary aid or service to participate in this program should submit a request online no later than 48 hours before the program.
