5K Run




Flat Rock Brook's 6th Annual 5K Run
Sunday, August 6, 2017

Flat Rock Brook will hold its annual 5K “Run in the Wild” trail run on August 6th.  The run begins at our visitor center and after a short street run enters the shaded and forested trails of our 150-acre preserve.  The run provides participants with the uncommon experience of trail running through a nature preserve.

Our 5K is sanctioned by the USA Track and Field Association. 

I thought it was a wonderful event! The volunteers and staff were helpful and enthusiastic, and the course was very pretty! It was a really nice event. I will definitely return next year and bring friends!

New Program: Adopt-a-Raptor

eastern screech owl

One of Flat Rock Brook's most popular exhibits is our aviary where we house 6 birds of prey that are all unable to be released into the wild.  Their home is now Flat Rock Brook, where our staff provides the care that they need.  Our birds act as animal ambassadors and help us teach thousands of people each year about protecting and respecting wildlife.  Help support our special birds!  Various adoption levels allow our supporters to provide food, enrichment, and enclosure maintenance for 1 month, 3 months, 6 months or 1 year.  Each level offers different benefits, such as a photo and certificate of adoption for your raptor or even a meet and greet!  Choose your raptor today!  
Visit Flat Rock Brook Adopt-a-Raptor to adopt and learn more.

Flat Rock Brook wants to recognize and extend a big "thanks" to our first adopters!
