Fitness Hike - Ridge Park

Looking for Native Animals in Your Backyard: Round Canyon

There are critters in your backyard: big ones, little ones, furry ones, ones with feathers, and ones with scales. They go about their business and pay little attention to you. In fact, they would rather not be bothered unless you were a tempting morsel of food. Round Canyon is teeming with wildlife, and waiting for you to experience the solitary bobcat, the elusive ring-tailed cat, the mighty great horned owl, and playful ground squirrels, among many others.

The hike will average 2-3 miles round-trip at an easy pace with lots of discussion about wildlife along the way. This program is for participants who would like a slower-paced hike. Wear comfortable clothes and sturdy shoes and bring water for the hike.
