Hikes and Events Open Space Calendar

Celebrate the first full moon of 2026 by hiking with volunteer naturalists in a park that usually closes at sunset. We’ll meet at the picnic shelter at 4:30 p.m., enjoy both the sunset and the moonrise, then meander on easy trails under the full moon. We’ll observe, talk about what we see, and maybe share poems or stories. Bring a headlamp, preferably with a red light, and layers for the weather. Registration required.

When the temperature drops, and the snow settles in, what birds stick around and call Boulder County home? The bird species that reside in the area during the winter face risky challenges and have adapted unique behaviors and physiology that help them meet these challenges and survive. Register on the City of Boulder’s Age Well Center website. Registration required. Register .tribe-events-c-subscribe-dropdown{display:none;}

Hop in your car with friends and family and join us for a driving tour of some of Boulder County’s best areas to view birds of prey. Follow the tour map to designated stops with volunteer naturalists, search the skies for raptors, learn about their habitats and behaviors, and work on your observation and identification skills. Location shared upon registration. Registration for most programs begins on the 20th of the month before the event. Registration required. Register .tribe-events-c-subscribe-dropdown{display:none;}

Join volunteer naturalists on a mostly flat, 3-mile, out-and-back snowshoe walk to an aspen grove at Caribou Ranch. With the leaves gone, we can enjoy the subtle colors of winter and the stories in the aspen bark. While resting among the aspen, we will practice mindful observation. We’ll take time to reflect together on what we’ve observed, what we know about aspens, what remains unknown, and what we can still learn from nature. Registration required.
