Open Space & Mountain Parks is offering a very fun hiking option this fall – Howl-o-Ween – a fun hike for dogs and their people. Visit fun educational stations amid the beautiful colors of fall while your dog trick-or-treats for tasty dog snacks and toys along the way. Costumes – dog and human – are encouraged. This hike is happening on Saturday Oct. 25 from 11 – 2 pm. Meet at the Cherryvale Trailhead, 66 S. Cherryvale Road. https://bouldercolorado.gov/osmp/cherryvale-trailhead
