recommendations for a work-away-from-home week

i’m staying in boulder for a few days (wed-sat) in may but i have to work remotely during that time. my work is located in the eastern time zone, so i have to be online until 3pm. what are some recommendations for places to hike and sight-see that i can get to and enjoy before dark? i’m just not familiar with traffic, how far away parks are, how busy parks can get, etc.
