Hike to the top of a mountain in Boulder for awesome views! Hike either the Sanitas Valley Trail or Mt Sanitas Trail; if running, we recommend starting from Centennial Trail Head and taking the Sunshine Canyon Trail to Lions Lair (see Trail Run Project for more information).
If staying for a weekday, this is only an hour drive from Boulder. Don't forget your park pass and your timed entry pass if going between 9am-3pm. Note: RMNP is crowded on the weekends, especially in the summer, and we do not recommend going on Friday or Saturday.
