We are headed to Boulder in July for a vacation sans children! My husbands's all time favorite beer is Hazed and Infused, a trip to Boulder Brewing Company has inspired our trip. We plan to fly into Denver and we have reservations at the Quality Inn in Boulder. We are wondering if we should get a shuttle from Denver to Boulder and then walk everywhere we want to go.Is that possible or is it too far?(Quality Inn does off bike rentals.) Or should we rent a car out of Denver? Or perhaps we get shuttled to Boulder and then rent a car out of Boulder. We plan to visit Pearl Street, tour some breweries and perhaps explore some canyons. Any input would be appreciated!
