Boulder Book Store

A local favorite on the Pearl Street Mall, Boulder Book Store houses more than 100,000 titles over its expansive three floors. As soon as you walk in, you'll find an extensive section of recommended books, with thoughtful explanations from staff members. It's the perfect place in Colorado to go if you have no idea what you're looking for — but be prepared to spend hours on end browsing the collection.
