We wouldn't be true Coloradoan's if we didn't recommend a hike while you're here! Starting at the Chautauqua Trailhead, you can access many trails that will take you around the Flatirons - the most iconic landmark in Boulder. There are trails of varying difficulty that branch from that trailhead. If you're not local to Colorado and interested in checking this out, let us know so we can help prepare you and steer you in the direction of some suitable trails! This park has a big open meadow along with the cutest general store and great views of the Flatirons, so still worth visiting even if you're not in a hiking mood. Consider taking an Uber or the Park-to-Park shuttle (it's free!) to the park as parking can be tricky and expensive. Let us know if you want more info on this!
You absolutely can't go wrong walking Pearl Street! Boulder's adorable and hipster downtown is 4 blocks of restaurants and shopping. Check out the link for lots of information on what's there to see. We recommend taking an Uber to that general area since street parking can be hard to come by, and you can walk around from there.
