Boulder
Boulder, Colorado
Give Boulder 2 nights: one for Pearl Street and Chautauqua, one for the Flatirons or Eldora. Skip it as a Denver base — the bus is 1 h each way.
Boulder sits at the foot of the Flatirons, 24 mi (about 40 km) northwest of Denver, and is a college town built around outdoor sport: hiking, cycling, climbing and trail running start inside the city limits. It is expensive for its size, walkable in the centre, and best used as a 2-night stop on a Front Range trip rather than a day trip from Denver.

Etiquette, safety and scams
Etiquette
- Greeting: Handshake and 'hi, how are you?' — reply 'good, thanks'; avoid: Treating the question as a real health enquiry
- Restaurants: Tip 18–22% and wait for the check; avoid: Leaving without tipping
- Personal space: Keep an arm's length in queues; avoid: Standing close to strangers
- Politics and religion: Listen more than you speak; avoid: Opening with hot-button topics
- Smoking: Smoke only in marked areas; avoid: Smoking near doors or in parks where banned
Scams and watch-outs
- Altitude: 5,400 ft (1,650 m). Take the first day easy; drink more water than usual.
- Afternoon thunderstorms in summer — be off exposed ridges by early afternoon.
- School zones drop to 20 mph when yellow lights flash; red-light cameras are common.
- Parking near campus is ticketed aggressively; use city garages behind downtown buildings.
- Living and hotel costs run high for a city this size.
Boulder is a low-crime city by US standards; the real risks are altitude, summer lightning above treeline, and traffic around cyclists and pedestrians downtown.
