Who doesn’t love a trip to the Mountain West in the summertime? I grew up in the Rocky Mountains and have always loved hiking, summer walks, and mountain campouts. I know Frontier Airlines isn’t the best, but hey, it’s hard to beat nonstop flights for under $100. Ever wanted to try mountain biking or mountain lake swimming? I can’t recommend this one enough!

A trip to Denver gives you the best of both city and nature. Whether you want a relaxing getaway or an outdoor adventure, it’s easy to do both.

Travel Notes: The Essentials

Our Denver Picks:

  • Union Station – easy stop for a casual meal or coffee, central downtown location, and good for a relaxed walk before exploring nearby spots.

  • City Park – wide open paths, skyline-and-mountain views, and a convenient base near both the zoo and museum.

  • Dairy Block / LoDo – walkable area with quick dining options and a fun downtown feel without needing a packed schedule.

Family Activities:

  • Denver Zoo Conservation Alliance – a classic family stop with daily hours and easy planning for a half-day outing.

  • Denver Museum of Nature & Science – great for hands-on exhibits, planetarium add-ons, and an easy indoor option if you want a slower-paced day.

  • Red Rocks Park & Amphitheater – scenic, iconic, and family-friendly on non-event days; the Trading Post Trail is a popular short option, though parts of the terrain are rough.

Easy Day Trips:

  • Golden – close to Denver, with a small-town feel, family activities, creekside areas, and easy mountain-town energy without going too far.

  • Boulder – good for a laid-back day with shops, outdoor scenery, and several kid-friendly things to do.

  • Georgetown Loop Railroad – a fun mountain day trip about 45 miles west of Denver, with historic train rides and strong family appeal.

FareBud Tip: Book zoo, museum, and train tickets ahead when possible, start outdoor activities earlier in the day, and mix one big attraction with one easy neighborhood stop so the day stays fun without feeling rushed. Red Rocks also has different access hours on event vs. non-event days, so check that before you go.

Happy Travels!
