Private Boulder Tour from Denver — Flatirons, Flagstaff Mountain & Pearl Street Stroll
Select participants and date
You arrive from Denver with the Front Range pushing itself into the windshield — a stepped horizon of pines and sandstone. The van eases up Flagstaff Road and the city below opens: a patchwork of ski‑white roofs in winter, a green sprawl in summer, and the Flatirons rising like sliced stone blades to the west. For four hours the tour moves at the pace of the land: brief hikes on well-worn trails, panoramic pullouts, and a threaded walk through Pearl Street where local vendors and CU Boulder students cross paths.

Adventure Tips
Acclimate to altitude
Boulder sits over 5,400 ft; take it easy on the first climbs and drink water before hiking to reduce lightheadedness.
Wear traction-friendly shoes
Fountain Formation sandstone can be smooth and slippery when wet — hiking shoes with good treads help on short ridge sections.
Time for light
Plan photo stops at sunrise or late afternoon when the Flatirons' textures and warm light are most dramatic and crowds are thinner.
Pack a reusable bottle
The tour provides a water refill in the van — bring a reusable bottle to stay hydrated and reduce waste.
Local Insights
Wildlife

History
Boulder grew rapidly in the late 19th century with the arrival of the railroad and the founding of the University of Colorado; the Flatirons' rock is part of the Fountain Formation deposited hundreds of millions of years ago.
Conservation
