🌍 About Denver
Denver sits at exactly 5,280 feet — the "Mile High City" is literal, and the altitude is real: you'll feel winded on stairs and one drink hits like two, so go easy the first day. The thing worth driving 15 miles west for is Red Rocks, a concert amphitheatre built into two 300-foot red sandstone slabs; even with no show on, the trails and acoustics are open and free during the day. In town, skip the downtown malls for RiNo, a former warehouse district now covered in commissioned murals and packed with breweries. Eat green chili — the Colorado pork version, smothered over a burrito, not a side bowl. Come September–October: warm days, aspens turning gold in the foothills, and thinner summer crowds. Skip mid-winter unless you're heading to the ski resorts.
