What kind of climate does Denver have?
Denver, United States has very hot summers, cold winters. Denver is a base camp, not the destination; locals ski Loveland or A-Basin, not Vail. LoDo is played out; RiNo and Baker have the real food and dive bars. Green chile smothers every breakfast burrito; ask for pork green over vegetarian. The RTD A-line from DIA to Union Station beats any Uber. Weed dispensaries are everywhere but public consumption is illegal; hotels enforce this. Altitude sickness hits day two, not day one; hydrate on arrival and skip alcohol the first night. You can read the detailed month-by-month breakdown on this page.
