What first-timers get wrong in Denver
Altitude is the recurring mistake, because 1,609 metres dehydrates you, amplifies alcohol and burns skin faster even in cold weather, so take a slow first day before driving into the mountains. The A Line train from the airport to Union Station is $10 and takes about thirty-seven minutes against a $60-plus rideshare. Local RTD fares are $2.75 for three hours or $5.50 for the day.
What's actually worth your time in Denver
The Colorado State Capitol's fifteenth step is engraved as exactly one mile above sea level, and the free dome tour beats several paid attractions nearby. Red Rocks Amphitheatre is open free to walk and run on non-show days, and locals do stair repeats there at seven in the morning. Union Station's restored hall is a bar, not a museum. Rocky Mountain National Park is ninety minutes northwest.
What things cost in Denver
RTD charges $2.75 for a three-hour pass and $5.50 for a day, but airport journeys are a separate $10 fare requiring an upgrade if you already hold a day pass. Denver Art Museum general admission starts near $22 for Colorado residents and runs higher for visitors. A RiNo brewery pint costs $7 to $9, and a smothered green chile burrito on Santa Fe Drive stays under $12.
Denver with kids, realistically
Altitude reaches children faster than adults, so expect headaches and short tempers on day one and push water constantly. The Children's Museum of Denver at Marsico Campus is built for under-eights, with a real fire truck and a bubble room. The zoo in City Park is walkable in half a day. The free 16th Street shuttle takes strollers, and the Cherry Creek trail runs below street traffic entirely.
When the weather turns in Denver
Denver weather turns within an hour, since summer afternoons build thunderstorms with real hail and spring snow can drop thirty centimetres then melt by Thursday. Indoors, Nature and Science plus the Art Museum and Clyfford Still fill two days between them. Union Station's Great Hall lets you sit in an armchair with a drink and no obligation to buy more. The Tattered Cover is the default wet afternoon.
