Arrival day
Before Day 1. Denver is a mile above sea level, so give the group a gentle start.Details
From the airport
Denver International Airport sits far out on the plains, east of the city. A train runs from the terminal to Union Station downtown, and taxis and rideshares run too. Allow plenty of time, especially after a long flight with children.
The altitude
Denver is about a mile above sea level, and the national park climbs much higher. Take the first day easy, drink plenty of water and listen to your body. Anyone who feels unwell should rest and slow down, and a doctor can advise before you go higher.
Your car
Days 1 and 2 are easy without one. Collect a rental car for Day 3, since Red Rocks, Golden, Boulder and the national park are all easier by car. Check the rules and any entry arrangements for the park before you set out.
Two bases
Stay in Denver for Days 1 to 3, then move to Estes Park for the two park days. Beds in town can fill in autumn, so book early and ask where you can leave your luggage on the move.

Go whenMidday, with a walk along the creek.

MorningCheck ahead first
Trail Ridge Road
The high road across the park, climbing above 12,000 feet over open tundra. It is seasonal and can close for snow, so check ahead. Take it slowly and stop at the pull-outs.
Go whenMorning, once you have checked that the road is open.
Local tip The road climbs high and can close for snow, even in early autumn. Drive slowly, use the pull-outs and go back down if anyone feels unwell.
Pack a lunch before you climb, since the high stretches have few places to buy food. Eat at a pull-out with a view.
Local tip Bring warm layers, because the wind on the tundra is cold even on a sunny day.

EveningWorth the time
Moraine Park
A wide meadow in a glacier-carved valley where elk gather, especially around dawn and dusk. Watch from the roadside and keep a safe distance from the animals.
Go whenAround sunset (about 7:08 PM), when elk move through the meadow.
Local tip Watch from the road or a pull-out, and keep a safe distance from the elk. In autumn the males are loud and can be unpredictable.
If it rains. Alpine Visitor Center is covered, so keep it. Move Trail Ridge Road and Moraine Park to a dry day if you can.
Departure day
After the last day. The airport is far from town, so plan the way out the night before.Details
Leaving Estes Park
Leave the mountains after a slow breakfast on Day 6 and allow generous time for the drive down to Denver. Road work and weather can slow the mountain roads, so check ahead before you set out.
Returning the car
If you will take the train to the airport, return the car in the city first. Fill the tank on the way and ask your rental company about its return rules.
To the airport
The airport is a long way from downtown, and the train from Union Station is steady when the roads are busy. Choose the earlier option when in doubt, and keep snacks handy for the children.
