Estes Park is easy enough from Denver, but the trip gets easier when you make the airport, drive, and seasonal-road decisions before you are already tired.
Arrival map
Most flights use Denver International. US-36 through Boulder and Lyons is the straightforward approach; US-34 through Big Thompson Canyon is the scenic alternative when daylight and road conditions cooperate. Use live directions for traffic and closures.

From DEN, the fastest published approach uses E-470, I-25, CO-66, and US-36 from Lyons. Through-Boulder routes also reach Lyons on US-36. Treat every drive time as approximate because weather and Front Range traffic can change the choice.
Summer mostly means traffic and timed-entry requirements. Shoulder seasons and winter add weather, road conditions, and the possibility that your ideal scenic route is not the one the day will actually allow.
Denver to Estes Park
DEN is the main commercial airport for the trip. After the drive, use Estes for dinner, Lake Estes, or a short riverwalk instead of forcing Bear Lake on tired legs.
US-36 reaches Estes through Lyons; US-34 reaches town through Big Thompson Canyon from Loveland. Choose with live traffic, weather, road status, and remaining daylight in view.
Before bed, confirm timed entry, road status, layers, breakfast, and the corridor you actually want. That quiet prep is what makes the next morning feel easy.
