Grand Mesa Scenic Byway

CO 65 Interstate 70 at Mesa to Cedaredge, western Colorado

Sixty-three miles of paved state highway from I-70 up the Plateau Creek canyon and across the top of the Grand Mesa to Cedaredge — the largest flat-top mountain in the world, with more than 300 stream-fed lakes on it.

Does Grand Mesa Scenic Byway close in winter?

Open all year

CO 65 is a paved state highway, not a gated park road — there is no spring opening date on this one.

Storms shut it, the way storms shut any high state highway. The seasonal thing on the mesa is the visitor center, which runs from Memorial Day weekend to the last Sunday in September.

The drive

  1. Interstate 70 at Mesa

    The north end, where the climb up Plateau Creek canyon begins.

  2. The top of the mesa 11,000 ft

    Evergreen forest and open meadow at about 11,000 feet.

  3. Lands End Overlook

    Off the byway on Lands End Road, out at the western rim.

    Open Memorial Day weekend until the last Sunday in September.

  5. Cedaredge

    The south end, down off the mesa.

What's on the road

  • More than 300 stream-fed lakes on top, full of rainbow, cutthroat and brook trout.
  • Lands End Overlook is the view — the whole valley below, from the western rim of the mesa.
  • Services between Cedaredge and Mesa are limited. Fuel and food are at the two ends, not on the mesa.
  • In winter the mesa is snowshoe, ski and snowmobile country, which is a large part of why the highway is kept open.
