Drive East Portal Road
Drive East Portal Road
East Portal Road is the only way to drive from the rim of the Black Canyon down to the Gunnison River without a rope. It is 5.2 miles of steep, windy pavement hitting 16% grade in spots - put the vehicle in low gear on the way down or you will cook your brakes. At the bottom you get river access, wayside exhibits on the Gunnison Tunnel and Diversion Dam, and a quiet campground. Allow 1-2 hours for a leisurely tour, and leave the big rig up top: vehicles over 22 feet are prohibited.
The only drivable route to the bottom of the Black Canyon - river access without a wilderness permit or a scramble down a draw.

Before you book
Is the drive worth it, or should I just stick to the rim overlooks?
It's a different park down there. The rim gives you the vertigo; East Portal gives you the Gunnison River at eye level, plus the Gunnison Tunnel and Diversion Dam exhibits. Allow 1-2 hours for a leisurely tour - cheap for the payoff.
Is the road safe for a nervous driver?
It's paved and two-way, but windy and steep - 16% grade in places. Put the vehicle in low gear so you're not riding the brakes, use the pullouts, and take your time. If steep mountain grades genuinely rattle you, this one won't change your mind.
Can I take my RV or trailer down?
Not if the rig is over 22 feet - those vehicles are prohibited on East Portal Road. Leave the trailer up top and take the tow vehicle down alone if it qualifies.
Does it cost anything or need a reservation?
No. No fees apply to the drive itself and no reservation is required - just the park entrance fee ($30 per private vehicle for a 7-day pass).
Can I bring my dog?
Yes, on a leash no longer than six feet - except downstream from East Portal Campground, where pets are prohibited. And never leave a pet in the car; interiors overheat within minutes even with windows cracked.
When is the road open?
Spring through fall. It closes in winter, typically from November to April, so check status before a shoulder-season trip.
