Mount Defiance is the steepest sustained paved road climb in Oregon and a genuine test of what the Pacific Northwest's most serious cyclists are made of. Rising from the Columbia River level (30m) near the town of Hood River to the summit fire lookout at 1,225m, the Mount Defiance Road gains 1,143m over 11.2km — an average of 10.2% that places this in the same physiological category as the hardest Alpine climbs despite its modest summit elevation. The lower section through cherry orchards above Hood River averages 8-9%; the middle section through dense Cascade forest is consistently 10-12%; the final 2km on the service road to the summit fire lookout touches 16-17% on unmaintained pavement. The grade is relentless throughout — there is no recovery on this climb. What awaits at the top: complete solitude, a locked fire lookout, and a view west down the Columbia Gorge to Portland and east to Mount Adams in Washington that justifies every cruel metre of the approach.
Pro Tip
Mount Defiance is best ridden with fresh legs in the morning — this is not a second climb in a multi-climb day. Gear down further than intuition suggests at the bottom: what feels sustainable at sea level on a 5% grade is not applicable to 10% average at any point in the climb. Hood River has several excellent pre-ride breakfast spots: Broder Nord and Grateful Bagel both open at 07:00. The descent via the same road requires extraordinary care — the maximum gradient on the descent is 17% and the road surface on the upper fire access section is rough.
