#9: 7 Mile Hill • 5.8 mi • 1444 ft

The Dalles really only has one truly big, fast, awesome road descent of any significant length and 7 Mile Hill is it. You stare down The Dalles and the Columbia River dead-ahead, 1400 feet below as you sweep into the gorgeous, grassy hillsides—then blast at warp speed toward it, only slowing for a few tight switchbacks along the way. After a couple fast minutes, you sweep left alongside the Badger Creek and follow the gurgling brook down to Chenowith. 

If you’re lucky, you’ll see a couple of very large dogs.

I absolutely recommend riding this road in the downward direction instead of up, but it’s also an efficient climb to get you towards Mosier or Ketchum Road.
