Surveyor's Ridge Trail (OR)
This is a gorgeous trail that dips in and out between incredible views of Mt Hood from across the Hood River Valley. On a clear day, you can also catch views of the Washington state volcanoes (Rainier, St Helens and Adams). Depending on the season, there are likely to be fabulous wildflowers or golden larches. You'll marvel at how few other people you're sharing those views with, though the few folks you will see are probably mountain bikers.
