For the hiker who wants to stay within the city, Tryon Creek State Park, in south Portland near Lake Oswego, is incredibly well maintained. The trails are not very long, but they are well connected, so making loops is very easy. There are 8 miles of trail total, offering excellent opportunities to catch glimpses of wildlife and wildflowers in the spring.
The Columbia River Gorge has a wide variety of hikes, including the hike from Triple Falls to Horsetail Falls, which features some of the most beautiful and impressive falls in the area, including one that hikers can walk behind. For a more challenging hike on Mount Hood, Paradise Park is filled with a multitude of wildflowers in the summer, along with canyons, waterfalls, and views of Mount Hood along the way. It is a 12-mile hike and more than worth the work for the views of and from this alpine park.
