What are three of the best hikes in Portland? I want to keep two of the walks short: 5 miles or less, and ideally, they are loops. Please also include one long hike.
Hiking is a great outdoor activity. Here are two shorter, looping hikes, and one very long hike. 

1. Lower Macleay Park to Pittock Mansion Hike: A five-mile round trip that takes hikers through city streets and into a forest.
2. Blue Loop Trail in Mount Tabor Park: A three-mile round trip called the Blue Loop circles the park. Stairs lead to the summit of Mount Tabor.
3. Washington Park Loop Hike: The 30-mile Wildwood Trail starts near the Oregon Zoo, passes the Vietnam Veterans Memorial, ascends to the Hoyt Arboretum, and continues to the Portland Japanese Gardens.
