Parks Galore! by xeberus
Portland has tons of them! The best known to visitors because of the Rose Gardens and Japanese Gardens is Washington Park, but some others that you may want to check out are:The South Park Blocks between PSU and Taylor St with lots of trees, statues, the Art Museum, churches, etc.
Mt. Tabor, our own urban volcano! Don't worry, she's sleeping soundly. And from the top you can take in great views of the city both towards downtown and to the east to Mt. Hood. There are also some lovely resevoirs on Tabor.
Council Crest: This is the highest point in the city and on a clear day you get a wonderful view over the urban area and out to many of the High Cascades.
Laurelhurst Park: A lovely large urban park with a lake and great landscaping.
Forest Park: Over 70 miles of trails for hiking, biking, and horse riding in the woods, totally within the city limits!
Waterfront/Esplanade: Enjoy the calming waters of the Willamette up close.
