This park is just north of Lake Oswego and west of Milwaukie. From Portland, take I-84 exit 297 and take Terwilliger Blvd east for 1.7 miles to a traffic circle (follow the signs to Lewis & Clark College). The second spoke of the traffic circle will keep you on Terwilliger Blvd. Go another .8 miles on Terwilliger to the entrance of the park (Caution County Listers: the southern edge of the park is in Clackamas County).

There are numerous trails in this fairly large forested park and it is a beautiful area to explore.


Habitat and Birds

Many daytime mountain species can be found here and this location should not be overlooked as a good daylight destination but Tryon is especially good for owls.  Northern Saw-whet, Barred, Great Horned, and Pygmy-Owl have all been found here (Source: Catalyst Publications, Birding Portland and Multnomah County, John Fitchen.) and Barn Owl and Western Screech-owl have been rarer finds.   One July day produced the following species: Cooper’s Hawk, Hutton’s Vireo, Pileated Woodpecker, Hairy Woodpecker, Northern Flicker, Warbling Vireo, Black-throated Gray Warbler (10+), Wilson’s Warbler (10+), Pacific-slope Flycatcher (10+), Band-tailed Pigeon, Swainson’s Thrush, Brown Creeper, Winter Wren, and several more.
