Mill Creek Ridge Preserve

Wasco County, Oregon

Columbia Land Trust

Fees: none

Activity: hiking

Elevation: 1040'-1504'

Current status (as of 7/19/24): not blooming

Notes: A.k.a. "Mill Creek Ridge Natural Area." It is also possible to access the preserve from the south (by parking on Mill Creek Road), but there are no official trails down there, the property boundaries are not always marked, and it means an extra 500' of elevation gain to get to the top of the ridge. However, the terrain on the south side is arguably more interesting, with several steep-sided gullies.

Peak wildflower bloom at Mill Creek Ridge Preserve is typically from late March through April into late May, but there may be some flowers blooming from early March until early June.*
