Blooming in forested areas: Beargrass (Xerophyllum tenax), Broad-Leaf Star Flower (Trientalis latifolia), Spotted Coralroot (Corallorrhiza maculata), Inside-Out Flower (Vancouveria hexandra), Thimbleberry (Rubus parviflorus), Hooker's Fairybell (Disporum hookeri), Western Serviceberry (Amelanchier alnifolia), Candyflower (Claytonia sibirica), Star-Flowered Solomon's Seal (Smilacina stellatum), False Solomon's Seal (Smilacina racemosa), Columbia Windflower (Anemone deltoidea), Inside-Out Flower (Vancouveria hexandra), Bunchberry (Cornus canadensis), Western Columbine (Aquilegia formosa), Vanilla Leaf (Achlys triphylla), American Vetch (Vicia americana), Stream Violet (Viola glabella), Fringecup (Tellima grandiflora), Western Meadowrue (Thalictrum occidentale), Foamflower (Tiarella trifoliata). Although none were yet blooming, there will be dozens (if not hundreds!) of Tiger Lilies (Lilium columbianum) in the near future.

Blooming in meadows and rocky areas: Northwest Balsamroot (Balsamorhiza deltoidea), Harsh Paintbrush (Castilleja hispida), Blue-Headed Gilia (Gilia capitata), Spring Gold (Lomatium utriculatum), Columbia Gorge Lupine (Lupinus latifolius var. thompsonianus), Western Wallflower (Erysimum capitatum), White Western Groundsel (Senecio integerrimus var. ochroleucus), Stonecrop (Sedum sp.), Upland Larkspur (Delphinium nuttallianum), Small-Flowered Blue-Eyed Mary (Collinsia parviflora), Catchfly (Silene sp.), Spreading Phlox (Phlox diffusa), Rock Penstemon (Penstemon rupicola), Subalpine Mariposa (Calochortus subalpinus), Small-Flowered Penstemon (Penstemon procerus), Annual Agoseris (Agoseris heterophylla var. heterophylla), Wild Strawberry (Fragaria vesca), Field Chickweed (Cerastium arvense), Oregon Sunshine (Eriophyllum lanatum), and Olympic Onion (Allium crenulatum).

Driving directions to trailhead can be found here. Some spots may be tricky for a normal (low clearance) passenger vehicle.

Hike information can be found here. Most of the wildflowers can be viewed within the first three miles of the hike. I recommend continuing at least one mile beyond (north of) Grassy Knoll.
