The snow melts earlier at Tire Mountain than it does in the Cascades, which makes this a terrific wildflower destination during the first half of June. On clear days you will also enjoy fine views of the Cascades from along the trail.

The trail passes through alternating sections of mist-shrouded old-growth forests and open meadows, which means that there is a fine diversity of species. In the meadows, you will see Menzies' Larkspur (Delphinium menziesii), Deltoid Balsamroot (Balsamorhiza deltoidea), Rosy Plectritis (Plectritis congesta), Cardwell's Penstemon (Penstemon cardwellii), Cat’s Ear (Calochortus tolmiei), Scalloped Onion (Allium crenulatum), Sulphur Flower Buckwheat (Eriogonum umbellatum), Bluefield Gilia (Gilia capitata), Common Camas (Camassia quamash), Harsh Paintbrush (Castilleja hispida), Yellow Monkeyflower (Mimulus guttatus), Oregon Sunshine (Eriophyllum lanatum var. achillaeoides), and no less than five different members of the Lomatium family.
