Hike Description

The Oregon Caves National Monument is one of the overlooked jewels of Oregon; even more overlooked is that, in addition to the Oregon Caves Loop Hike, you can take a trail that leads around the perimeter of the monument taking in Siskiyou Mountain woodlands and meadows and, surprise, Oregon’s largest Douglas-fir in terms of girth, the Big Tree, with a diameter of 13 feet. It is worth spending the time to do this short loop, enjoy the ambience of the Oregon Caves Chateau, a classic national park lodge, and take in the caves themselves.

From the day-use parking area, walk along the road until you reach the visitor center/gift shop. Head up between buildings to reach a junction and go left on the Big Tree Loop. Hike along the trail under typical Siskiyou mixed forest of Douglas-fir, canyon oak, tan oak, big-leaf maple and ocean spray. In early summer, wildflowers are profuse, including Siskiyou iris, woodland phlox, yerba de selva, blue-eyed Mary and the odd-looking ground cone. At a switchback, reach the Big Tree-Old Growth Trail Junction and go right.

Reach a second switchback at the monument’s water tanks. Keep heading up, and pass the Monument boundary to enter the Siskiyou National Forest. Look for Pacific madrone and manzanita bushes in this area. Enter an old growth coniferous forest composed mainly of white fir (the southern version of grand fir), Douglas-fir and sugar pine. The coniferous forest also marks the sudden transition from a marble substrate to argillite. Continue through the forest in a relatively open understory of young white fir and rhododendron. This area is a veritable garden of woodland blooms, including trillium, woods violet, deer’s-head orchid, bead lily, twin flower and wild ginger. Pass a rocky knoll and note the old Port Orford cedars in the forest mix. Cross lush Panther Creek, with its dense thickets of lungwort, thimbleberry, bleeding heart, and waterleaf, and reach the fenced platform at the Big Tree, an ancient Douglas-fir, trimmed by lightning strikes but 13 feet in diameter.

Above the Big Tree, pass below Waterfelt Spring, which harbors more lush thickets and reenter coniferous forest. Rise to reach the Big Tree-Mount Elijah Trail Junction, the latter trail also leading to Bigelow Lakes. From here the trail drops steadily to pass through two wildflower meadows. Arrow-leaf groundsel, stickseed, columbine, false hellebore, horsemint, cow parsnip and numerous other blooms decorate these slopes. Switchback down to cross the second meadow again before entering more coniferous forest. At a second switchback, you’ll cross and recross a creek. Continue down among Douglas-fir, white fir, and a few Port Orford cedars. Make two short switchbacks before you reach the Big Tree-Cliff Nature Trail Junction.

Go left here on the nature trail, which has interpretive signs on the nature and geology of the region. Pass a bench and then switchback before reaching Vista Point for a grand view towards the Illinois River valley. Marble outcroppings vegetated by green-leaf manzanita characterize this rim. The trail heads down and makes three short switchbacks before reaching the Oregon Caves Exit, the artificial outlet for guided groups to leave the cave. Make one more switchback below the cave exit to reach the cave entrance and Oregon Caves Chateau.
