Explore Ape CaveExplore a chilly, pitch-black lava tube over two miles long. A short, paved, accessible trail beneath towering trees leads to a stairwell into the cave. The ¾ mile, one-way lower cave route is relatively easy and family friendly. For the more adventurous, the 1.5 mile upper cave route leads to a climb up an eight foot rock wall and scramble over rock piles, then an exit and a 1.5 mile above ground hike back to the parking lot.
Ape Cave is the third longest lava tube (2.5 miles long) in North America and the cave temperature is 42 degrees F/5.6 degrees C year-round. Make sure to bring two sources of light per person (a cell phone light is not bright enough), sturdy shoes, warm clothing, even in warm weather. In summer, Ape Headquarters, a small information station, offers lantern rentals, information and sales items to ticket holders.

About Ape CaveApe Cave was discovered in 1947 by a logger named Lawrence Johnson. However, the cave was not explored until the early 1950's when a scout troop, led by Harry Reese, lowered a team of scouts down a 17-foot overhang to the cave floor. Leaving footprints where no one ever had, these explorers were able to travel through a pristine lava tube full of fragile formations. Ape Cave was named by the Scout Troop in honor of their sponsor, the St. Helens Apes. This local group was made up primarily of foresters. The sponsor’s name, St. Helens Apes, may have come from an old term used for foresters in the area, "brush apes," or from the legend of Bigfoot.

June Lake
Offering picnicking opportunities on the shores of June Lake, this trail is a good choice for families and beginning hikers. June Lake was formed by a 2,000-year-old lava flow blocking a tributary of Swift Creek. The lake is located along the base of a basalt cliff over which a waterfall pours, replenishing the lake’s cold, clear water.
Start by gently climbing through a young forest, following the rushing sounds of a tributary of Swift Creek that flows from June Lake. The lake is soon reached providing a great place to picnic. Continuing, the trail climbs steeply for 0.25 mile to its junction with Loowit Trail #216. June Lake Trail #216B is the shortest access to Loowit Trail #216.

Trail of Two Forests
View lava casts from 1,900 year old trees. Road clear to site. A Northwest Forest, America the Beautiful Pass, or $5 in the fee tube is required.
This trail loops through two forests that stand side by side, but are separated in age by 2000 years. One forest is old-growth Douglas-fir and western red-cedar and the other is a young forest that was originally engulfed by lava flows from an eruption of Mount St. Helens over two millennia ago. This forest encompasses three-dimensional imprints of trees in the old lava beds called lava casts. The boardwalk trail loops through the two forests, and is kid friendly.
Driving Directions

Lava Canyon
In this landscape much more stark than the forest below, spectacular views await all visitors. There are three sections of the Lava Canyon Trail distinguished by increasing difficulty. The upper trail is accessible and paved to a waterfall viewpoint. This portion is the easiest and leads you past a series of interpretive signs, which describe the formation of the canyon. The trail begins from Lava Canyon Interpretive Trailhead.
Below the waterfall viewpoint the trail becomes more difficult; it is no longer paved and skirts high cliffs. This segment forms a loop, crossing the canyon on a 125-foot cable suspension bridge. THE SUPENSION BRIDGE IS CLOSED FOR THE 2019 SEASON DUE TO CABLE DAMAGE. The bridge provides spectacular views of the canyon below but may be unnerving to some hikers. The trail returns on the south side of the canyon, crossing a steel bridge upstream of the waterfalls and rejoins the paved trail.
The lower trail is most difficult as it descends steeply into the canyon. If you are uncomfortable with heights, this segment is not for you. Beginning at the suspension bridge, the trail crosses an exposed cliff face followed by a water crossing with a cable grab-line. A 30-foot metal ladder descends a vertical cliff providing access to the canyons deepest recesses and roaring waterfalls. The trail soon intersects Ship Trail 184B which climbs 0.2 mile to a viewpoint atop the Ship, a lava formation that overlooks a long series of waterfalls in the lower canyon. A few tenths of a mile further, the canyon begins to broaden and flatten as it approaches a large alluvial fan spreading into the Smith Creek valley. Here the Lava Canyon Trail ends where it intersects Smith Creek Trail 225. A car shuttle to the lower trailhead permits a one-way downhill hike.
Driving Directions
From Woodland, WA take State Route 503/Forest Road 90 east to the well-signed junction with Forest Road 83. Take a left on Forest Road 83 and follow for 12 miles to Lava Canyon Trailhead/Intepretive Site at the end of the road.
Windy Ridge
This site is south of Spirit Lake at the end of Forest Road 99. This site accesses the area devastated by the 1980 eruption and is a top location to view this area. Looking north, you see log-filled Spirit Lake topped by Mount Margaret. To the south you look upward at Mount St. Helens’ crater and lava dome.
Nearly everything in view is within the area decimated by the eruption. Encounter the blast’s full impact as you transition from green forest to standing dead forest to blown down forest. The landscape in this area is littered with sand and gray rocks from that event.
Windy Ridge Interpretive viewpoint provides access to Truman Trail #207 and Willow Springs Trail #207A.
Driving Directions
From Randle, WA travel south on State Route (SR) 131 until the road forks (1 mile). Stay to the right on State Route 131 which becomes Forest Road 25. Travel south on Forest Road 25 for 19 miles to Forest Road 99. Turn right on Forest Road 99 and drive 16 miles until it terminates at Windy Ridge.
