Beacon Rock is the core of an ancient volcano that has been exposed from the Missoula floods. The ice-age floods scoured the volcano away and left this 848 foot tall andesite plug.

Beacon Rock was named by Lewis and Clark on October 31, 1805. It was near Beacon Rock that Lewis and Clark first measured tidal influences on the Columbia River from the Pacific Ocean.

In 1811, Alexander Ross of the John Jacob Astor expedition called the rock Inoshoack Castle. The rock became known as Castle Rock until 1916, when the United States Board of Geographic Names restored the name back to Beacon Rock.
In the early 1900s, the Army Corps of Engineers planned to destroy Beacon Rock with dynamite. Railroad officials opposed the idea because they didn’t want the blasting to drop boulders onto the train tracks. Their opposition was enough to get the demolition stopped. Another idea was to use Beacon Rock as a rock quarry.

In the late 1910s, Henry J. Biddle purchased Hamilton Mountain, Biddle Butte, and Beacon Rock to preserve it. The trail to the top of Beacon Rock was completed in 1918. Biddle died in 1928 and in 1932 his heirs turned over Beacon Rock and Hamilton Mountain to the state for use as a park.

The first mile of the trail is wide and very well maintained. Just after crossing under the power lines there is a trail junction going on a gravel trail back to the upper parking lot. The first mile of the trail is used so much that I didn’t see a single plant growing in the middle of the path. After a little over a mile is Hardy Falls. The trail looks down on the falls and there is a side trail down to another overlook. Rodney Falls is reached soon after Hardy Falls, about 45 minutes from the trailhead. Take the short side trail to the left to the upper falls and the Pool of the Winds. Here the water surges through a narrow cleft and mist blows out of the opening. Back at the junction, the trail drops down and crosses Hardy Creek on a log bridge with railings. The sound of the water at the bridge is wonderful to listen to. The spring snowmelt sends cascades of water rushing down the rocks. The trail climbs some stairs up out of the valley of Hardy creek. From the top of the stairs, you can turn sharply left and follow the old trail up a couple of switchbacks and avoid the crowds. The main trail goes straight and shortly comes to a nice viewpoint of Beacon Rock and the Columbia River. From here, the trail gets steeper as it climbs towards the summit of Hamilton Mountain.

Bear right at the junction of the Hardy Creek trail and the Hamilton Mountain trail. This part of the trail is in the forest and the understory consists mostly of Oregon Grape, alders, and ferns. Like most trails in the gorge, area in the open and exposed to the sun, have poison oak. Be sure you know what it looks like to avoid getting the sap on you, your clothes, your equipment, or you pets. The sap can come off items that contact the poison oak and get on your skin.

There are several short side trails leading to overlooks of the gorge. One side trail leads through a narrow slot in the rock out to a narrow trail along basalt cliffs. Don’t trip here or you’ll roll over the edge. The main trail switchbacks up the side of the mountain. There are incredible sweeping views of the gorge to the west and to the south. Another side trail leads out to an overlook where you can enjoy the views, if it isn’t too windy.

This part of the trail is open and the slopes are speckled with wildflowers in the spring. When you reach the summit of Hamilton Mountain, the side trails leading towards the gorge go steeply downhill and peter out without providing any views. These trails aren’t worth exploring. Instead, take the trail to the left which drops down, leads to other viewpoints, and goes along “The Saddle” to a junction of old Forest Service roads.

Take a left at the junction at the old Forest Service Road and follow the road down to the first switchback and take the trail marked Foot Traffic Only. This trail is “Don’s cutoff trail” and will lead back to a Forest Service road along Hardy Creek. Follow the road downstream along Hardy Creek to a small picnic area and the Hardy Creek trail. The trail enters the forest at the left edge of the picnic area. If you cross Hardy Creek, you are going the wrong way.

The trail gently gains elevation above Hardy Creek. After about ½ mile the trail starts descending again down to the Hamilton Mountain trail junction. Turn right at the junction and follow the main trail back across Hardy Creek and perhaps take a last look at the Pool of the Winds.

After about a mile is a junction going uphill. Turn right here and walk along past a bench and into the woods. Soon the trail passes a plaque. Be sure to check out the stump the plaque is mounted on.

Turn left shortly after the plaque and take the .2 mile Little Beacon Rock Trail to Little Beacon Rock and a spectacular view of Beacon Rock framed by fir trees. Return back to the junction, turn left, and walk down the trail downhill through the campground and return to the parking lot.

This hike is relatively safe for youngsters as long as they stay on the main trail. Be aware there are tall cliffs just off the trail.

Enjoy the photos!!
