At a minimum, any stop at this trailhead isn't complete without visiting the viewpoint. From the signpost at the trailhead, take the right fork for a quick stroll along the 250-foot flat, graveled path. It leads to a viewpoint above Beach 4 with a stunning 180-degree view along the coast. This short path to the viewpoint also has some magnificent nursery trees.
From the signpost at the trailhead, take the left fork for the main trail. There are several interpretive signs along the way where you can learn about local ecology. You'll quickly turn to the right and start the descent. The trail follows a small creek down the draw and is mostly wooden box steps with gravel. Enjoy the native coltsfoot and cow parsnip along the trail amidst more common rainforest flora.
The trail ends at a short bridge with driftwood flourishes that crosses to an uneven rock outcropping. From the rock, it's about a 4-foot drop to the sand. At this time, there's a rope tied to the bridge to help you climb up and down. There's no other structured or safe method to reach the beach. Wind, water and erosion can quickly change beach landscapes, but this rocky entrance provides a more sustainable access point.
Note that the only places to camp on the southern coast of the Olympic National Park are at the Kalaloch campground (3 miles from Beach 4) and the South Beach campground (6.5 miles from Beach 4). If you plan to adventure further along the beach, always make sure to check the tide times.
On the return ascent up the stairs, if you need to stop to catch your breath, there's a rustic wooden bench before the final turn.
Afterwards, don't skip a visit to the Tree of Life on the beach below the Kalaloch Campground, a couple of miles south of Beach 4 on US 101.
