Easy 1-mile walk along the beach. Fall asleep to the calming ocean. Massive rocks along the shoreline. Coastal forests. Campfires permitted (only driftwood).
Before you start this hike, you'll need to pick up a permit at the Wilderness Information Center in Port Angeles, WA - (360) 565-3100. The trail itself starts at Rialto Beach, which is at the end of Mora Road in La Push. There's a large parking lot for overnight campers so there shouldn't be any issues finding a spot.
Once you start heading north along the beach, there's no trail. The first noticeable landmark you'll come across is Ellen Creek (about .4 miles). Camping is officially permitted as soon as you cross the creek. For the next 0.6 miles, you'll notice a lot of established campgrounds towards the edge of the beach and forest. To reduce the impact of the area, I'd suggest picking one of these spots. Be aware, you'll need to properly store your food in a bear canister at night (mainly for raccoons, not bears).
If you set up camp before the big rock, make sure you take a stroll down to it for sunset. A massive ray of light shoots through the hole, creating a great beam of light. If the tide is low, try navigating around the outside to the beach on the other side. This was probably my favorite area since it was littered with driftwood and not too many people ventured over there.
