Take 101 north of Olympic National Park toward the coast. Get off on La Push Road and head towards the town of the same name. The trailhead, which you'll find a couple minutes before you reach the town, begins a mile long hike through the temperate rainforest that will lead you to the rugged coastline and to Second Beach.
Be sure to protect your gear on Second Beach due to the fact that the salty sea spray will inevitably find its way onto everything.
This photograph was taken on Second Beach in Olympic National Park. It's a beautiful, secluded location that is well worth the hike to view. I released the shutter moments before the cold water swept past my feet. It's amazing how fast the Pacific tides roll in on the Washington Coast. Within just a couple minutes, the water was lapping well over my knees.
