The trail to Thunder Rock Cove in Samuel H. Boardman State Scenic Corridor is a short 0.8 miles with little elevation change, making it a great stroll along the Oregon coastal cliffs. From the trail there are great views to the north and south as well as down to Secret Beach, which is accessed via a spur from the trail to Thunder Rock Cove. But the main attraction is Thunder Rock Cove, a small cove sheltered by sheer cliffs complete with a natural arch and a very noisy sea cave.
When a large wave enters the cove, it wraps around into a sea cave set into the cliff. Large amounts of water and surrounding air are forced into the back of the cave, creating a lot of pressure. When the wave hits the back and when forces on the air and water cannot push any further, the wave and air are expelled backwards and create a thundering sound that reverberates through the rock on occasion. On a calm day this sound is still audible with the occasional wave, but it is much more pronounced during large swells and storms.
A profound concept originally envisioned by governor Oswald West, in 1967 the Oregon legislature ultimately realized his vision of making the entire Oregon Coast forever open to the public in a piece of landmark legislation titled the Oregon Beach Bill, officially making all 363 miles public land. "The People's Coast" is truly a one-of-a-kind coastline, a unique blend of mountains and rocky stacks, towering old growth forests, marine sanctuaries, tide pools and kelp forests, charming towns, historic fishing communities, world-class golfing, breweries, and simply jaw-dropping scenic beaches.
