Because it’s there, you have to climb it! Located along the Columbia River on the Washington side (along Route 14 between Skamania and North Bonneville), 848-foot high Beacon Rock gives you a great panoramic view of the river and gorge. Plus Lewis & Clark paddled past this monolith in 1805 on their way to the Pacific, giving it the name Beaten Rock. The under 1-mile trail to the top was carved out in 1918 and is an amazing climb of switchbacks, stairs, bridges, and views.
It’s a steady climb from the parking lot to the top, so be prepared for a workout. There’s a railing, but hiking with small children would make me nervous.
