Main Corridor is a climbing area in Washington's Columbia Hills State Park, within the Columbia River Gorge National Scenic Area. The land is managed by State Park and Recreation, and the corridor sits right alongside two other climbing areas, Amphitheater and Horsethief Butte, which are each about 0.1 mile away. Late spring and early fall are the most comfortable times to visit. Typical averages from a nearby weather station in The Dalles show May highs around 73°F and September highs around 80°F, with only a few wet days in each month. July and August average highs near 88°F, and winter brings highs in the low 40s and rain on about 14 days a month. The Horsethief Butte Trail starts about 0.1 mile away, and the Eightmile Alternate Trail and Vista Loop Trail are both within about 2 miles. Across the river in Oregon, the Lower Bench Trail is roughly 6.7 miles off.
