Mount Washington Auto Road Summit Observatory

At 6,288 feet, Mount Washington’s summit houses the weather observatory that recorded the world’s highest surface wind speed at 231 mph. The Auto Road — open since 1861 — climbs 4,618 vertical feet through multiple climate zones, from temperate forest to alpine tundra. The toll road is paved but steep (12% grades), narrow, and unforgiving. Weather can shift from sunshine to whiteout conditions in minutes, even in summer.

The road operates roughly May through October, weather permitting, with a hefty toll ($39 for car and driver in 2023). RVs and trailers prohibited. Cell service is spotty to nonexistent on the climb. The summit offers stunning 360-degree views on clear days, but visibility can drop to zero without warning. Bring layers — it’s typically 35 degrees cooler at the top.
