The 85-mile (137-km) long Columbia Gorge NSA would be a national park if it weren't a critical transportation corridor. It features waterfalls, mountains, monoliths, terraces, resort towns, vineyards, orchards, and The River, harboring a plethora of fish and birds, and unique plants and invertebrates. In the early 1900s, Portlanders would drive their Model T cars along the Columbia River Highway to gaze at waterfalls. It was the first scenic highway built in America. There is said to be over 4000 waterfalls; many are hidden away, but many are just a short hike off the Historic Highway. On this tour you'll explore the western, rainforested, southern side of the Gorge, dubbed "waterfall alley" where we'll have you getting wet under a waterfall, peering over cliffs, and learning stories of the area only the locals know. Your guide will return you to your departure location at the end of the tour. Book our Discover Portland Half-Day Small-Group City Tour as well, and receive $10 cash back.
