Ryuzu Waterfall, also known as "dragon head waterfall," is a picturesque spot in Nikko that gets its name from its dragon-like shape. Surrounded by trees that turn fiery red and yellow in the fall, it's one of the first places in Nikko to see autumn colors. You can enjoy the view for free from a small observation deck, and there's a walking trail along the river where you can take in more scenic views before continuing on to Senjogahara Marshlands. Just hop on a bus from JR or Tobu Nikko station to get there!
