The cascade of Gujuli (or Goiuri) is a vertical jump of over 100 m in height that has the Oiardo stream near the town of Gujuli, in the town of Urcabustaiz in the province of ?lava (Spain), about 30 km northwest Vitoria-Gasteiz, on the road between Orduna with Murgu穩a. The flow of the waterfall is almost nil during the summer, being the best times to enjoy it the spring and fall. The Oiardo creek is a tributary of the River Altube, which in turn flows into the River Nervion.
