[Address] Haydn Valley is on the road to Yellowstone Lake in canyon village, about five minutes' drive from the mud spring mud volcano, friends don't miss it. [Features] Haydn Valley itself is beautiful. It is a valley, but it actually looks like a super large plain, with rivers and mountains in the distance, especially open and refreshing. The most important thing is that this is a holy place to see animals. There must be surprises when you leave early or return late. Because animals are almost foraging at this time. We see a lot of animals here, as long as you look carefully, there must be surprises.
