River Festival


Green River wouldn't be here today if it wasn't for our River. In the late 1860's the Union Pacific Railroad choose the make their headquarters in a town west of Green River, making Green River a desolate town.

When the Blacks Fork River dried up in the year of 1869, Union Pacific Railroad quickly moved their headquarters into Green River, as our river was flowing full of water. Were the railroad went the people followed, and the rest is history.

Join the Green River Chamber in the celebration of our amazing river! Always the three weekend in August, we host the River Festival, a fun packed two day event! This event has something fun for everyone!

The River Festival starts off at 4PM on the third Friday of August, where we have music, beer, vendors, our shrimp boil, food trucks, and once it gets dark, FIREWORKS!
