This is an easy paved trail in the Upper Geyser Basin that passes by some of the biggest geysers in the Upper Geyser Basin, coming to an end at Morning Glory Pool. Castle, Grotto, and Riverside geysers are among the main features you'll see along the way. Eruption predictions for Castle Geyser and Riverside Geyser are available at the Old Faithful Visitor Education Center. Didn't bring your own bicycle? That's not a problem. Bike rentals are available at the Bear Den Gift Shop located inside the Old Faithful Snow Lodge right there in the Old Faithful Village.
