Look and Tremble, sometimes Look and Tremble Shoals or Look and Tremble Falls is a shoal or rapids and swimming hole on the Chipola River in the United States state of Florida. It lies south of the County Road 274 crossing of the Chipola (Willis Bridge) west of Altha in Calhoun County. The county's Look and Tremble Park is adjacent to the shoals.
The Chipola River from the Florida Caverns State Park southward is a canoe trail and Look and Tremble is considered a class one rapids (or "a mild class II on its best day"), the lowest in the International Scale of River Difficulty scheme but unusual for the usually flat landscape of Florida. The relative placidity has led Look and Tremble to be called "Glance and Giggle" by local area residents. The area is also popular for tubing and swimming. Holes in the limestone bottom of the river at Look and Tremble are repositories for American Indian artifacts and animal fossils that have washed downstream.
Look and Tremble appears in the title of Look and Tremble: A Novel of West Florida by Jesse Earle Bowden.
