Turtle Bay Exploration Park, Science museum and zoo in Redding, United States.

Turtle Bay Exploration Park is a science museum and zoo in Redding, California, set along the Sacramento River with indoor exhibits on regional wildlife and natural history. The grounds also include outdoor gardens and an arboretum, connected by walking paths and a footbridge over the river.

The park took shape in the mid-1980s, when three Redding museums began negotiating to build a museum complex on 60 acres; plans developed through the mid-1990s. The McConnell Arboretum & Botanical Gardens opened on May 30, 2005, with 20 acres of gardens and 200 acres of arboretum. The park is now restoring 340 more acres of riparian habitat on both banks of the Sacramento River.

The Turtle Bay Museum holds a full-size reconstruction of a Wintu bark shelter, built to show how the Wintu people of the Sacramento Valley lived. Exhibits also cover the area's cultural history alongside its natural history, art and science, and the park runs educational programs about the Wintu.

The grounds are easy to walk and clearly marked, so starting from the main entrance gives you a natural route through the different areas. Allow at least half a day if you want to see both the indoor exhibits and the outdoor sections at an easy pace.

The Sundial Bridge, designed by Santiago Calatrava, is 700 feet long and 23 feet wide, and its pylon works as a working sundial. The bridge carries the Sacramento River Trail, and the McConnell Arboretum opened across the river on May 30, 2005.
