The Packery Channel Jetties are a series of rock formations located at the entrance of Packery Channel. They provide protection to the channel and create a natural habitat for various marine species. The jetties are a popular spot for fishing, as they attract a wide range of fish including redfish, speckled trout, and flounder. Visitors can cast their lines from the rocks or simply enjoy the view of the crashing waves. The Packery Channel Jetties offer a unique fishing experience in the midst of the park's natural beauty.
