Led by the museum’s educators, attendees will explore the shore, learn about local shells and mollusks, and see the sunrise while avoiding the afternoon heat and humidity of the wet season. The cost is $15 for adults and $5 for museum members and ages 17 and under. The deadline to purchase tickets is July 22 at 11:59 p.m. For tickets or more information, visit ShellMuseum.org/beach-walks. To reach BAILEY-MATTHEWS NATIONAL SHELL MUSEUM & AQUARIUM, please email
