Tacoma Nature Center and and Point Defiance Zoo & Aquarium has two summer programs aimed at helping children and adults learn more about Puget Sound’s beaches and the creatures that live there.

The Nature Center will host the second of its 2012 “Tiptoe through the Tidepools” on July 3 from 10 to 1 p.m. at Titlow Beach, 8425 Sixth Ave. The zoo’s “Explore the Shore” programs are set for varying times on June 21, July 2, July 31 and Aug. 29 at Owen Beach in Point Defiance Park.

All are timed to take best advantage of the low minus tides that reveal many of Puget Sound’s most interesting shoreline creatures.

The events and programs are free and open to the public and reservations are not required. Bring sunscreen and wear shoes and clothing appropriate for walking on rough beach terrain.

All programs have meet-up times so participants can get a brief introduction to the day before the walk begins. They’re designed to last about two hours, though people may want to explore the beach for a longer time.
