Three things to do this weekend

Saturday and Sunday: Join a free, guided hike at the Nisqually National Wildlife Refuge. “The Wonder of Nisqually” – an exploration of the plants and animals on the refuge – leaves the Visitor Center flag pole at 10 a.m. Saturday and 1 p.m. Sunday.

All weekend: The Johnston Ridge Observatory at Mount St. Helens National Volcanic Monument is open each day from 10 a.m. to 6 p.m. The observatory gives visitors an up-close look at the Mount St. Helens crater. A pass to all Mount St. Helens National Volcanic Monument visitor areas is $8 a day. Visitors 15 and younger get free admission. For more information, visit www.fs.fed.us/gpnf.

All weekend: Panfish – bluegill, crappie, yellow perch and rock bass – are biting in most South Sound lakes. These fish are in shallow water and are easy to catch with a worm dangling below a bobber.

National Trails Day

June 6 is National Trails Day, and the Washington Trails Association has lots of volunteer work parties scheduled for spots throughout the state, including Mount Rainier National Park, Olympic National Forest and in the North Bend area. Most work parties start in the morning meeting spot and then end with a late-afternoon picnic.

The Glacier Basin Trail in Mount Rainier National Park and the South Fork Skokomish Trail in Olympic National Forest are just two of the many trails slated for work parties. For more information – or to sign up for a work party – visit www.wta.org.
