Washington state turns 125 on Tuesday. Here are three ways to celebrate.

Washington 125 Commemoration

A free, public party Tuesday on the grounds of the Capitol in Olympia (pictured) will feature marching bands, mariachi and gospel music, tribal blessings, dancing (Massive Monkees!), exhibits and a re-creation of the telegram delivery that announced Washington’s statehood at 3:09 p.m. on Nov. 11, 1889. Not to be overlooked: cake. The celebration gets under way at 1 p.m. Nov. 11, Legislative Building, Capitol Campus, Olympia (washingtonhistory.org).

Great Hall of Washington History

Brush up on state facts and historical figures at the Washington State History Museum in Tacoma. Walk through the Great Hall to view a chronology of the region, from the geologic past through early native civilizations to statehood and beyond. 1911 Pacific Ave., Tacoma; $8-$11 (253-272-9747 or washingtonhistory.org).

Lewis & Clark Interpretive Center

Visit the area where explorers Meriwether Lewis and William Clark reached the Pacific Ocean in 1805, opening up the Northwest — for better and worse — to settlement. In the center you’ll find exhibits, murals, films and a glassed-in observation deck with views of the pounding Pacific 200 feet below. Wednesdays-Sundays in winter, Cape Disappointment State Park, Ilwaco, Pacific County; $2.50-$5 (360-642-3029 or parks.wa.gov/187/Lewis-Clark-Interpretive-Center).
