One of Arizona's most unique state parks is bringing back a popular event for a second time this weekend.

Tonto Natural Bridge State Park, north of the Payson area, is hosting Brunch at the Bridge this Sunday, April 28, from 10 a.m. to 2 p.m. Participants can enjoy coffee, eggs, bacon and pancakes on the lawn of the park's historic Goodfellow Lodge.

After brunch, a park volunteer will lead a geology walk at 2 p.m. Those who participate will learn more about how the bridge was formed and other interesting facts about the park.

Tonto Natural Bridge formed over the past several thousand years, as calcium carbonate was deposited to create a travertine dam in Pine Creek Canyon. At 183 feet high and 400 feet long, the bridge is believed the largest natural travertine bridge in the world.

Tickets for the event are $15 and are available online or at the park on the day of the event, and include park entry and brunch. Proceeds benefit the Friends of Tonto Natural Bridge State Park.
