Street art has become an intrinsic part of the cultural fabric of our modern cities. Through the new book “Street Art” (Lonely Planet, $19.99), curious travelers and budding artists learn about the secret stashes of murals and other art as well as vibrant festivals underway in more than 140 cities around the world. Here are four in the United States.

1 LOS ANGELES

Within 50 or so walkable blocks of the Arts District, just east of downtown, you’ll find galleries amid warehouses and former factories sporting public art. In Venice Beach, the people are as colorful as the artwork. On and near Market Street, look for the Om sign, the Pink Panther and a bulldog chasing butterflies. Don’t miss the muraled buildings along the boardwalk and the Public Art Wall at the beach.

2 CHICAGO

The Wabash Arts Corridor is helping to revitalize parts of the city by creating an ever-changing artistic landscape. Look for several large-scale murals that have emerged along a mile-long strip of Wabash Avenue. Expect vivid eyeballs, superheroes and harmony messages. The 606 Trail, an elevated hiking and biking trail along a repurposed train track, provides the opportunity to view murals painted by community groups.

The Murals in the Market nine-day festival celebrates the role of street art by inviting local and international artists to paint large-scale murals each year. The series of events includes discussion groups, cultural and bike tours and additional art exhibits. Street art has been an important part of Detroit’s recent revival. For example, the Grand River Creative Corridor features nearly 100 murals and a fine arts outdoor gallery.

4 HONOLULU

The annual POW! WOW! Hawaii festival brings together more than 100 local and international artists each year to create murals and installations in public spaces. The concept pays homage to the American Indian powwow, a gathering that celebrates culture, art, music and community. Since its origin in Hawaii, the organization has expanded to other cities around the globe.
