The towns of Oro Valley and Marana are cooking up fun for folks from near and far on July 4.

While Tucson's "A" Mountain fireworks get a lot of notice, festivities on the northwest side are nothing to sneeze at. Fourth of July activities draw people from all over the area, so be prepared for crowds.

In Oro Valley, events start at 3 p.m. and lead up to a 9 p.m. fireworks display sponsored by the Hilton Tucson El Conquistador Golf and Tennis Resort.

The action will include live music - including Little House of Funk and the Bryan Dean Trio - food trucks, arts and crafts and a jumping castle, all at James D. Kriegh Park, 23 W. Calle Concordia.

The Oro Valley Aquatic Center, which is in the park, is offering discounted admission of $2 for adults and $1 for children. The center will hold contests and games.

Marana's Arizona Pavilions district, near Interstate 10 and Cortaro Road, will be a busy place, too, starting with a movie at 6 p.m. at Crossroads at Silverbell Park, 7548 N. Silverbell Road, followed by fireworks at 9, weather permitting

There won't be any food vendors, so bring a picnic or edibles from any of the many nearby restaurants, along with a blanket or chairs.

Driving tip: Use the eastbound I-10 frontage road to Burlingame Road to access businesses on the south side of Cortaro Road.
