More than 70 floats and entertainers will descend Main Street and City Park will be buzzing with activities including a 5K run, live entertainment, races for children, rugby and barbecues.
Pulling it all together is something the nonprofit organization called the Park City Ambassadors takes pride in.
"It's exciting and fun to see all the people, especially the children who haven't been in the parade get a chance to be in the lineup," said Joel Fine, a Park City Ambassador. "It's also great to see everyone having a great time."
This year, Park City expects more than 20,000 to participate in the celebration that starts in City Park with a Boy Scout pancake breakfast.
"We are asking everyone to please take the bus, ride their bikes or walk," Fine said. "Please, plan accordingly, because it's going to be jammed up here."
The Cole Sport 5K will begin at 8 p.m. Runners who are interested in participating can register by visiting www.colesport.com or calling 435-649-4806.
"City Park will become a promenade on this day, so there will be minimal vehicle traffic allowed," Fine said. "We want people to remember that because safety is a big concern."
The highlight of the day will be the parade that begins at 11 a.m. This year, there will be approximately 70 entries that will strut their stuff down Main Street.
"We've got some interesting entries this year," Fine said.
The theme this year is Hats Off to America.
"It's a good theme and hopefully we'll have some great entries," Fine explained. "Unfortunately, as in the past couple of years, we won't have an Air Force fly over. But we will have some vintage biplanes that will fly over around the start of the parade."
There will be some other interesting sights on the parade route as well, he said.
"When I say interesting, I mean that some of these are new entrants," Fine explained. "There have been people who have been in the parade for a number of years, so it's nice to get some new ones as well.
"We have some great entertainment as well that will be part of the parade," Fine said.
These artists include the Mariachi Zavala, the Salt City Saints, the Park City High School Marching Band, the Ben Lomond High School Pipe Band from Ogden and the Kearn's High School Cheerleaders.
"We try to make sure things are fresh every year," he said. "We do have some of the old standbys but it's nice to get different things."
Spectators will see a number of horses, a couple of mules and a goat in this year's parade.
"The goat will be a first for us," Fine said with a laugh.
Following the parade, the throng is invited to walk to City Park for some more activities that will include live music by Swagger, Cody Jordan and a newcomer, the Austin Wolfe Band to name a few.
"Austin lives in Park City and was one of the contestants on 'American Idol' last season," Fine said. "So we're really pleased about having her perform."
Lunch will be sold by the Sunrise Rotary, and the Park City Ambassadors will also sell pizza, beer and Coke.
"We also are going to provide kids games and at the north end of the playing field, which is new for us this year," Fine said. "We're trying to get more kids and families involved."
Fine praised his fellow Park City Ambassador, David Goldberg, for heading up the City Park activities.
"David does one heck of a job doing that," Fine said. "He's the guy who makes sure it's set up the way it's supposed to be and makes sure the bands and the vendors are in and out when they need to be."
The one thing the Park City Ambassadors would appreciate are more volunteers for crowd control and parade pacers.
"We would sure like to have people help us for a couple of hours or more," Fine said.
Anyone who wants to be a volunteer can call Fine at 435-901-2171 or email him at email@example.com
They can also call Kandi Kutkas at 801-472-2675 or email her at firstname.lastname@example.org .
"We'll take volunteers up until the last second," Fine said. "They can also show up at 7 a.m. at one of our tents at City Park."
Volunteers will get a free T-shirt and water for their help.
"They should come properly dressed in shorts, a hat and have some sunscreen and water," Fine said. "One of the interesting things about our volunteers is that in the past, we've had visitors who are here for vacation become volunteers. They see what's been going on and come down to get involved."
Fine is looking forward to the event and hope everyone has fun.
"Again, we really want to stress the safety aspect of the day," he said. "People need to know where they are and where their children are."
Park City's annual Fourth of July Celebration will be held Friday. (See accompanying schedule titled "Park City's Fourth of July schedule").
