Despite a brief rain shower, around 400,000 fans packed Miami's streets to celebrate the Heat's second straight championship.
Fans cheered as double-decker buses and semi-trucks carrying Heat players, team executives and their families rolled slowly down Eighth Street and onto Biscayne Boulevard.
During the parade, Game 6 hero Ray Allen sprayed fans with a Super Soaker, Chris Bosh clutched the Larry O'Brien trophy while LeBron James chewed on a cigar.
"It's the ultimate," Finals MVP LeBron James said. "This is why I came down here, to have a parade at the end of the year."
Down 3-2 to the San Antonio Spurs, the Heat took the last two games in Miami to win a second straight title and their third overall.
The parade then went straight to AmericanAirlines Arena, where the team celebrated with season ticket holders.
During the celebration inside the Triple A, Miami Mayor Tomas Regalado declared that the Heat would capture a third straight championship next season.
"Next year," Regalado said. "Repeat! Repeat!"
According to Miami police spokeswoman Kenia Reyes, the parade created a huge highway traffic jam while intersections in downtown Miami were closed for the parade.
"There's so many people here it's incredible," said Reyes. "A lot of people want to make it downtown and they've got to remember there's a big parade route."
Some fans, including Carlos Hernandez, from Coral Gables, beat the traffic by riding the Metrorail.
Hernandez said he woke his family before dawn to make it to downtown on time. He said they caught the Metrorail from the Douglas Road station, but had to deal with delays.
"It definitely beats driving all the way down, looking and paying a crazy number for parking and then getting out of insane traffic," Hernandez said. "But man, these delays are killing me."
