Know Before You Go
On an attempted visit at 5 p.m. on May 19, 2017 on foot through the main entrance I was asked to leave by a security guard. The stadium is also protected by a 6ft chainlink fence. I was also told that "no photography is allowed even from a distance." You can still get a good look at the building by hanging out on the nearby boat dock and beach. Although not advisable, illegally trespassing would best be done by sneaking in through the left side of the stadium (when facing the water) where, in the low tide, there is no fence protecting an entry way. Also reaching that access point is best done by walking to the stadium via the shoreline (with downtown Miami to your back) rather than the main entrance as this is where a security guard is generally hanging out with nothing better to do but tell artists and urban explorers to get lost. You can also get a good legal look at the inside of the stadium by taking a boat out in front of it. Consider an Atlas Obscura two-fer with this site and the Vizcaya Museum and Gardens, less then seven minutes away.
