If there’s one thing being stranded on a desert island is good for, it’s getting to know your fellow castaways.

That’s why, for transgender model Carmen Carrera, the nightmarish Fyre Festival in the Bahamas was almost a dream come true. It was a rare moment to show a group of influential strangers who she is as a person — and to confront, head-on, the stigma that still surrounds the lives of transgender people like her.

“It felt like this is the way life should be,” said the activist and model for brands like Steven Meisel, Mark Seliger, and David La Chapelle who was invited to the festival by its organizers.

When Carrera, 32, arrived to Great Exuma island, the scene was indeed a disaster: Her luggage was missing, there were only disaster relief tents for shelter and no food was available for the hordes of hungry visitors. (Lawsuits continue to pile up against the festival’s organizers, Billy McFarland and Ja Rule, about the conditions on the island.)

‘A lot of the time, trans people . . . live in stealth because they don’t want to feel the stigma.’

Though Carrera was invited to attend for free — in exchange for sharing flattering pictures of the festival on social media — she ended up spending more than $1,000 on her own accommodations and for what amounted to be a disorganized disaster.

Amid the pandemonium, Carrera was scared, but for a different reason than other attendees might have been: She wasn’t sure if she should be open about being transgender.

“A lot of the time, trans people face the fear . . . or live in stealth because they don’t want to feel the stigma, or feel alienated or go through any of those traumatic experiences.”

With travel back to Miami restricted, Carrera learned she would be staying the whole week on the island. She decided to look at the bright side: It gave her a chance to chat with models, photographers and high-powered “influencers” about the industry she’s breaking into.

But she did more than whistle in the dark — she turned the chaotic shores of Great Exuma into a platform for her cause.

“I actually shared my story,” Carrera says. “I’m very proud to be transgender . . . I opened up a lot of eyes, and at the same time, I enjoyed myself.”

Carrera advocates for transgender rights off the island, too. As host of the Fusion travel show “Outpost,” she brought awareness to the high murder rate of transgender people in Brazil. She’s also active in the organization History UnErased, which works with educators to include LGBT history in school curricula.

Carrera also recently obtained a new birth certificate reflecting her female gender, and has spoken publicly about the process to raise awareness for transgender rights.

“A lot of these people [at Fyre Festival] have their own businesses, they’re established individuals, many who come from a place of privilege, so they don’t really get to interact with a trans person,” she told The Post. “I finally got to be in a place where I feel like we saw eye-to-eye.”
