The Weirdest Themed Cruises Ever to Set Sail
There’s something about being stuck on a ship in the middle of the ocean that makes people want to commit to a theme. Not just a little — fully, completely, with costumes and matching luggage and a genuine enthusiasm that you’d never expect to find floating somewhere off the coast of the Bahamas.
Themed cruises have been around for decades, but they’ve gotten stranger, more specific, and honestly more wonderful with every passing year. These are the ones that really stick out.
The Heavy Metal Cruise That Refuses to Sink
Imagine waking up to the sound of a guitar solo echoing across the pool deck at 9 a.m. That’s a Tuesday on the 70000 Tons of Metal cruise, which has been running since 2011 and is exactly what it sounds like.
Roughly 3,000 metal fans board a giant ship, and about 60 bands perform over four days at sea. There are no headliners. Nobody is treated as more important than anyone else.
You end up watching your favorite band play in a venue the size of a living room, then running into the guitarist at the buffet line. It’s surreal in the best possible way.
The crowd is surprisingly friendly, the music runs almost around the clock, and the whole thing operates with an organized chaos that somehow works. Metal fans, it turns out, are excellent cruise passengers.
A Voyage for People Who Love Puzzles More Than People
Murder mystery cruises have existed for a while, but the dedicated puzzle and escape room cruises that started popping up in the last decade take things further. Passengers work through multi-day storylines where the whole ship becomes part of the game.
Clues appear in your cabin. Staff members slip into character at breakfast.
The hallways turn into crime scenes. If you’ve ever wanted your vacation to feel like a live-action board game, this is it.
The Star Trek Cruise (Yes, Really)
Starfleet fans have been gathering on cruise ships since 2012. The StarTrek The Cruise experience has featured actual cast members from various series walking the decks, holding Q&A panels, signing autographs, and eating dinner alongside passengers who showed up dressed as Klingons.
There are trivia competitions, costume contests, and enough Trek lore on display to make the uninitiated feel like they’ve accidentally beamed onto a different planet. The thing that makes it genuinely strange — and genuinely great — is the commitment.
People don’t half-heartedly dress up. They go all in, and the cast members seem to actually enjoy it.
Knitting at Sea
There are knitting and fiber arts cruises, and they are probably the most peaceful things on this list. Hundreds of people who share a deep love of yarn board a ship together, spend their days crafting in the sun, attend workshops run by well-known fiber artists, and swap patterns over dinner.
The shops on board reportedly do a brisk business in novelty wool. It sounds niche.
It is a niche. It also has a waiting list.
The Paranormal Cruise
Ghost hunters and believers in the unexplained have their own cruise experience, complete with guest speakers who specialize in the paranormal, séances, discussions of famous hauntings, and late-night investigations of supposedly active areas of the ship. Whether you believe in any of it or not, spending a night doing a ghost investigation in the belly of a cruise ship while the ocean rolls around you is undeniably atmospheric.
Some passengers report experiences they can’t explain. Others report a great nap. Both outcomes seem valid.
Taylor Swift Fan Cruises

Swifties, as any functioning adult already knows, are an exceptionally organized and enthusiastic group. When a Taylor Swift themed cruise sets sail — and they have — passengers show up dressed as different eras of her career, trade friendship bracelets by the thousands, and participate in trivia nights, singalongs, and listening parties that run until the early hours of the morning.
The whole ship becomes a fan convention floating on water. It’s chaotic, loud, and genuinely joyful in a way that’s hard to replicate on dry land.
Bigfoot Believers on the Open Water
The cryptid cruise is real. Fans of unexplained creatures — Bigfoot, the Loch Ness Monster, various sea serpents — gather to hear researchers and enthusiasts talk about evidence, expeditions, and eyewitness accounts.
There are documentaries, panel discussions, and apparently very lively debates about footprint casting techniques. The irony of searching for mysterious creatures while surrounded entirely by the open ocean seems to be part of the appeal.
The Quilt Cruise
Much like knitting at sea, quilt-focused cruises bring together people who are extremely passionate about a specific craft and want to spend a week doing it with other extremely passionate people. Award-winning quilters teach workshops.
Finished pieces get displayed like gallery art. Passengers compare fabric swatches at dinner.
It’s a world unto itself, and it operates with a warmth and camaraderie that most other themed cruises don’t quite match.
Wizard and Fantasy Cosplay at Sea
Fantasy cosplay cruises invite passengers to spend the week dressed as wizards, elves, dragons, and fictional heroes from books, films, and games. The costume quality can be extraordinary — people spend months building their outfits. Group photos on the pool deck look like stills from a movie.
There are tournaments, storytelling sessions, and enough replica swords (blunted, per safety regulations) to stock a small armory. Watching someone in a full dragon costume navigate a buffet line remains one of life’s underrated pleasures.
The Disco Cruise
The ’70s never died on a disco cruise. Passengers dress in platform shoes and wide lapels, the ship’s entertainment consists almost entirely of live funk and soul performances, and the dance floors stay packed until the ship’s staff politely requests everyone go to bed.
There’s something infectious about a few hundred people who have collectively decided that this decade was the best one, and they’re going to prove it at 2 a.m. on the Atlantic Ocean.
Cats. Just Cats.
Cat lovers have organized cruises where the theme is, simply, cats. There are cat-themed art installations, lectures on cat behavior and history, cat video screenings, and an extraordinary amount of cat merchandise.
Actual cats are not typically on board — maritime rules make that tricky — but the devotion is entirely in evidence. Cats are everywhere you look, just not the live version.
The distinction between a cat cruise and a regular cruise, according to people who’ve attended both, is that the cat cruise has better energy.
The Potato Cruise
Norway runs a Potato Festival cruise. That’s the whole pitch.
Passengers travel through the Norwegian fjords while attending events centered on the history, cultivation, and cooking of potatoes. There are potato tastings, potato cooking demonstrations, and enough genuine enthusiasm for the vegetable that it somehow stops feeling absurd after the first hour.
It helps that the fjords are spectacular, though the potato content is reportedly the main draw for regulars.
Teddy Bears and the Open Sea
Stuffed animal voyages started aimed at kids, yet grown-ups now fill cabins too. With plush toys in tow, travelers join games and events shaped around bears, living a week cocooned in cozy, throwback charm.
Gentle rhythms take hold here – nothing rushed – the opposite of typical ship bustle. Calm hums through hallways where laughter lingers like childhood echoes.
A few folks carry around bears passed down through years of family time. Some grab fresh ones at the little store on board, bonding fast without thinking much.
Nobody looks down their nose either way.
The Zombie Apocalypse Cruise
Midway through fake blood and made-up scenes, a boat trip turns into pretend panic when guests act out escaping zombies everywhere onboard. Makeup-covered performers move around while plots unfold on purpose, tasks wait to be finished, plus areas marked safe give short breaks from the noise.
A few travelers stay serious like they live the part. Some laugh their way through each moment instead.
Crew members keep acting no matter how wild things get thrown their direction. Exhaustion hits hard when the days blur into noise.
Chaos sticks, though – loud, constant, impossible to ignore. Folks who’ve lived it won’t forget the mess, the rush, the strange joy tangled up in between.
Somewhere Between Strange and Wonderful
What stands out most about these trips has nothing to do with their odd topics. Instead it hits you when you see how each tiny human obsession finds its way onto a floating event.
One person dreams it up while bobbing across water. Folks arrive by the hundreds – some in alien makeup, others clutching knitting supplies, arguing over what mythical ocean beasts might eat.
People usually don’t meet others obsessed with the exact same odd interest during regular trips. Themed cruises fix that without trying too hard.
Being around folks who light up about the same narrow topic feels different. It does not happen often.
Yet somehow, sailing together makes it real.
