From hidden underground passages and secret woodland cafés to discreet bars, peculiar museums, rooftop campsites, service robots, ghost stories, and famous farm animals, Cape Town has plenty of wonderfully unconventional experiences waiting to be discovered.
When people search for things to do in Cape Town, they are often shown the same famous sights again and again. You probably already know the ones I mean—the attractions that instantly come to mind whenever someone mentions the city. They are popular for good reason, but they are not the whole story.
After living in Cape Town since 2020, I have spent plenty of time exploring beyond the usual visitor checklist. Along the way, I have found a collection of unusual places, odd little adventures, and memorable experiences in and around the city that deserve more attention.
This is not another generic roundup packed with predictable recommendations or questionable suggestions copied from elsewhere. It is a guide to the stranger side of Cape Town: places where you can chat to a hotel robot, descend beneath the streets into historic tunnels, and encounter the legacy of a world-famous painting pig.
Below, you will find a handpicked list of alternative attractions, offbeat outings, and unique adventures to add to your Cape Town plans.
Unusual Things to Do in Cape Town: Tunnels, Ghosts, Pirates and More
Cape Town is full of famous sights, but beyond the postcard views lies a stranger, more playful side of the city. From hidden waterways and wartime bunkers to rooftop trailers, robot hosts and pirate cruises, these experiences offer a memorable way to see the Mother City differently.
Explore the Castle’s hidden tunnels
The Castle of Good Hope is South Africa’s oldest surviving building and one of the world’s finest remaining Dutch East India Company forts. A visit is essential for anyone interested in the country’s colonial past, but the Castle and Dungeon Tour with Good Hope Adventures goes a step further—literally.
The tour leads below the fort into Cape Town’s largely forgotten underground passages. Some of these routes can be traced back to 1652, when the Dutch began shaping streams flowing from Table Mountain into formal canals, known as grachte.
Their dream of creating a miniature Amsterdam at the Cape never fully materialised. As the canals became dirty and unhealthy, they were closed off and converted into underground channels. Many locals have no idea that this hidden network still exists beneath the city.
Bring a headlamp, wear shoes you do not mind getting muddy, and prepare for darkness, giant cockroaches and perhaps a ghost story or two.
Lose your bearings at the Museum of Illusions
For a more light-hearted indoor adventure, the Museum of Illusions offers around 60 hands-on installations designed to challenge what you think you are seeing. It is a great option for families, friends, and anyone wanting eye-catching photographs.
Expect distorted mirrors, a spinning tunnel that makes the floor feel unstable, and Cape Town-inspired displays such as an upside-down Bo-Kaap room. It is a short escape from reality without ever leaving the city centre.
Sleep in a rooftop Airstream trailer
The Grand Daddy Hotel has transformed its roof into something wonderfully unexpected: a designer Airstream Trailer Park. Seven vintage-style trailers sit above the city, each decorated around its own South African road-trip theme.
Staying there is certainly not the cheapest way to spend a night in Cape Town, but it makes for a genuinely unusual hotel experience. If a trailer stay is beyond the budget, head up to the Sky Bar for a drink instead. You can enjoy the rooftop atmosphere, admire the trailers and take in the city views without booking a room.
Meet the robots at Hotel Sky
Hotel Sky feels as though it belongs in a futuristic film. Its striking modern exterior, distinctive rooftop lights and robot concierges set it apart from most hotels in the city.
The robotic hosts—Mika, Skyla and Maya—can offer information about the hotel and Cape Town, with varying degrees of success. When the hotel opened in 2021, seeing robots greet guests was still a novelty. Today, it remains an entertaining stop even for visitors who are not staying overnight.
For a more dramatic experience, make your way up to the rooftop Sky-Hi ride. The vertical drop attraction lifts riders high above the city before delivering a sudden plunge, paired with spectacular views of Table Mountain and the skyline.
Take a ghost walk through Simon’s Town
Simon’s Town has naval history, old buildings and plenty of stories that lend themselves perfectly to a ghost tour. The Simon’s Town Ghostwalk, led by Andre, mixes local history with unsettling tales and folklore.
Along the route, you may hear about heritage sites, hidden tunnels, old cannons and a mass grave uncovered during construction. There are also stories about colourful historical characters, including explorer and Anglo-Boer War nurse Lady Mary Kingsley.
Places such as Admiralty House and the British Hotel are said to have paranormal connections. Whether or not you encounter anything supernatural, the walk is an atmospheric introduction to one of the Cape’s most historic coastal towns.
Crack the code to enter a secret bar
The Art of Duplicity is Cape Town’s take on a Prohibition-era speakeasy. Hidden in an unmarked city-centre alley, it is not a place you simply stumble into. Visitors need to follow clues, find the entrance and work out the password before being allowed inside.
Once through the door, the mood shifts to the 1920s. Vintage décor, classic-inspired cocktails and occasional live jazz create the feeling of stepping into another era. The hunt is part of the fun, but the reward is a stylish and memorable night out.
Visit a tiny fairytale in Constantia
Little Stream in Constantia has an enchanting quality that is difficult to explain. The grounds feature a tree swing, whimsical sculptures, oversized figures in the greenery and ruins that look as though they might have been borrowed from a fantasy novel.
It is a lovely spot for children, but adults who appreciate a little magic will enjoy it too. There is also a peaceful tea garden where visitors can sit beneath the trees for tea, cake or a meal. Even the cheesecake feels as though it belongs in a storybook.
Enter a World War II bunker
Tucked into the Twelve Apostles area, the TOP SECRET Tunnel and Bunker Tour takes visitors into a former World War II military site. The experience includes enormous guns, ammunition rooms, radar stations and long underground passages.
A former Navy veteran guides the tour, sharing stories about Cape Town’s wartime role. The tunnels are narrow, dark and winding, adding a welcome dose of tension to the history lesson. The experience finishes with a theatrical interrogation-style challenge, making it as playful as it is educational.
Become a pirate for the day
The Jolly Roger Pirate Boat at the V&A Waterfront is ideal for families, birthday celebrations or adults embracing their inner pirate. South Africa may not have a famous pirate legacy of its own, but that does not stop this ship from delivering a cheerful swashbuckling adventure.
The company offers short cruises as well as longer sunset outings. The boat’s sails, lively atmosphere and views of Table Mountain make it a fun way to get onto the water. If conditions are right, you may even spot whales.
Pack an eye patch if you like, but leave the questionable pirate behaviour behind—this is a family-friendly voyage.
Drink coffee in a steampunk world
Truth Coffee is much more than a café. Its dramatic steampunk interior is filled with industrial pipes, metalwork, gears, Victorian-inspired machinery and staff dressed to match the theatrical setting.
The large cast-iron coffee roaster is not just decoration: coffee is roasted on site. Despite the imaginative design, the quality of the coffee is taken seriously, and the café has received international recognition.
Whether you come for a tasting, a meal, a pastry or simply a strong cup of coffee, Truth Coffee is an experience for both your camera and your caffeine habit.
Ride the amphibious Waterfront Duck
The Waterfront Duck Co. offers one of the city’s most unusual sightseeing trips: a tour in a 36-seat vehicle that travels on land and water. It begins as a city tour before the bus-boat splashes into the V&A Waterfront marina.
The guides, known as “Con-duck-tors,” add jokes and commentary along the way. It is a light, entertaining choice for visitors who want a classic sightseeing tour with an unexpected twist.
Wander through an abandoned zoo
Cape Town’s former Groote Schuur Zoo is a fascinating destination for people drawn to forgotten places. Located on the University of Cape Town grounds, the abandoned site is filled with overgrown paths, rusting cages and crumbling animal enclosures.
The zoo closed sometime between the mid-1970s and mid-1980s, and nature has steadily reclaimed the area since then. It is a haunting, unusual place to explore—proof that even a city as busy as Cape Town has hidden corners where time seems to have stopped.
Cook, dance and socialise at Food Jams
Food Jams turns a cooking class into a party. Hosted in a lively Salt River studio, the experience includes welcome drinks, snacks, music from a live DJ and plenty of opportunities to meet new people.
Participants prepare food together, often with a local twist—think dishes such as ostrich bobotie—and the emphasis is on fun rather than perfection. There is no intimidating chef energy here; just cooking, conversation and the occasional chance to use a blowtorch.
Hunt for oddities in Kalk Bay
Kalk Bay is one of the best places in Cape Town to browse for antiques, but do not expect only polished silverware and traditional furniture. This neighbourhood has a taste for the strange, charming and wonderfully random.
You may find something genuinely valuable, but you are just as likely to find an item that makes you ask, “Who owned this, and why?” The mood is closer to a fictional treasure-filled antique shop than a formal showroom.
Do not miss Whatnot & China Town, a shop packed from floor to ceiling with crockery, porcelain ornaments, tea sets and delightfully eccentric finds. Just try not to sneeze while you are inside.
Paddle through the Waterfront at night
Night kayaking at the V&A Waterfront gives the marina a completely different atmosphere. As the light fades, the surrounding buildings and waterfront homes begin to sparkle, their reflections turning the canal into a field of moving lights.
The outing offers gentle exercise, entertaining guide commentary and plenty of photo-worthy moments. With safety equipment and LED lighting provided, it is a calm but distinctive way to experience Cape Town after dark.
