Elevate your experience. Go private — your own boat, your own guide, your own pace. Your Ultimate experience in Hong Kong!

Flexible Tour Start Time

Our join-in tours run on a set schedule — easy, reliable, and ready when you are. But if you're looking for more flexibility, a private tour lets you call the shots.

With a private charter, the departure time is yours to choose. Sleep in and roll up mid-morning. Catch the early golden light for photography. Schedule around nap times, flight arrivals, or a long lazy breakfast. Whatever works for you, we'll be ready — right up to a 2 PM latest departure.

Think of it this way: join-in tours are turn-up-and-go convenience. Private tours are on-your-terms freedom. Both are great ways to experience the Geopark. One just bends around your day, not the other way around.

Private Hong Kong Geopark Sightseeing Experience

On a join-in tour, the route is set and the pace keeps everyone happy. On a private charter, the pace is yours — especially if you're here to photograph.

Want to spend an extra fifteen minutes at Bell Arch, waiting for the perfect cloud to pass? Done. Need the boat to circle back so you can catch the hexagonal columns from a different angle? Just ask. Our captain knows the Geopark inside out — where the light hits best at each time of day, how close to get for dramatic wide-angle shots, and exactly how to position the boat so your frame is clean, balanced, and ready to post.

If you're a drone photographer, a private charter changes everything. You can arrange dedicated flight time, launching from the yacht deck or the speedboat while the captain holds position. Top-down views of sea arches, tracking shots along the volcanic coastline, the hexagonal columns from an angle almost no one gets — all on your schedule, with no rush and no competing for space.

There's no fixed photo window. No one else waiting for their turn. Just you, your gear, and a captain who understands that the difference between a good shot and a great one is sometimes just a few more minutes and a slightly better angle.

Just You and Your People — A Truly Private Escape

Our join-in tours have a brilliant social energy — you meet fellow adventurers, share the excitement, and experience the Geopark together. But if you're looking for something more intimate, a private charter takes that experience and makes it entirely your own.

On a private tour, the only people on board are the ones you invited. Your family. Your closest friends. Your partner. Maybe just you, with a dedicated guide and captain focused entirely on your group. The vibe is whatever you want it to be — relaxed and quiet with chilled music drifting from the speaker, or lively and loud with laughter echoing across the deck. There's no one to disturb and no one to disturb you.

This changes everything about how the day feels. You can have a real conversation without shouting. You can share a quiet moment on the bow without an audience. Kids can be kids without parents worrying they're interrupting anyone else's experience. If someone wants to swim longer, you stay. If the group wants to skip a stop and move on, you go. It's the same stunning Geopark, the same crystal-clear water, the same professional crew — just shaped entirely around you and your people.

Choose Your Route — Go Where You Want

Our join-in tours follow carefully designed routes that showcase the very best of the Geopark — they're popular for good reason. But if you want to take creative control, a private charter lets you co-design the itinerary with your captain.

Want to spend most of your time chasing sea arches and photographing hexagonal columns? The route bends toward geology. More interested in snorkelling in the clearest, quietest bays? We'll prioritise the water over the rocks. Have a specific spot you've seen in photos and desperately want to visit? Let's go there first and linger as long as you like. The captain knows these waters intimately and can suggest hidden gems you might not have considered. Together, you build the day in real time.

This flexibility is especially valuable if you're visiting with a specific purpose. Photographers can plan around the best light. Families can avoid long stretches between stops. Couples can request a quieter beach for a romantic lunch stop. Nothing is locked in. Everything is adjustable. You still get the same expert crew and the same stunning scenery — just on a route that's been shaped around you.

Skip the Queue — Your Time, Your Pace

Skip the Queue — Your Time, Your Pace

One of the biggest advantages of a private charter? You skip the queue. On our join-in tours, we gather all participants at the meeting point, conduct a safety briefing and roll call, then board together as a group. It's efficient, but it does involve a little waiting. With a private charter, the moment your group is assembled and briefed, you step straight onto the boat and go — no waiting for other guests, no idle time at the pier. Your captain and crew are ready for you, and your adventure begins the instant you are. That extra 15 to 30 minutes saved at the start might not sound like much, but it means more time on the water, more flexibility with your route, and a smoother, more relaxed experience from the very first moment.

Perfect for Families, Friends & Special Celebrations

Our join-in tours welcome all kinds of travellers, and we love the mix of people they bring together. But some occasions call for something more personal — and that's where a private charter shines.

Families thrive on private tours. There's room for grandparents to sit in the shade while grandchildren cannonball off the swim platform. Parents can relax knowing the kids are safe, supervised, and free to be themselves. No one feels rushed through a meal or hurried away from a beach. If the toddler needs a nap, there's a quiet cabin. Everyone gets their version of a good time, all on the same boat.

For groups of friends, it's equally effortless. Birthdays on the water — with the Geopark as your backdrop and zero stress about logistics. Proposals on a hidden beach at golden hour, with no strangers in the background of your photos. Anniversaries spent snorkelling side by side, followed by fresh fruit on deck as the sun drops toward the horizon. Whatever the occasion, a private tour turns it from a plan into a memory. You just bring your people. We'll handle everything else.

Birthdays, Proposals, Anniversaries — Make It Unforgettable

Our join-in tours create brilliant shared memories — strangers becoming friends, everyone swapping photos at the end of the day. But some moments deserve a stage of their own. A private charter gives you exactly that.

Imagine celebrating a birthday not in a crowded restaurant, but on a yacht drifting past volcanic sea arches, the sun warming the deck, your favourite music playing, a cold drink in hand, and everyone you love around you. No fixed seating plan. No time limit on your table. Just the open sea and a day that unfolds exactly how you want it.

Planning a proposal? Picture this: a hidden beach at golden hour, accessible only by boat, with no strangers in the background of your photos and no one photobombing the most important question of your life. The captain knows the quietest coves, the most beautiful backdrops, and exactly when the light will be perfect. You focus on the moment. We'll handle the timing.

Anniversaries deserve more than dinner and flowers. Spend the day snorkelling side by side above coral reefs, floating in a natural infinity pool, watching the sunset from the deck with fresh fruit and salt-tinged skin. No crowds. No rush. Just you and your person, on a boat, in one of the most spectacular corners of Hong Kong.

A private tour doesn't just host your celebration — it becomes part of it.

Ask All the Questions You Want — Undivided Attention

On our join-in tours, our guides do a fantastic job looking after the whole group — keeping everyone safe, on schedule, and engaged. But if you're the kind of traveller who wants to go deeper, a private tour gives you something extra: a guide who's focused entirely on your group, for the whole trip.

If you're genuinely curious about the geology — why the columns are hexagonal, how the supervolcano collapsed, what forces carved the sea arches — you can ask. And keep asking. The conversation can go as deep as you like. Your guide isn't delivering a rehearsed script. They're responding to your questions, your interests, your pace. Want to know more about the marine life? They'll focus on that. Fascinated by the rock formations? They'll geek out with you for as long as you like.

It's not just about learning, either. Kids get patient, gentle instruction during snorkelling. Nervous swimmers get extra reassurance. Photographers get positioning tips. Your guide notices if someone looks tired and suggests a break before you even have to ask. Everyone gets the version of the experience they need, because the guide only has one job: taking care of you.
