Skip the Heat. Discover the Ultimate Thing to Do in Hong Kong This Summer.
Let me paint you a picture.
It's a scorching Saturday in July. Hong Kong's summer is in full force — 33°C, humidity so thick it wraps around you the moment you step outside, the sun a relentless white glare that makes the pavement shimmer. By 10am, just walking from the MTR to the street has you breaking a sweat. By noon, you're exhausted just from existing. You've been searching "things to do in Hong Kong summer" for weeks, scrolling endlessly through lists of air-conditioned malls, indoor playrooms, overpacked public pools, and beaches so crowded you can barely find a patch of sand to put your towel down. Everything feels like a compromise. Everything feels like surviving the heat rather than actually enjoying summer.
But here's the thing: Hong Kong's summer isn't meant to be survived indoors. It's meant to be embraced — out there, on the water, where the heat becomes your friend instead of your enemy. Where the only thing between you and the sun is a cool sea breeze. Where the moment you get too warm, you just jump in.
My Day on Splitdyboat's Yacht Snorkelling Tour
Imagine this instead.
You meet at Sai Kung Public School near Sai Kung Public Pier in Sai Kung Town Centre of Hong Kong. It's mid-morning — the sun is up but not yet punishing. After the gear check session, you step onto a yacht. Not a packed ferry, a yacht with space to stretch out, a roof for shade, sea breeze on your face, and the quiet hum of a Bluetooth speaker playing summer tunes. The crew unties the ropes and you pull away from the pier. The harbour opens up ahead of you. The water turns from murky green to deep blue. The city feels a long way away.
10:00 AM – Sai Kung Public School: The Adventure Begins
I arrived at Sai Kung Public School and was greeted by the Splitdyboat team. They were organized, friendly, and immediately put me at ease. Within minutes, I was stepping onto a spacious, comfortable yacht. The city noise faded as we pulled away from the pier, heading out toward the open sea.
The boat glided past the dramatic coastline, and our guide started pointing out the geological wonders. I wasn't expecting a geology lesson, but watching the towering hexagonal rock columns of the UNESCO Global Geopark slide by was genuinely breathtaking. These were 140-million-year-old volcanic formations, right on Hong Kong's doorstep.
11:00 AM – Bell Arch in Jin Island (Four Largest Sea Arches in East Seas)
You're heading into the Hong Kong UNESCO Global Geopark — a coastline of staggering natural beauty just 30 minutes from Sai Kung. One hundred and forty million years of volcanic history exposed in hexagonal rock columns stretching for kilometres. Giant sea arches carved by wind and waves, so big that a speedboat can even pass through them. Uninhabited islands with white sand beaches and water so clear you can see the coral from the deck of the boat. This isn't Thailand. This is Hong Kong. And almost nobody knows it exists.
This is the Splitdyboat Yacht Beach Snorkelling Tour — a full-day, 6-hour experience that completely redefines what "things to do in Hong Kong summer" actually means.
11:30 AM – Glass Water and Hidden Coral
We anchored near Kau Sai Wan Beach, a secluded spot that feels a world away from the city. The water was so clear it looked like glass – a pale, turquoise green that invited you to jump in.
After a short speedboat transfer to the beach, we put on our snorkelling gear. Now, I've snorkeled in Thailand and the Philippines, so I was curious – how would Hong Kong compare? The answer surprised me. Within seconds of putting my face in the water, I was surrounded by colorful coral and schools of tropical fish. The coral cover here is said to be around 80%, and it showed. It was vibrant, alive, and teeming with life.
The instructor stayed close, pointing out different species and ensuring everyone was safe and comfortable. For beginners, it was reassuring. For me, it was an unexpected highlight – a reminder that Hong Kong's natural beauty is often overlooked.
The yacht takes you to places no road can reach. You'll snorkel in bays where visibility hits ten metres in summer, floating above coral communities and chance watching clownfish — actual Nemos — dart in and out of sea anemones right beneath you. You'll swim at hidden beaches accessible only by boat, with no crowds, no entrance fees, no fighting for space. You'll cruise past giant sea arches, camera in hand, trying to capture a view that looks too dramatic to be real. You'll watch your kids shriek with laughter as they zoom down the yacht's inflatable water slide, then float on mats with the sun on their faces. You'll eat lunch served right on the yacht or on the beach because nothing works up an appetite like in a summer spent swimming in the sea.
12:30 PM – Seasonal Seaside Waterfalls & Infinity Pool
The Seasonal Seaside Waterfalls – A World-Class Hidden Gem
The Seasonal Seaside Waterfalls are a world-class hidden gem where fresh water meets the sea in a striking natural setting. Best seen after rainfall, the falls cascade beside rugged cliffs, creating a rare and refreshing contrast of rock, water, and ocean. Their secluded location adds to the sense of discovery, making every visit feel like an adventure. It is a peaceful, scenic spot that rewards curious travelers. Absolutely the best scene to see in Hong Kong summer. Then what is the best things to do in Hong Kong summer? you are being inside and enjoy it.
The Seasonal Infinity Pool – A Hidden Gem
After snorkelling, our guide led us to a spot behind the beach – a natural rock pool formed by the tides. When conditions are right, it looks like an infinity pool, with the sea stretching out beyond the rock ledge. It was quiet, magical, and a perfect photo spot. This was the kind of hidden gem you just can't find in a theme park.
01:30PM Lunch on the Yacht – Eating with a View
By 1:30 PM, we were back on the yacht and lunch was served. There's something special about eating a hot meal with the sea breeze in your face and nothing but blue water in every direction. The food was simple but satisfying – rice, meat, vegetables – and the relaxed atmosphere made it feel like a private sailing trip, not a tourist excursion.
Water Toys and Laughter
After lunch, the yacht's toys came out. There was a huge inflatable slide that had everyone – adults included – laughing and screaming as they splashed into the sea. Some tried stand-up paddleboarding, while others floated on giant inflatable rafts.
I spent a good hour just floating in the water, bobbing on a giant mat, watching the sky and feeling the sun on my face. No queues. No pushing. No crowds.
If you’re looking for the best thing to do in Hong Kong summer, this yacht escape is hard to beat. It combines sea breeze, water play, and pure relaxation in one unforgettable day, making it a perfect choice for families, friends, and anyone who wants to enjoy Hong Kong’s sunshine away from the city crowds.
The Golden Hour Return
As we started heading back to Sai Kung, the sky turned golden. The sun hung low, casting long shadows across the water and painting the islands in soft, warm light. This was the magic hour, and the view was stunning. I spent the last part of the journey on the upper deck, camera in hand, capturing the sunset. It was the perfect ending to a perfect day.
What I Loved Most
Reflecting on the day, a few things really stood out.
Space and Freedom
There were no crowds. The yacht wasn't packed. I could move around freely, find a quiet corner to relax, and truly disconnect. After weeks of busy city life, this felt like a real getaway.
Connection with Nature
I wasn't just being entertained – I was experiencing something real. The corals, the fish, the rocks, the clear water. It all felt untouched and authentic.
Everything Was Sorted
I didn't have to think about anything. The gear was provided, the lunch was ready, the guides were professional. All I had to do was show up and enjoy.
Photos You Can't Get Anywhere Else
Water World photos are mostly water slides and crowds. My photos from this trip looked like they were taken in Okinawa or Thailand – glassy water, vibrant coral, and epic landscapes. The likes poured in.
Would I Choose It as the Best Thing to Do in Hong Kong Summer?
And here's what you'll notice: you're not checking the time. You're not counting how many things you've done. You're not rushing anywhere. You're just... there. Floating. Happy. Cool whenever you want to be — just jump in. Warm whenever you want to be — just climb back on deck. The heat that felt oppressive in the city now just feels like summer. Real summer. The kind of summer you remember from childhood, when the days felt endless and the water was always calling.
That's the difference. Hong Kong's summer heat isn't the problem. The problem is spending it in the wrong places.
Lunch is included. Fresh fruit is served before you head back. The crew takes care of everything. All you have to do is show up, bring sunscreen and a towel, and be ready for the best summer day you've had in years. Kids under 4 go free.
This summer, don't just survive the heat. Use it. Let it be the reason you finally get on a boat and discover the Hong Kong that exists beyond the shoreline — the one with 260 islands, world-record geology, hidden beaches, and water so clear you'll forget you're half an hour from Central.
The Geopark has been here for 140 million years. It's not going anywhere.
But summer is short. And your spot on the yacht isn't going to book itself.
Book your Splitdyboat Hong Kong Yacht Beach Snorkelling Tour and discover a summer experience you won't find at any theme park. The real Hong Kong summer is waiting — out there, on the water, where the heat finally makes sense.
