Big Wave Bay, otherwise known as Tai Long Wan (Sai Wan) might just be the best beach in Hong Kong. Put the effort in to get there and you'll be treated to a Hidden Lagoon, cliff Jumping, surf, and pristine sand. If you’re craving an escape that’s part adventure, part paradise—Tai Long Wan (Sai Wan) in Sai Kung hits the sweet spot. With a scenic mountain trail, powdery white sand, and even a hidden lagoon pool, it’s one of the most rewarding day trips you can do around Hong Kong. And yes, there’s even a cliff-jumping spot for the bold. The hike: scenic and snappy There are two options to get to Sai Wan on foot. For the shorter option, you’ll need to hike around 30 to 45 minutes through the gorgeous Sai Kung countryside from Sai Wan Pavilion. The trail winds through lush hills with panoramic sea views, and it’s gentle enough that even casual hikers will enjoy it. Bring water, a camera, and maybe a towel: you’ll warm up just enough to want to jump straight into the sea. The other route is a longer hike, but it's easier to get to the start point by public transport. Take the bus to Pak Tam Au and head along section 2 of the Maclehose Trail. The walk is about 6.5km, it's all paved, but there are some steep hills. Getting there via Sai Wan Pavilion From Sai Kung town, a taxi to the start of the trail takes around 10–15 minutes and costs about HKD 150–200 (shared among four, it’s super reasonable). There’s also a public transport option via minibus if you’re budget-conscious (more info below). Minibus: Route NR29: Sai Kung Town Hall - Sai Wan village (Sai Kung) Pick Up: 16 Chow Man Street Drop off: Sai Kung Sai Wan Road (Near sai wan pavilion) Departure times: Monday - friday (except public holidays) 8.30 a.m. 9.15 a.m. 11.30 a.m. 3.30 p.m. Saturdays, Sundays and public holidays 8.30 a.m. 9.30 a.m. 10.00 a.m. 11.00 a.m. 11.30 a.m. 3.30 p.m. 4.15 p.m. 4.45 p.m. Getting there via Pak Tam Au From Sai Kung Bus Terminus take the 94 bus (departs roughly every half-hour), or from Sai Kung Pier Minibus Terminus, take the number 7 (towards Hoi Ha). Get off at Pak Tam Au, where you'll find a public toilet with a drinking water refill station and vending machines selling cold drinks. Head past the toilets and along Maclehose Trail section 2. This route takes you along the coast, through some almost abandoned villages, before crossing the hills and dropping down towards the beach. The trail is paved, but there are steep sections. The beach: quiet, clean, and kinda perfect Sai Wan is one of four beaches along Tai Long Wan, and it might just be the best one if you like your beaches peaceful and photogenic. On weekday mornings, it’s practically empty. The sand is soft and white, the water is clear, and the vibes are immaculate. Bring snacks, a beach mat, and enjoy a lazy afternoon tanning, swimming, or even camping if you're making it an overnighter. There are a couple of small local restaurants near the beach, where you can grab some drinks, ice creams, and simple local food—but don’t expect too much variety. It’s enough to keep you refreshed though, especially after the hike or swim. A secret lagoon & cliff jumping This is where it gets extra fun. Just a short walk and a bit of a careful climb over the rocks, and you’ll find a hidden lagoon pool slightly off the main beach. It’s a calm, tucked-away freshwater spot: not ideal for small children, but absolutely magical if you're steady on your feet and want something a little different. And for the adrenaline lovers: there’s a 5-meter cliff-jumping spot nearby. No lifeguards, so be smart, be careful and don't go alone. But if you're up for it, the view from the top and the splash below are unforgettable. Getting back: hop on a speedboat (but don’t miss the last one) Too tired to hike back after all the sun and swimming? Good news: there are speedboats that can take you directly from Sai Wan Beach back to Sai Kung Public Pier. The ride is bumpy, fast, and super fun—plus, the coastal views are gorgeous from the water. Expect to pay around – per person, one way. Tickets are bought from the restaurant on the beach. (You can also take a boat from Sai Kung Pier to the beach, this requires some haggling and negotiation at the pier.) A note of caution, Big Wave Bay can live up to its name, and on these days, the boat ride can tip over from exhilarating to outright scary! Cheapo tip: There are only a limited number of speedboats each day, and they stop running in the late afternoon or early evening—exact times vary depending on the day and season. If you miss the last boat, your only options are to hike back the way you came or camp overnight. So plan ahead, especially if you’re visiting on a weekday or during off-peak hours. Why I love it Of all the beaches in Hong Kong, Sai Wan is easily my favorite. It’s got that rare mix of natural beauty, low crowds, and hidden extras that make it feel like your own little discovery. Whether you’re looking for a peaceful sunbathe or an action-packed swim-and-hike day, this place has it all.
