Leaving the underground world of Phong Nha-Ke Bang National Park for the limestone karsts of Cat Ba Island is a trip from one geological wonder to another. The caves of Central Vietnam are quiet and ancient, while Cat Ba is the lively gateway to Lan Ha Bay. The route suits travelers who want to skip Hanoi and go straight from the jungle to the sea.
Cat Ba is an island, so the trip combines road travel with a ferry or speedboat crossing. Almost all services are overnight cabin buses that let you sleep through most of the long journey. You can book on GoAsia.cc.
Phong Nha to Cat Ba by Bus
The most direct way is a bus that runs from Phong Nha all the way to Dao Cat Ba. Booking platforms sell it as one ticket that includes the ferry or speedboat crossing and the last stretch to Cat Ba Town, so you do not have to buy tickets at different terminals.
VIP and Cabin Buses
The Cabin 22 and VIP buses have individual compartments with curtains. On booking platforms, tickets cost about $36 to $39 (October 2026). Buses leave in the evening, from about 20:00 to 23:59, with one at 00:45, and the journey takes 10 hours 30 minutes to 11 hours.[1]
Double Cabin for Couples
From Quang Binh, the Single Cabin and Double Cabin buses leave between 20:15 and 23:30. The Double Cabin is a wide berth for two people, cozy if you carry a lot of hand luggage. Booking platforms list these tickets at about $39 to $60 (October 2026), with a journey time of about 11 hours 45 minutes.[1]
Phong Nha to Hai Phong by Bus
You can also take a Cabin 22 bus to Hai Phong, which leaves at 20:30 or 23:00. On booking platforms, tickets cost about $45 (October 2026) and the journey takes about 13 hours.[1] This is a good choice if you want to spend a day in Hai Phong or the direct buses to Cat Ba are full.
From Hai Phong, the Dong Bai ferry to Cat Ba runs every 30 minutes from 05:00 to 18:00 and takes about 30 minutes. A bus from Hai Phong to Cat Ba, road plus a short ferry or speedboat, takes about 2.5 hours.[2]
