Few trips in Vietnam change the scenery as much: you leave the limestone islands of Lan Ha Bay behind and end up among the terraced hills of the Hoang Lien Son mountains. The journey has three parts: the boat from Cat Ba to the mainland, a long stretch across the Red River Delta and the climb to Sapa.
The bus is the main option. On booking platforms, tickets from Cat Ba to Sapa cost about $29 to $46 (November 2026), and the trip takes from about 9 hours.[1] A private transfer from Hai Phong is faster and much more expensive.
Cat Ba to Sapa by Bus
Combined bus and boat tickets cover the whole route, and cabin buses with lie-flat berths take you over the highway to Sapa.[1] Check that your ticket includes the boat or ferry from the island. Evening departures let you sleep on the way and wake up in cool mountain air. You can compare and book tickets on GoAsia.cc.
Cat Ba to Sapa by Private Transfer
If you travel as a group, a private transfer is the most flexible choice. Cars start from Hai Phong, so you take the ferry from Cat Ba to the mainland first. On booking platforms, a private car from Hai Phong to Sapa costs about $213 to $336 (November 2026) and takes from about 7 hours.[1]
