Previously, in early February 2026, Sun Group handed over and converted the Yoko Onsen Quang Hanh resort to the world's leading hotel group Hilton for management and operation.
Accordingly, Hilton Quang Hanh Onsen Resort will be the new name of Yoko Onsen Quang Hanh resort built and put into operation by Sun Group from 2020 in Quang Hanh ward, old Cam Pha city (now Quang Hanh ward, Quang Ninh province).
This is a resort with a special source of mineral water exploited deep underground, temperatures up to 55 degrees Celsius and especially salty, ranked as one of the most famous Brom mineral water locations in the world with Brom content from 49-51mg/l and very good for health.

With a new name, Hilton Quang Hanh Onsen Resort becomes Hilton's third resort in Vietnam and the first onsen resort of this international hotel group in Southeast Asia.
The cooperation with "giant" Hilton is a strategic step by Sun Group to bring resort tourism in Quang Ninh in particular and Vietnam in general to a new level.
The entire resort was transferred by Sun Group to Hilton, including 178 villas, 38 washitsu rooms and the Public Onsen area.
Each room category at this resort is equipped with its own onsen and hot-cold sauna system, allowing guests to enjoy a full hot mineral treatment right in their own resting space.
Under the operation of Hilton Group, the resort is oriented to become an international-class health care resort destination, where traditional onsen experiences are placed within the reference system of global service standards.
With the brand philosophy of putting customer experience at the center, the hotel group not only brings a professional operating management system, but also the ability to connect destinations with a wide network of international tourists, especially the high-end customer segment and long-term stayers.
