The Gasa Hot Springs (Tshachu) are located near the banks of the Mo Chhu River. They are among the most popular hot springs in Bhutan, attracting not only tourists but also local visitors throughout the year. With improved road connectivity, it has become much easier for people to reach the site, and guesthouses are available nearby, which can be booked in advance.

The hot spring complex consists of ten ponds—five designated for women and five for men—along with two exclusive ponds for VVIPs and VIPs. Each pond has a different water temperature and is believed to offer unique healing properties, allowing visitors to choose the one most suitable for their needs.
