The Sherpa'r Wyddfa bus network has attracted more than 70,000 passengers in a month for the first time.
The latest monthly figures reveal 72,296 people used the service in the Eryri area during August.
Cyngor Gwynedd says the network, which was relaunched two years ago, has seen passenger numbers rise by 79% compared to pre-Covid levels.
Cllr Dafydd Meurig, cabinet member for the environment, said: "Careful planning was carried out when the Sherpa’r Wyddfa bus service was re-designed to ensure that it offers both vital daily journeys for local people along with an important travel resource for people visiting the area."
"Working together with several partners, we are delighted to confirm that the Sherpa continues to offer an excellent network of bus services to transport people around the Eryri area in a sustainable way."
"Delivering a convenient, dependable and affordable bus network is a priority for Cyngor Gwynedd and we have recently completed a county-wide review of our services with a view of delivering the best possible services with the resources available."
"The latest passenger numbers for the Sherpa show what can be achieved when we work together with partners and plan routes that meet the needs of local people and those who visit the area."
"We would like to encourage those who can travel by bus to do so whether this is on a regular or less frequent basis. This helps make local bus services as sustainable as possible from a financial and environmental basis as well as supporting the case for further enhancements."
A council review of Gwynedd's bus services led to the introduction of new timetables where possible, along with standardised ticket prices based on distance in an effort to provide a fairer service.
The council says it's also worked hard to ensure integrated services that help encourage more people to leave the car at home and make the most of buses.
Sherpa'r Wyddfa is run jointly by Gwynedd and Conwy councils, along with Transport for Wales and the Eryri National Park.
