The festival is scheduled to take place from 10 - 12 July 2026, with camping available throughout the weekend. Visitors can enjoy performances from a range of local, national, and international artists, with music spanning genres such as world music, electronic, Afrobeat, folk, and dance.

Tonnau is designed to be family-friendly, with a variety of activities for children and young people, including workshops, crafts, games, and interactive entertainment. Alongside the music programme, attendees can explore food and drink stalls, wellness activities, and creative spaces throughout the festival site.

Located on the north-west coast of Anglesey, the festival benefits from a scenic rural setting close to the sea, making it an attractive destination for both local residents and visitors. Its focus on community, creativity, and cultural exchange has helped establish Tonnau as one of the island’s distinctive summer events.
