Clube Todo-o-Terreno de Oeiras (CTTO) is a Portuguese off-road club founded in 1994 to bring together people who enjoy four-wheel-drive activities, shared learning and outdoor adventure. Based in Barcarena, the club organizes activities for members and welcomes families and friends to explore new routes, landscapes and cultures. Its outings have taken participants across Portugal and to destinations including Spain and Morocco, with activities ranging from regional drives and longer international trips to navigation and communications workshops and social gatherings.

CTTO encourages participation whether visitors have an SUV, a 4x4 vehicle or simply an interest in off-road travel. Membership provides access to club events and member benefits, including information about offers on goods and services related to the activity. The club also recognizes a social-support purpose and promotes responsible conduct, respect for nature and sustainable activity through its code of conduct. Members and prospective participants can visit the club’s headquarters on Thursdays from 9 p.m. or contact the organization for information about joining and upcoming events.
