About Oahu Adventure Tours, LLC

Local Waikiki experience behind every Oahu Bus Tour.

Oahu Bus Tours is built around something simple: local operators, a smaller 14-passenger bus, and people who know how to help visitors plan a better day on Oahu.

Meet Frank Baumann and James Lewis

Frank and James have been business partners in Waikiki for two decades. Their background is rooted in tourism, hospitality, vacation planning, and helping visitors experience Hawaii in a way that feels personal, local, and easy. Oahu Bus Tours brings that experience into a simple small-group and private tour format.

Frank Baumann

Waikiki tourism & hospitality experience

Frank moved to Waikiki 20 years ago and brings two decades of experience from Hilton, Waikiki, and countless travel clubs. He understands what visitors need when planning a Hawaii vacation: clear information, smooth logistics, and a local person who can help make the day easier.

His experience around Waikiki tourism helps Oahu Bus Tours serve families, private groups, cruise visitors, and travelers who want more than a generic bus ride.

James Lewis

Local Oahu operator & family man

James Lewis has Native Hawaiian roots and grew up in Hawaii. His father, Sonny Lewis, was an iconic Waikiki businessman whose local roots helped shape James' connection to the island and the visitor industry.

James is also a father with a little boy, and he brings that family-minded approach into the way Oahu Bus Tours helps visitors plan safe, comfortable, and memorable days around the island.

Why this matters when you book a tour

When visitors book an Oahu tour, they are trusting someone with their vacation time. Frank and James built Oahu Bus Tours around a smaller, more personal 14-passenger bus experience instead of a giant motorcoach feel.

That means easier communication, more personal service, and a local operator feel from people who have spent years helping travelers enjoy Hawaii.
