Senmonorom (and the Mondulkiri province in general) is inhabited by the indigenous Pnong people. Pnong tribesmen and tribeswomen are often seen walking along major highways. The town is popular with NGO workers, loggers, and tourists both from outside Cambodia and from Cambodia's capital Phnom Penh.
