Dhow trips can be booked through this recommended agency. The owner is a proud local who employs knowledgeable Omani captains who speak a variety of languages. An overnight camping trip on a beach in one of the khors (rocky inlets) costs OR55 per person (minimum two people) and includes all equipment, dinner and breakfast.
If you have a specific interest (such as seasonal birdwatching), the guides will be happy to tailor a trip for you. The agency office is next to Diwan Alamir Hotel.
