Our Kawasaki Mule UTVs are designed for every corner of Vieques — rugged enough for off-road paths, comfortable enough for full-day exploring. From the ferry to the beaches and back, Fun Brothers gives you the most dependable way to experience the island on your own schedule.
Experience the Island on Your Own Terms
Fun Brothers makes it easy to see Vieques without depending on taxis or tour schedules. With your own Mule, you can visit every corner of the island — from the calm waters of Sun Bay to the cliffs overlooking the Caribbean — all at your own pace.
Rental Requirements, Shuttle & Deposit Details
To ensure a smooth and reliable experience for all guests, please review the following guidelines before your rental.
Rental Requirements
Drivers must be 21 years or older with a valid driver’s license.
All passengers are required to wear seat belts while the vehicle is in motion.
Helmets and safety gear are provided and must be used when required.
Fuel charges may apply depending on the return level of the vehicle.
Deposit Details
A $500 refundable security deposit is required for all Mule rentals.
The deposit is processed at pickup and returned once the vehicle is inspected and cleared.
Refund times vary by bank but generally process within 2 to 4 business days after return.
This policy helps ensure vehicle accountability and maintains the high quality of our fleet for all guests.
Special Offer
When you book your Mule rental, you automatically qualify for a 10% discount on our BioBay Tours.
A special discount code will be included with your receipt after booking — no need to request it separately.
Cleaning Policy
Please return all Mules in a reasonably clean condition. Vehicles returned excessively dirty — including heavy mud, sand, or debris inside the cab or cargo area — are subject to a $55 cleaning fee.
This policy ensures fair use and helps our team maintain every Mule in top condition for the next guest. For reference, cleaning a heavily soiled vehicle like the one shown can take over an hour to restore properly.

Vieques is filled with hidden beaches and off-road access points that are difficult to reach without the right vehicle.
A Fun Brothers Mule gives you the power and clearance to explore freely, even on rough terrain. Our Mules are perfect for travelers who want independence, convenience, and a true island experience.
Enjoy smooth handling, strong suspension, and easy steering ideal for exploring both paved and unpaved roads with confidence.


See Vieques the way it’s meant to be seen — at your own pace, in comfort, and with the confidence of a reliable vehicle.
Book your Mule today and let Fun Brothers help you experience the best of the island.
For your convenience, all our tours snorkeling, BioBay, stargazing, and more depart from the same central meeting point. Please arrive 15 minutes early for check-in, orientation, and prompt departure.
We also recommend packing light as space is limited. Here’s why: our van makes several drops and pickups throughout the evening. Guests who finish earlier tours stay in the van while we continue shuttling others. Because of that, there’s no secure place to leave bags except in the van and only on the final return trip, when we won’t be coming back for more guests.
So please bring minimal gear so we can keep everything smooth and efficient.
It’s also where you’ll find our rental station, open 7 days a week from 9 AM to 5 PM. Stop by to rent gear, check in for your tour, or get local tips before you explore!
Well see you at the meeting in Esperanza.
