Renting a car is not a necessity to explore Cabarete and its surroundings, as the town is relatively compact and offers various transportation options. Taxis are readily available for local transportation, and there are also options like renting a scooter or bicycle for shorter trips. However, if you prefer the flexibility and independence of having a car, and you feel comfortable navigating the local roads, renting a car can be a convenient choice. Just be aware of the driving conditions and the local traffic habits, especially if you are not accustomed to driving in the Dominican Republic.
