For rental cars, a temporary driving license is required for visitors and may be obtained with a valid driving license upon arrival at the airport, at the police station in Castries or at the car rental offices. Rental cars or scooters can be booked at the airports, hotels or car rental companies. Rates average about $50 per day.

Drivers in St Lucia drive on the left side of the road. You’ll find there are some hairpin turns on the roads here, drive carefully and honk your horn while going around the turns.

Privately run minibuses serve as the main ground transportation for much of the island for local residence. The routes form a big loop around the island and stop between the main towns along the way. Buses run on varied times depending on the route, but most run until around 7pm (except for the busy Castries-Gos Islet corridor where they run until after 10pm). Buses do not operate on Sundays. Fares range from $1 to $3. Minibuses have a green number plate with an M prefix.

In urban areas buses are only permitted to stop at designated bus stops. In rural areas, if there’s no bus stop nearby, you can wave buses down anywhere on the route as long as there’s space for the bus to pull over. When you want to get off, announce your intention by calling out 'stopping driver' well in advance of your stop.

Taxis in St Lucia have a blue number plate with a “TX” prefix. Before you hire a taxi, confirm the fare. Taxis can be very expensive with cross island trips costing about $80 to $90. Fares are about $70 from the airport to Marigot Bay. Rates do vary by destination, the number of people, amount of luggage and the company. Note that on longer journeys prices are somewhat negotiable. Some of the major taxi services on the island include Saint Lucia Taxi Service, Saint Lucia Airport Transfers, Saint Lucia Executive, Saint Lucia Airport Shuttle, Real Saint Lucia Tours, and many more.

St Lucia is not the easiest place to cycle in. Many roads are narrow, poorly lit and lack sizable shoulders. Furthermore motorists are not used to seeing cyclists on the road and don't always leave enough space.

Water taxis can be hired to travel to virtually anywhere on the west side of the island, with the most popular routes running between Rodney Bay in the north and Marigot Bay or Soufrière in the south.
