Quick answer
About 7 hours of driving for the full coastal loop (roughly 475 km / 295 miles) with no traffic, based on our OpenStreetMap routing. Plan a long day at minimum; most people split it over several days.
- East coast to west coast (Fajardo to Rincón): about 3 hours.
- San Juan to Ponce: about 1 h 40. San Juan to Mayagüez: about 2 h 24.
- Traffic around San Juan at rush hour, rain and road work can add a lot.
- Puerto Rico’s land area is about 3,424 square miles (US Census).
Our loop is routed through San Juan, Fajardo, Humacao, Yabucoa, Guayama, Ponce, Cabo Rojo, Mayagüez, Aguadilla and Arecibo. A realistic plan spreads it over 3–5 days.

Driving rules visitors should know
- Distances in kilometers, speeds in mph. Road signs show distances in km, but speed limits are in miles per hour.
- Gas is priced per liter.
- Tolls are electronic (AutoExpreso). PR-22, PR-52, PR-53 and PR-66 have toll plazas with no cash lanes. Rental cars usually include a toll tag and bill you afterwards, so ask at the counter.
- Signs are in Spanish: PARE = stop, CEDA = yield, SALIDA = exit, DESVÍO = detour.
- Your US license works. International visitors can drive on a valid home license for a limited period. Check with your rental company.
Is driving in Puerto Rico easy?
On the expressways (PR-22, PR-52, PR-2), yes. In old town centers and in the mountains, roads get narrow, curvy and pothole-prone. Drive defensively, expect sudden stops and lane changes, avoid driving mountain roads after dark if you're new to them, and keep extra time for rain.
Can you get around without a car?
In the San Juan metro area, mostly yes: walk, take Uber or taxis, or ride the Tren Urbano (one line, Bayamón to Sagrado Corazón) and AMA buses. Outside the metro area it's hard. Públicos (shared vans) run between some towns, but schedules are informal. For a loop of the island, rent a car (see renting a car).

How big is Puerto Rico?
