Yes, Puerto Rico is one of the easiest Caribbean destinations to travel independently: it uses the US dollar, US citizens need no passport, and English is widely understood alongside Spanish.
The challenge is cost and transport, not difficulty. Hostel dorms in
San Juan run about US$30 to 45 a night, guesthouses elsewhere US$90 to 150, and a rental car US$40 to 70 a day. The ferry from Ceiba to
Culebra or
Vieques costs around US$2 but sells out on weekends. Plan on US$75 to 130 a day on a backpacker budget, with San Juan to
Rincon taking 2.5 to 3 hours by car.
Ten days is the best amount of time for a first trip to Puerto Rico, enough for San Juan, El Yunque and either the west coast or the offshore islands.
With 5 days, stay in the east: 2 nights in
San Juan and 2 in
Fajardo for El Yunque and the bioluminescent bay. With 10 days, add 6 to 7 nights split between
Isabela,
Rincon and
Cabo Rojo. Two weeks lets you do the full loop including
Culebra,
Vieques and
Ponce. Distances are short (San Juan to Ponce is about 1.5 hours), but island ferries and slow mountain roads eat more time than the map suggests.
Only partly: in Puerto Rico you can manage San Juan and the islands of Culebra and Vieques without a car, but the west and south coasts realistically need one.
In
San Juan, walking, Uber and the Tren Urbano cover most needs, and the Cataño ferry costs about US$0.50. An Uber from San Juan to the Ceiba ferry terminal runs roughly US$60 to 100, and the ferry to
Culebra or
Vieques about US$2, with públicos or rental jeeps on arrival. For
Rincon,
Cabo Rojo and
Ponce, rent a car at US$40 to 70 a day plus tolls; público vans exist but run irregularly.
The must-visits in Puerto Rico are Old San Juan, El Yunque National Forest, a bioluminescent bay and Flamenco Beach on Culebra.
Give
Old San Juan 2 days for El Morro and San Cristóbal (US$10 covers both) and the small plazas between them.
El Yunque is 45 minutes from the capital; the La Mina Trail or El Yunque Peak Trail fills a day. Kayak tours into
Fajardo Bioluminescent Bay cost about US$50 to 70.
Flamenco Beach is a 2-night trip by ferry from Ceiba. With more time, add
Rincon for surf and sunsets and the
Cabo Rojo Lighthouse, 2.5 to 3 hours west of San Juan.
If you are short on time in Puerto Rico, skip Mona Island, the Arecibo Observatory and the central mountain forests, and focus on the east.
Mona Island needs camping permits and a rough boat crossing of 3 to 4 hours, so it suits only a dedicated multi-day trip. The
Arecibo Observatory Visitor Center is interesting but the telescope itself collapsed in 2020, making it a lower priority.
Toro Negro and other mountain forests involve slow, winding roads of 1.5 to 2 hours each way. On 5 days, I would also leave
Ponce and the west coast for a second trip and spend the time between
San Juan and
Fajardo.
