Practical info
Know before you book
The things that change a decision — not a retelling of the guidebook.
The bioluminescent bays need a dark night
Laguna Grande at Fajardo is the accessible one, paddled by kayak through a mangrove channel. Mosquito Bay on Vieques is the brightest in the world and needs a ferry or a short flight. Either way, book around the new moon — moonlight drowns the effect.
El Yunque requires a reservation
The only tropical rainforest in the United States forest system now uses timed vehicle reservations for the main road, released on a schedule and taken quickly. Guided tours include the permit; driving yourself does not unless you booked it.
It is a United States territory
US dollars, US mobile plans without roaming, US mains plugs, and no passport needed for US citizens. For everyone else the entry rules are the American ones, including ESTA or a US visa — which surprises European visitors expecting Caribbean formalities.
The distances are short
Old San Juan is twenty minutes from the Isla Verde hotels and Fajardo about an hour east. Ponce and the west coast are two to three hours. A hire car makes the island easy; public transport outside San Juan is thin.
Hurricane season runs June to November
The island was hit hard in 2017 and rebuilt; the risk is real but the low-season prices reflect it. August to October is the statistical peak. Outside those months the weather is warm and stable.
Old San Juan is an evening city
The cruise passengers leave in the late afternoon and the blue cobbled streets become local again — bars, live salsa and a very different atmosphere from the daytime. Stay for the evening rather than seeing it at noon.

Frequently asked
Puerto Rico: common questions
How many days do you need in Puerto Rico?
Five days covers Old San Juan, El Yunque, a bioluminescent bay and a beach. A week lets you add Vieques or Culebra, or the west coast around Rincón, which is a slower and very different island.
What does a tour in Puerto Rico cost?
Puerto Rico is not in our fifty-city price index, so we avoid a median figure. Prices follow US mainland levels rather than Caribbean ones: kayak bay tours and rainforest day trips are the core products and are priced accordingly.
Which bioluminescent bay should I choose?
Laguna Grande at Fajardo if you are based in San Juan — an hour away and done as an evening kayak trip. Mosquito Bay on Vieques if the effect itself is the point: it is the brightest recorded anywhere, and it costs a ferry or a small plane to reach.
When is the best time to visit?
December to April for the most settled weather at the highest prices, or May and November for nearly the same conditions at less. July to October is cheapest and overlaps the peak of the hurricane season.
Do I need a passport?
Not if you are a US citizen — it is domestic travel. Everyone else needs whatever the United States requires of them, including ESTA or a visa. It is worth checking early, because it is not the same as visiting an independent Caribbean country.
