🇵🇷Things to Do in Puerto Rico
From the colorful colonial streets of Old San Juan to El Yunque's rainforest - the essential sights, and how to keep your own record of them.
Travel guide - last updated September 2026
Puerto Rico packs an unusual range into a compact island - a 500-year-old walled Spanish colonial city, the only tropical rainforest in the US National Forest system, and some of the brightest bioluminescent bays on Earth. As a US territory, it also offers an easy entry point for American travelers seeking a genuinely Caribbean, Spanish-speaking experience without a passport. Here are 5 places worth building a trip around.
Top attractions
The sights most first-time visitors build an itinerary around.
Old San Juan
A UNESCO World Heritage colonial old town with colorful buildings, cobblestone streets, and the imposing Castillo San Felipe del Morro fortress guarding the harbor.
📍 San Juan
🚉 Nearest station: Sagrado Corazon on the Tren Urbano, then a bus or taxi into the old city; the free trolleys loop the blue-cobbled streets between the two forts.
El Yunque National Forest
The only tropical rainforest in the US National Forest System, with waterfall hikes, dense jungle trails and views stretching to the coast on clear days.
📍 Rio Grande
🚉 There is no bus service into the rainforest: it is 45 minutes east of San Juan by car, and vehicle reservations are now required for the main road corridor - book before you set off.
Bioluminescent Bays
Puerto Rico holds several of the world's brightest bioluminescent bays, including Mosquito Bay in Vieques, where microorganisms light up the water with every paddle stroke on a moonless night.
📍 Vieques & Fajardo
🚉 Mosquito Bay on Vieques is the brightest: ferries run from Ceiba, or small planes from San Juan, with kayak tours launching after dark - Fajardo's Laguna Grande is the mainland alternative.
Flamenco Beach, Culebra
Regularly ranked among the best beaches in the world, with soft white sand and calm turquoise water on the small island of Culebra, a short ferry ride from the mainland.
📍 Culebra
🚉 Ferries from Ceiba take 45 minutes to Culebra, then a publico van covers the 4km to the beach - book the ferry online well ahead, as visitor spaces are limited.
Camuy River Cave Park
One of the largest cave systems in the Western Hemisphere, carved by an underground river, with guided tours through massive limestone chambers.
📍 Camuy
🚉 The caves are 90 minutes west of San Juan with no public transport - a hire car is needed, and the park has reopened only partially since the 2017 hurricanes, so check before travelling.

Open MyPassportStoryPlanning questions
How many days do you need in Puerto Rico?
5-7 days allows time for Old San Juan, El Yunque, a bioluminescent bay tour and a beach day or two - add extra days for a side trip to Vieques or Culebra.
What's the best time to visit Puerto Rico?
December-April is the dry season and the most popular time to visit. Hurricane season runs June-November, peaking August-October.
Is Puerto Rico good for a first-time visit?
Yes - as a US territory it's straightforward for American travelers (no passport or currency exchange needed), with well-developed tourism infrastructure and English widely spoken alongside Spanish.
Do I need a visa to visit Puerto Rico?
As a US territory, Puerto Rico follows US entry requirements - US citizens need no visa or passport for domestic travel, and other visitors follow standard US visa/ESTA rules. Check the official visa information for your nationality: travel.state.gov.
What are some things to do in Puerto Rico on a tight budget?
Walking Old San Juan's streets and forts, hiking El Yunque's trails and relaxing on public beaches like Flamenco cost little to nothing - a public-tour bioluminescent bay kayak trip is one of the few worthwhile splurges.
Can I rent a car in Puerto Rico, and what licence do I need?
Yes, and outside San Juan it is close to essential - the island's bus network barely reaches the rainforest or the west coast. As a US territory, Puerto Rico accepts any valid foreign licence for visitors, and US licences work exactly as at home; an International Driving Permit is only needed if yours is not in English. Minimum age is usually 21 with a surcharge under 25. Tolls are electronic through AutoExpreso, billed via the rental company, and road signs are in Spanish with distances in kilometres but speeds in miles per hour.
