When you see it on the map, Puerto Rico seems like a small island.
But, Puerto Rico is not just an island, it is an archipelago; three inhabited islands and several uninhabited islands comprise the islands of Puerto Rico.
I have been taking tourists to the islands of Puerto Rico for almost 20 years.
In this article, I will cover every major island in Puerto Rico:
You will find Borikén (The Island of the Brave and Noble Lord,” as the Taino Indian called it) 1,067 miles southwest of the Florida Keys.
Puerto Rico is a commonwealth of the United States. You don’t need a passport or currency change to travel to this non-incorporated US Territory.
The United States Federal Constitution, Rights, and Laws apply to Puerto Rico. Spanish and English are Puerto Rico’s official languages.
Even your cell phone will work in Puerto Rico, and you will get no roaming charges because all of the major cell phone companies do business in Puerto Rico.
You will be safe and protected and have no communication problems in Puerto Rico.
The main Island has a tropical rainforest and a dry forest.

“La Isla Nena” (the girl island) or Bieké (small land), as the Taino called it, is just 21 miles long by only 3 miles wide.
Vieques is famous for many things; let’s explore some of them:
Historians say South American Indians arrived in Vieques 1,500 years before Christopher Columbus “discovered” Puerto Rico in 1493.
Mosquito Bay, the brightest bioluminescent bay in the world, is in Vieques.
One of the first things you will see in Vieques is horses roaming free.
Many locals own horses and let them free during the day.
Vieques is famous for the role it played in US Defense.
The US Navy used the Island of Vieques for target practice for over sixty years. They left Vieques in May 2003.
Playa Negra (Black Beach) is a black sand beach in Vieques.

La Isla de Culebra, or Snake Island, is the smallest inhabited Island in the Puerto Rican Archipelago.
Culebra is just 7 miles long by 3.5 miles wide.
It is famous for its beaches, but Flamenco Beach stands out as one of the best beaches in the world, according to Conde Nast Traveler.
You can also kayak, scuba dive, or snorkel with sea turtles in Culebra. Culebra’s slow-paced way of life will help you “disconnect” from the rush of daily life.
Public transportation is almost inexistent in Culebra, and we recommend renting a four-wheel drive vehicle.
This small Island is 17 miles west of Puerto Rico’s main Island and 12 miles west of Saint Thomas.
To get to Culebra from San Juan, you have two options: fly from SJU Airport Culebra or drive to Ceiba and take the Ferry.
The flight from San Juan to Culebra will take about half an hour, and the ferry ride will take close to 35 minutes.
There are no direct ferries from San Juan to Culebra; the ferry leaves from Ceiba, an hour and a half drive from San Juan.
Below is a Google Map that shows the location of Culebra:
Culebra is worth visiting; the beaches and the wildlife are spectacular, and Los Culebrenses (the people from Culebra) are hard-working, noble people that will treat you like you’re one of them.

Culebrita is a one-mile long by one-mile wide small uninhabited island west of Culebra.
The little Island is a natural reserve; conservational laws protect the animals and plants of Culebrita.
Most people don’t know this, but Culebrita is the star of puertorico.com.
Our main photo, the one with boats and yachts on a pristine beach, is from Culebrita.
Culebrita is famous for its beaches; it has 6, an old Spanish lighthouse, and tidal pools on the rocks.
In Playa Tortuga (Turtle Beach), you will swim and snorkel with turtles that are not shy or scared of humans.
A 25-minute hike will take you to the lighthouse.
The view from there is impressive.
Below is a video of a day in Culebrita:
Getting to Culebrita is a challenging task; first, you have to go to Culebra and, from there, charter a private boat that will be inexpensive.
Most of those charters include chairs, umbrellas, and food and refreshments.
One thing that people visiting Culebrita agree on is that the trip is worth it.
You will have a small paradisiac island for yourself for a day.
