Things to Do in North Puerto Rico
The north is really two trips wearing one name. On the coast you have San Juan, where the old walled city does most of the work: two Spanish forts, cobblestone calles, and enough good coffee to justify all the walking. Drive west on PR-22 and the island changes fast. Past Manati and Barceloneta the limestone hills begin, the mogotes, green humps that look more like southern China than the Caribbean, and underneath them runs cave country carved out by the underground Rio Camuy.
Here is the honest state of things in 2026. Old San Juan is open every day and as good as ever; the forts run nine to five. Cueva Ventana, the cave with the window over the Rio Grande de Arecibo valley, is back after four dark years and runs guided visits daily. Rio Camuy Cave Park, the headline act of the karst, is still behind a locked gate, with reopening dates that keep slipping. So plan the city on foot, plan the karst by car, and read the cave pages below before you drive an hour to find out for yourself.
The places worth planning around
-
San Juan
Old San Juan
The walking loop sanjuaneros give visiting family: two forts, the calles between them, and exactly one coffee stop.
-
Arecibo
Cueva Ventana
The cave with the window over the Rio Grande de Arecibo valley is open again. Guided only now, and the walk earns it.
-
Camuy
Rio Camuy Cave Park
The biggest cave system in the Caribbean is still behind a locked gate. Here is where the reopening actually stands.
Getting there
From San Juan, PR-22 is the road west: a toll highway that reaches Arecibo in about an hour in normal traffic, and noticeably longer at rush hour. Cueva Ventana sits off PR-10 south of Arecibo, roughly 75 minutes from the city. Old San Juan needs no car at all.
North Puerto Rico questions
Is Rio Camuy Cave Park open right now?
No. The park has been closed since late 2024 and remained closed as of July 2026, with no confirmed reopening date. Officials have described a phased reopening starting with Cueva Clara, but the announced dates have slipped more than once. Cueva Ventana, in the same karst country near Arecibo, is the cave you can actually visit.
Do you need a car to explore the north of Puerto Rico?
For the karst country, yes. Cueva Ventana and the limestone hill towns are spread along PR-22 and PR-10 with no useful public transit between them. Old San Juan is the exception: the historic district is compact and walkable, and if you do drive in, the Dona Fela and Paseo Covadonga garages sit on the Recinto Sur harbor side near the piers.
Is Cueva Ventana open, and do you need a reservation?
Yes. Cueva Ventana reopened in May 2024 after a long closure and now runs guided visits only, about 90 minutes with helmet and flashlight provided. Adult admission is $29 plus tax, kids 3 to 10 pay $10 plus tax, and children under 3 are not admitted. The operator takes reservations by phone and booking ahead is the safe play.
