Caribbean ↗Several islands (Turks and Caicos above all, also the Bahamas and Jamaica) jail visitors for a single stray bullet or cartridge in their luggage; empty every bag and pocket before you pack.
Caribbean ↗From August to October keep a free last day before your flight home and check the national hurricane centre daily; airports close when a named storm approaches.
Caribbean ↗Wearing camouflage clothing is illegal for civilians in several islands, including Barbados, Antigua, Saint Lucia, Saint Vincent, Grenada, Dominica, Trinidad and Tobago and Jamaica; leave it at home, children's clothes included.
Puerto Rico ↗Entry follows US rules: international visitors need a US visa or ESTA as for the mainland, and US citizens need no passport from the mainland.
Puerto Rico ↗Road distances are signed in kilometres but speed limits are in miles per hour; fuel is sold by the litre.
Puerto Rico ↗Ferries to Vieques and Culebra sell out and are often disrupted: book ahead and have a small-plane backup.
Puerto Rico ↗El Yunque National Forest uses timed-entry reservations for the main road (PR-191) at busy times: book on recreation.gov before you drive — check current rules.
San Juan area ↗Hurricane season runs June to November: keep flights and hotels flexible and follow official advice.
San Juan ↗Old San Juan's blue cobblestones are slippery when wet and heavy for bags: rolling suitcases go from the car to the door, never on a walk.
San Juan ↗Hurricane season runs June to November, peaking August to October: check the National Hurricane Center outlook, keep flights flexible, and follow official advice.

Questions and answers

answered by Voykit editors · dated

Is San Cristóbal the same ticket as El Morro?

Usually yes; confirm the validity at the desk.

Checked 2026-09-29 · Voykit desk

Is San Cristóbal worth it if I have done El Morro?

Yes if you like tunnels and outworks: it is bigger and cooler inside. If you only have time for one fort, choose El Morro at opening.

Do I need a separate ticket?

Usually one National Park Service ticket covers both forts; confirm the validity period at the desk.

How long do I need?

60 to 80 minutes; 45 if you skip the tunnels.

Is San Cristóbal good in the heat?

Better than El Morro: the tunnels and galleries give shade. The batteries are still open to the sun.

Can I visit with a stroller?

It is hard: there are many steps in the tunnels. Use a carrier.
