Why is carry-on especially important for Cuba travel?

Cuban customs officers inspect checked bags more thoroughly than carry-on bags at José Martí International Airport in Havana. Travellers arriving with checked luggage report longer customs delays and more frequent searches. Carrying on also keeps your cash, medications, and valuables under direct control throughout the journey.

Do credit cards work in Cuba?

Most international credit and debit cards do not work in Cuba. US-issued cards are blocked due to the US embargo. Visa and Mastercard issued outside the US should theoretically work but frequently fail at Cuban ATMs and merchants. Cash — preferably EUR or CAD — is the only reliable payment method. Carry enough for your entire trip.

What currency should I bring to Cuba?

Bring Euros, Canadian dollars, or British pounds in cash. The Cuban peso (CUP) is the local currency — exchange your foreign cash at official exchange houses (CADECA) or hotel reception on arrival. US dollars attract a surcharge and exchange rates vary. Bring more cash than you think you need as ATMs are scarce and often out of service.

Can I bring medications to Cuba in my carry-on?

Yes, and you should. Basic medications including paracetamol, antibiotics, antihistamines, and stomach remedies are often unavailable or in short supply in Cuban pharmacies. Bring a comprehensive travel medical kit in your carry-on where you have direct access throughout the trip.

Does eSIM work in Cuba?

eSIM coverage in Cuba is extremely limited. Cuba's main carrier ETECSA does not support eSIM roaming agreements with most international providers as of 2026. You'll typically need to purchase a local ETECSA SIM card on arrival, or rely on hotel and casa particular Wi-Fi. Data speeds are slow and connectivity is inconsistent.

Carry-On Only for Cuba: Why It Matters More Here

Carry-on-only travel pays off in most destinations. In Cuba, it matters more than almost anywhere else. The combination of customs dynamics, cash-only economics, limited medical supplies, and the value of keeping your most important items within reach makes arriving without checked luggage a genuine strategic advantage, not just a convenience.

Customs: Why Checked Bags Draw More Attention

Cuban customs at José Martí International Airport in Havana operates differently from what most Western travellers expect. Checked bags are X-rayed and inspected more thoroughly than carry-on luggage. Travellers arriving with gifts, electronics, and supplies for Cuban contacts — a common and important part of Cuban travel culture — report that checked bags are more frequently opened and searched.

Cuba has a history of limiting the value of goods incoming travellers can bring duty-free (the limit has fluctuated with policy changes). Medications, electronics, and high-value goods that arrive in quantity in checked bags can attract customs questions and delays. Carry-on, which is visually smaller and subject to the same airport security screening as anywhere else, typically passes through faster.

Keeping everything in the cabin also means your bag never leaves your sight from departure to arrival.

Cash Is Essential: Keep It in the Cabin

Cuba is one of the last truly cash-dependent travel destinations in the world. This is not a minor inconvenience — it's a fundamental logistical reality that shapes how you pack and plan.

The cash situation:

US-issued credit and debit cards are completely blocked under the US embargo
Even non-US Visa and Mastercard cards frequently fail at Cuban ATMs and point-of-sale terminals
ETECSA Wi-Fi vouchers, casas particulares (private accommodation), paladares (private restaurants), and most tourist activities require cash payment
ATMs in Havana are unreliable — they run out of cash, decline foreign cards, and charge high fees

What this means for your carry-on: Bring your entire trip budget in cash, carried on your person or in your carry-on bag. EUR, CAD, and GBP exchange well at official CADECA exchange houses. USD can be exchanged but attracts a surcharge. Do not put cash in a checked bag.

A money belt worn under clothing is the right approach for carrying large sums through airports and in busy areas like Havana Vieja and Varadero resort zones.

Medications: Pack Everything You Might Need

Cuba's healthcare system is widely praised for its doctors and medical expertise, but the supply of medications — particularly over-the-counter and basic pharmaceuticals — has been inconsistent for years. Pharmacies in Havana and other cities sometimes lack paracetamol, antihistamines, stomach remedies, and basic antibiotics that travellers to other countries could pick up at any corner store.

Pack a medical kit in your carry-on that includes:

Paracetamol or ibuprofen (fever and pain)
Antihistamines (allergic reactions, insect bites)
Loperamide (traveller's diarrhoea — common on Cuban food and water adjustment)
Oral rehydration sachets
Antiseptic wipes and plasters
Any prescription medications you take regularly (bring more than enough for your trip)

Keep medications in their original packaging with pharmacy labels. Cuban customs permits travellers to bring personal medication for their own use.

What to Bring vs Buy in Cuba

Unlike most travel destinations, Cuba is not a place to rely on buying things locally. Supermarket shelves are often sparse, and tourist-oriented shops at resorts carry a limited selection at high markup.

Bring from home:

All toiletries and personal care items (full-size, since you're skipping checked bags — keep liquids in carry-on limits)
Sunscreen and insect repellent
Medications (see above)
Any technology you need (phone charger, adapter — Cuba uses Type A/B outlets, same as the US and Canada)

Things to exchange or source locally:

Cuban art, cigars, rum, and music from paladares and markets — these are the authentic Cuba experience
Local sim card from ETECSA on arrival (if available and roaming doesn't cover your needs)

Packing for Cuba's Climate

Cuba is tropical with distinct wet (May–October) and dry (November–April) seasons. Temperatures range from 24–32°C in coastal areas year-round. The packing list mirrors other Caribbean destinations:

4–5 lightweight tops in breathable fabrics
2 pairs of lightweight trousers or shorts
1 light layer (air-conditioned restaurants in Havana can be cold)
Sturdy walking shoes and sandals
A lightweight rain layer for wet season travel

Cuba's colonial streets in Havana, Trinidad, and Cienfuegos are cobblestoned — sandals alone won't suffice for full days of walking.

US Travellers: Additional Considerations

US citizens travelling to Cuba must ensure their visit qualifies under one of the authorised categories under US law (general tourism remains restricted as of 2026). Travel from the US is permitted under categories including support for the Cuban people, educational travel, and others. Keep documentation of your travel purpose in your carry-on in case of questions on return to the US.
