Almost every packing list for Guatemala is written for a tropical country, and almost every visitor is cold on their first night. Antigua sits at roughly 1,500 metres and the lake at 1,560, which is the single fact a Guatemala packing list has to be built around.
What genuinely earns its place
A warm layer, and a real one. Fleece or a light down jacket, not a hoodie. Highland evenings are cool in every month of the year, and the western highlands around Quetzaltenango are properly cold.
Walking shoes with grip. Antigua's streets are cobbled and uneven, the ruins are rubble in places, and Tikal involves real distance on uneven ground.
High-factor sun protection. At altitude the sun burns faster than it feels, on days that are not hot. This catches more visitors than the cold does.
A rain layer, May to October, for the afternoon downpour that arrives on schedule.
And a light long-sleeved shirt for the Petén, where the insects rather than the sun are the issue, along with repellent that you actually intend to use.
A reusable water bottle, because the altitude and the walking dehydrate people faster than they notice, and because filtered refills are widely available in Antigua and at the lake.
For the volcanoes, specifically
Acatenango is a gear problem, not a clothing problem.
Below-freezing temperatures at the summit camp, wind, and a pre-dawn climb. Proper boots, gloves, hat, thermal layers and a headtorch, most of which reputable operators rent — and renting is the sensible choice rather than carrying a mountain kit for one night.
Take the operator's gear list literally. People who treated it as a suggestion are the ones in the incident reports.
Pacaya needs shoes with grip and nothing else special. A walking pole helps on the loose volcanic scree if your knees are the complaining kind, and the operators usually have them.
What to leave
Beach gear, unless the Pacific or Río Dulce is specifically on your plan. This is not that trip.
Heavy guidebooks, and formal clothes for anywhere outside a Guatemala City business meeting.
And most of the medical kit. Antigua and the capital have good pharmacies; carry what you personally need rather than a general kit.
Bulky toiletries, which are cheaper to buy on arrival than to carry, and which take the space you will want for the way home.
The altitude and the flight
Small aircraft are a volume problem rather than a weight problem. For the Flores sector at 145,1 nautical miles this rarely bites, but camera cases and tripods are rigid and get discussed at the aircraft rather than at booking. The allowance is calculated by weight when you quote in the app; tell us if you carry bulky gear. The specific aircraft is assigned on confirmation, based on passenger count, baggage and the destination field.
Ask with real dimensions before you book if you are carrying anything unusual. We show a "from" price per route; the final fare depends on the date, the group and the baggage, and is confirmed in writing before booking.
For the markets
Cash in small denominations, because a market stall cannot break a large note and the exchange becomes your problem.
And a bag with space, because textiles are the thing people buy here and they take more room than expected. A folded huipil is small; three blankets from Momostenango are not, and people routinely buy an extra bag in Antigua to get it all home.
The seasonal difference
We fly year-round. In the rainy season the pilot in command decides; if weather stops a flight, it is rescheduled at no cost. November to February: the coldest nights. Add a layer beyond what you think you need.
March to May: the warmest and driest, and the strongest sun.
May to October: the rain layer, quick-drying clothes, and shoes you do not mind getting muddy.
Year round: something that dries. Highland humidity and afternoon rain mean cotton stays wet, and one quick-drying set changes how a week feels.
And a small torch. Power cuts happen in the highland towns, and Antigua's streets are deliberately dim after dark.
Frequently asked questions
What is the most important thing to pack?
A real warm layer. Antigua and the lake sit above 1,500 metres and evenings are cool in every month.
Do I need hiking boots?
Walking shoes with grip for the towns and Tikal. For Acatenango, proper boots — which reputable operators rent.
What about Acatenango gear?
Below-freezing at the summit camp, so thermals, gloves, hat and a headtorch. Rent rather than carry it, and take the list literally.
Do I need beach things?
Only if the Pacific or Río Dulce is specifically on your plan. This is not that trip.
What about sun?
High-factor protection. At altitude the sun burns faster than it feels, and it catches more visitors than the cold does.
Anything for the markets?
Cash in small denominations, and a bag with space for textiles.
