Cartagena itinerary: how many nights, and what each day holds

Days by kind of trip

Your trip	Nights	What they hold
A stopover, a long weekend	Two	One full day: the walled city at the right hours, one sunset on the wall. No islands.
A first visit	Three	Two full days, a city day by the clock and a boat day, plus the afternoon you land and the morning you leave.
A first visit, for the water	Four	Three full days, one of them ending with a night on an island.
A slower trip, or a day trip	Five	Four full days: one more for the fortress, Getsemaní and a sunset cruise, or Palenque, Totumo or the Aviario.
Off a cruise ship	Hours	One plan for the hours ashore: the cruise port page.

Why three, in a city you can cross on foot. The distances are short; the cool hours are shorter. Inside the walls the streets stay below the site’s walking line until about 9:45 in February, but only until about 8:00 in October. So the 3.1 km loop, about 47 minutes on foot at 4 km/h, needs a morning of its own, and the wall needs a sunset. The islands take a whole day: the day boats leave 8:00 to 8:30 and are back at the dock about 16:30.

The fourth night is a night on an island: the beach after the day boats leave, the morning before they return, and no boat on your flight day. The fifth gives room. The fortress, Getsemaní and a sunset cruise get a day of their own, or the day goes to Palenque, the Totumo mud volcano or the Aviario Nacional. In the rougher-sea months it is also where a cancelled boat day goes.

Choose the nights and your month. Each row is one day from 6:00 to midnight over the month’s felt temperature in the shade: pale where you can walk, brick where you should not. Give the weekday of day 1 and the plan marks the likely ship days.

Every block comes from one rule, the guide’s own line, not a health authority’s. In the streets, where the houses block the wind, walk while the shade feels like 35 °C (95 °F) or less in still air. On the walls and the fortress hill, which get the sea breeze, the line is 33 °C (91 °F) with the breeze. The loop is the walled city page’s, with its hours for each month; the fortress visit starts at the 7:00 opening (Castillo San Felipe). Island boats run 8:00 to 16:30 on the 5-stop tour (Rosario Islands). Museums open at 9:00 and fill the hot hours in the streets, with lunch and the pool; at noon the shade feels like 36 °C (97 °F) in February and 37 °C (99 °F) in October.

What changes in a wet month

• The walks move earlier and get shorter. From May to November the loop runs from 6:00 to between about 7:15 and about 8:00, against 7:00 to about 9:45 in February.
• The fortress has one window, and it is short. The hill has no shade, so it never counts from 10:00 to 15:30. Its morning window ends between about 7:15 and about 7:45, or the hill is over the line at opening; a late window before closing opens only in January, February, March, April, November and December.
• The wall stays warm after sunset in May, June, August, September and October: up for the sunset, down soon after.
• The murals wait for the evening: the cool morning ends too soon after the fort.
• Rain on 7 to 12 days a month, by the national weather service’s 1991 to 2020 normals; the museums double as shelter (best time to visit).
• The sea is typically calmer, so the boat day follows the city day.

All twelve months

The windows the plans use, month by monthFelt temperature in the shade by month and hour, 2016 to 2024. Sea: typical model values. Ship days from the 2026-27 port schedule, which does not cover July and August.

The sea runs against the weather. From December to March, the dry months, the northeast trade winds blow and the crossing is typically rougher; from May to November, the wet months, it is typically calmer, with April and July in between. The port captain’s office (DIMAR) decides on the day: it uses a flag system to keep small boats in port or to call them back early. A yellow-flag notice for 22 to 24 February 2023, one event, gave waves of 3.5 m and ordered boats back to the dock by 15:30 (DIMAR notice).

The rule in the plans. In a rougher month the boat goes on the first full day, so a later day can take it if the flags are up; in a calmer month it follows the city day. If your trip spans the turn from November to December or from March to April, put the boat in the calmer month: November, or April.

Which boat. The 5-stop Rosario Islands day tour runs 8:00 to 16:30. The Rosario catamaran takes 7.5 hours. On Viator, the 5 island hop. All the ways compared: Rosario Islands, Cartagena islands.

A shorter crossing. Tierra Bomba’s north shore is 7 to 20 minutes across the bay. The Tierra Bomba beach day at Punta Arena runs boats back 14:00 to 17:00 and charges no park or dock taxes (Tierra Bomba).

On a ship day expect more people in the plazas while the ships are in: the most common call docks at 7:30 and sails at 18:00. Over the 2026-27 season the port schedule has ships in port most often on Sundays (32), then Wednesdays (22) and Thursdays (21); Fridays have the fewest (9). The pattern shifts month by month, so the plan uses your month’s own dates.

Start the morning loop at first light and go to the museums at opening. With a weekday set, the switch marks each likely ship day (ships on at least half of that weekday’s dates in your month) and moves the walled city day off it when another day can swap. July and August are outside the port’s 2026-27 cruise schedule.

With children

Sleep where there is a pool, or on the beach in El Laguito, where Hotel Caribe lists three pools. Keep the walled city to the loop and the free gold museum, and look for the sloths in Parque del Centenario. At the fortress children 6 to 13 pay 16,000 COP and those under 6 go free. For a first boat day, Tierra Bomba is 7 to 20 minutes away by boat.

Off a cruise ship

You have hours, not days. The most common call docks at 7:30 and sails at 18:00, and the terminal is 3.2 km from the walled city. Take the city day from these plans and skip the Rosario Islands: the day boats are back about 16:30, close to most all-aboard times. Tierra Bomba is the one short crossing. Timed for your ship: Cartagena cruise port.

With a day trip

In the five-day plan, swap the fortress day. Totumo: the half-day mud volcano tour picks up from about 8:15 or 13:15 and takes 4 hours. San Basilio de Palenque: the Palenque tour with a community guide meets 8:00 at the Clock Tower and takes 5 to 6 hours. The Aviario Nacional on the road to Barú charges foreign adults 90,000 COP, is open Monday to Sunday 9:00 to 17:00, last entry 16:00 and fits a half day with the aviary tour with hotel pickup. All three compared: day trips from Cartagena.
