The reason we’re here

20–21 March 2027

Spring equinox at Chichén Itzá

El Castillo, Chichén Itzá

Around the equinox, the late-afternoon light draws a zigzag of shadow down the staircase of El Castillo, which looks like a serpent descending. It is best seen in the afternoon, roughly from 3 to 5 pm, and INAH runs a special operation for the huge crowds. Whether the Maya designed the effect is unknown.

Every year around 20–21 March, set by the spring equinox; INAH announces the exact access dates each year. The date changes each year by a set rule: check it before you travel. Source ↗

  1. Day 1 · Thu 18 Mar

    Arrive and wander

    A gentle first evening in Mérida: the main square, then a stroll down Paseo de Montejo.

    • Plaza Grande and the cathedral1 h

      The leafy main square of Mérida, with the cathedral on its east side. The cathedral was built between 1562 and 1598 with stone from a Maya temple of T’ho, the city that stood here before.

      What to see

      • The cathedral on the east side
      • The Government Palace and the town hall on the other sides
      • The shade of the old trees
      Time
      An hour, with no hurry.
      Tip
      Come after the afternoon heat, when the square cools down and the families come out. At three o’clock the stone and the benches are too hot for small legs.
      To eat
      Marquesitas, crisp rolled crepes with queso de bola, a favourite with children.
    • Paseo de Montejo1 h 30

      A wide, tree-lined boulevard inspired by the avenues of Paris, lined with mansions built with the henequen fortunes of around 1900.

      What to see

      • The old henequen mansions
      • The Monumento a la Patria
      • The shade of the avenue
      Time
      An easy walk, or a short taxi ride.
      Tip
      Take a taxi to the north end and walk back south: the pavements are wide, and the way back is easier after a day of travel.
      To eat
      Coconut ice cream, or a glass of agua de chaya, a green drink made from a local leaf.
  2. Day 2 · Fri 19 Mar

    Yellow town, cool water

    We drive east to Izamal, the yellow town, then on to Valladolid, where a swim in a cenote is waiting.

    • Izamal and its convent3 h

      A town painted yellow, where a 16th-century Franciscan convent stands on the base of a Maya temple. The Kinich Kakmó pyramid, about 35 metres high, rises a few streets away.

      What to see

      • The yellow convent and its arcaded atrium
      • The Kinich Kakmó pyramid
      • The horse-drawn carriages round the square
      Time
      Three hours, with lunch.
      Tip
      Visit the convent in the morning. By noon the yellow walls and the pale atrium floor throw back so much sun that the children will need hats and water.
      To eat
      Kiníc, pork cooked in sour orange, a dish Izamal calls its own.
    • Cenote Zací1 h 30

      A large cenote in the middle of Valladolid, a water-filled cave open to the sky, where the family can swim after the drive. A restaurant stands beside it.

      What to see

      • The cenote seen from the steps
      • A swim in the cool water
      • The old town streets nearby
      Time
      An hour and a half.
      Tip
      Wear shoes that grip, because the steps and the edge are wet, and keep sunscreen light or rinse it off: cenotes ask visitors to protect the water.
      To eat
      Longaniza de Valladolid, the local smoked sausage, with eggs.
  3. Day 3 · Sat 20 Mar

    The serpent day

    Chichén Itzá from opening time to the afternoon, when the shadow serpent shows on the staircase. It is the busiest day of the trip, so we go early and keep the children close.

    • Chichén ItzáAll day

      The great Maya city, with El Castillo, a pyramid about 30 metres high whose staircase is the centre of the equinox show. You can walk around it, but climbing has been forbidden since about 2006.

      What to see

      • El Castillo and the serpent heads at the foot of its staircase
      • The Great Ball Court
      • El Caracol, the round observatory
      Time
      A full day, with the show in the afternoon.
      Tip
      Arrive at opening. On equinox days in 2026 the ticket office stopped selling at 16:00 and the site was cleared before dark, so check INAH for 2027 and agree a meeting point with the children.
      To eat
      Poc chuc, grilled pork with sour orange, in the villages outside the site.
    • Convent of San Bernardino de Siena1 h

      A Franciscan convent of the 16th century at the end of the Calzada de los Frailes, a street of low coloured houses. A cenote is hidden inside its grounds.

      What to see

      • The fortified church front
      • The cenote inside the grounds
      • The Calzada de los Frailes at dusk
      Time
      An easy hour.
      Tip
      Walk down the Calzada de los Frailes late in the afternoon, when the light is warm and the heat has eased. It is a good gentle end to a long day.
      To eat
      Panuchos, fried tortillas stuffed with black beans and topped with turkey.
  4. Day 4 · Sun 21 Mar

    The city of the black jaguar

    Ek Balam in the morning, quieter than yesterday’s crowds, then a slow evening in Valladolid.

    • Ek Balam3 h

      A Maya city about 25 km north of Valladolid, whose name means black jaguar. Its great Acropolis still carries carved stucco figures.

      What to see

      • The Acropolis
      • The stucco figures on its front
      • The ball court
      Time
      About three hours.
      Tip
      Be there when it opens so you have the Acropolis nearly to yourselves before the heat and the tour groups arrive. Bring water and hats for everyone.
      To eat
      Lomitos de Valladolid, pork in a tomato sauce, a local dish.
    • Valladolid main square1 h

      The calm main square of Valladolid, with the church of San Servacio on one side and benches under the trees.

      What to see

      • The church of San Servacio
      • The shade of the square
      • The streets round it, painted in soft colours
      Time
      As long as the children stay happy.
      Tip
      Come at dusk after Ek Balam, when the square cools down. The benches are perfect for tired legs, and you can eat close by without a long walk.
      To eat
      Cochinita pibil tacos, pork slow-cooked in achiote and sour orange.
  5. Day 5 · Mon 22 Mar

    A swim, then the market

    We drive back to Mérida by way of Dzibilchaltún and its cenote, then finish at the city’s big market.

    • Dzibilchaltún3 h

      A Maya site north of Mérida, known for the Temple of the Seven Dolls, which the sunrise crosses through its doorway at the equinox, and for a cenote, Xlacah, where visitors can swim.

      What to see

      • The Temple of the Seven Dolls
      • The Xlacah cenote
      • The long white sacbé, or Maya road
      Time
      Three hours, with a swim.
      Tip
      We come two days after the equinox, so the dawn crowds are gone. Bring swimsuits and a towel, and go to the cenote after the ruins, when everyone is hot.
      To eat
      Sopa de lima, a lime soup with shredded chicken and fried tortilla strips.
    • Lucas de Gálvez Market1 h 30

      The main market of Mérida, a busy, covered place of fruit, spices, hammocks and snack stalls.

      What to see

      • Stalls of tropical fruit
      • Hammocks and embroidered blouses
      • The snack counters
      Time
      An hour and a half.
      Tip
      Keep the children by the hand in the narrow aisles, and buy hammocks at the stalls that fold them into a bag so they fit in a suitcase.
      To eat
      Salbutes and panuchos from the counters, with pickled red onion.
  6. Day 6 · Tue 23 Mar

    Last ruins, then home

    Uxmal in the cool of the morning and Kabah on the way back, before heading home.

    • Uxmal3 h

      A Maya city of the Puuc style, famous for the oval Pyramid of the Magician and a quadrangle of carved stone rooms called the Nunnery. It has been a World Heritage Site since 1996.

      What to see

      • The Pyramid of the Magician
      • The Nunnery Quadrangle
      • The Governor’s Palace
      Time
      Three hours.
      Tip
      Go first thing. By late morning in March the stone is hot, and the site has very little shade.
      To eat
      Cochinita pibil with pickled onion, in a village on the way.
    • Kabah1 h 30

      A quieter Maya site about 20 km south of Uxmal, whose Palace of the Masks has a front covered in hundreds of masks of the rain god Chaac.

      What to see

      • The Palace of the Masks, Codz Poop
      • The arch that marks the old road to Uxmal
      • The quiet of a small site
      Time
      An hour and a half.
      Tip
      Count the masks with the children, then keep your voices low: with few visitors it is the best place to hear the birds. The sun is hard here at noon.
      To eat
      Fresh lime water and a snack of fried plantain.

Day and night, equal

At the equinox the sun is over the equator and day and night are nearly equal. In 2027 the spring equinox falls on 20 March.

A serpent made of shadow

In the late afternoon around the equinox, triangular shadows on El Castillo’s staircase look like a snake crawling down. Nobody knows if the builders planned it.

On the route: Day 3, Chichén Itzá

Clap at the stairs

A clap at the foot of the staircase comes back as a chirp, a bit like a quetzal. Researchers explain it as the echo from the steps.

Crowds on the clock

Almost 33,000 people came to Chichén Itzá for the equinox in 2025, according to figures the press attributed to INAH.
