March Equinox at Chichén Itzá 2025 – Ultimate Visitor Guide

Introduction

Every year in the heart of the Yucatán Peninsula, the ancient city of Chichén Itzá becomes the stage for a remarkable moment of light, shadow and history. Around the spring equinox in late March, the sun aligns just so with the pyramid of El Castillo (also known as the Temple of Kukulkán) to produce a fascinating spectacle: a series of shadows that appear to form the body of a serpent slithering down the north-western staircase of the pyramid. Visiting during the March equinox is more than just seeing ruins—it’s a chance to connect with the ingenuity of the Maya civilization, feel the atmosphere of a cultural event, and witness one of the world’s most iconic archaeological alignments.

What Happens During the March Equinox at Chichén Itzá

The Phenomenon Explained

The equinox marks the moment when the Earth's axis is perpendicular to the sun, causing day and night to be nearly equal. At Chichén Itzá, this astronomical moment coincides with the architecture of the pyramid:

• The late afternoon sun casts triangular shadows down the stepped north staircase of El Castillo.

• These shadows snake downward and appear to join with the stone serpent-head carve at the base of the staircase.

• This effect typically occurs around March 20-23 for the spring equinox.

Symbolism & Significance

For the Maya, the feathered serpent deity Kukulkán represented creation, sky, earth and cycles of life. The visual “descent” of the serpent at the equinox may have symbolised renewal, fertility and the return of divine energy.
