San Cristóbal de las Casas Altitude: 2,120 m / 6,955 ft

Use 2,120 m / about 6,955 ft as the reference elevation for San Cristóbal de las Casas itself. The roughly 2,220 m figure comes from older material describing the average surrounding valley, so both numbers can appear without referring to exactly the same point.

For a traveler, the practical effects are cooler highland mornings and evenings and more noticeable hills or stairs. The city is below the CDC’s general 2,450 m / 8,000 ft sleeping-altitude threshold for altitude-illness risk, but individual responses still vary.

How high is San Cristóbal de las Casas?

City reference elevation: 2,120 m / about 6,955 ft
Why you may see ~2,200 m elsewhere: older INEGI planning material describes the San Cristóbal valley at an average elevation of about 2,220 m
Main travel effect: cooler highland conditions; hills and stairs may feel more noticeable for some visitors
CDC context: 2,120 m is below the 2,450 m / 8,000 ft sleeping altitude at which the CDC says unacclimatized travelers are generally considered at risk for altitude illness

Which elevation should you use?

For a simple city reference, use 2,120 m. That is the altitude INEGI gives for the cabecera municipal in its 2022 state geographic compendium.

Older INEGI planning material describes the average elevation of the valley where the city sits as about 2,220 m. The city and surrounding terrain are not perfectly flat, so both numbers can appear in references while describing slightly different things.

For trip planning, “about 2,100–2,200 m” describes the local highland setting; 2,120 m / 6,955 ft is the cleaner city figure.

Climate effect

San Cristóbal is in the Chiapas Highlands rather than the hot lowlands. Even when midday weather is comfortable, mornings and evenings can feel cool.

Can you get altitude sickness in San Cristóbal?

The CDC Yellow Book 2026 says an unacclimatized traveler proceeding to a sleeping altitude of 2,450 m / 8,000 ft or higher — and sometimes lower — is at risk for altitude illness. San Cristóbal’s 2,120 m city elevation is below that general threshold.

That does not mean nobody can feel the elevation. Individual response varies, and walking uphill may feel different if you arrive from sea level. Severe, persistent or worsening symptoms should not automatically be blamed on altitude; seek professional medical care when appropriate.
