INTRODUCTION
Tikal is a Maya city inside a national park — the most famous archaeological site in Central America, set in 575 km² of protected rainforest near Guatemala's northern border. At its peak around 750 AD, the city had a population of roughly 100,000. By 900 AD it was empty. The jungle took it back, and stayed there for nearly a thousand years.
What you can visit today is the ceremonial centre: a 16 km² core of temples, plazas, palaces and ball courts, linked by old stone causeways. Most of the wider site is still buried. The standing structures only hint at how big this place really was.
Don't underestimate the walking. The main visiting loop covers around 5 km on uneven ground, often in heat above 30°C. A full day is the minimum to see the highlights; two days is much better.
