Expect a compact, educational 45-60 minute stop focused entirely on a large, active leaf-cutter ant colony. A guide explains their complex society, how they cut and carry leaves, the fungus they farm underground, the role of the queen, and the different castes. You'll stand around a well-lit outdoor setup with clear views of workers marching along trails and into the nest. It's genuinely interesting if you like nature documentaries come to life, but it's not a hike or wildlife adventure; it's more like a very good science-center demo in the open air. The whole thing is easy, flat, and usually combined with other nearby stops.
Best time is the dry season (December-April) when trails are less muddy and ants are highly active. Expect to pay around $35-55 per person for a small-group tour including transport from San Jose. One honest tip: choose the version that includes a good close-up look at the fungus garden and queen chamber if offered; skip any add-on that promises "interacting with ants" or photo ops holding leaves, it's unnecessary and the natural marching lines are far more impressive. Bring bug spray and wear closed shoes.
