Where can I see a fer-de-lance in Costa Rica?

Fer-de-lance (terciopelo) inhabit humid lowland and foothill forest on both slopes, including the Sarapiquí and Caribbean lowlands. They’re found on guided night herping walks, where an experienced guide locates the well-camouflaged, ambush-hunting snake safely and at a respectful distance.

When is the best time to see one?

The wet season, roughly May to November, brings more activity, and the fer-de-lance is primarily nocturnal, so night walks are essential. Sightings are a matter of night effort in the right habitat with a trained eye, rather than a fixed peak week.

Is it safe to look for a fer-de-lance?

With an experienced herping guide, yes — observation is done at a safe distance with no handling. The fer-de-lance is venomous and medically significant, so a trained guide who controls distance and group positioning is essential. Lyferr lists guides with verified herping track records.
