Yes, there are vipers in Peru, and several species are medically important, especially in the Amazon and some coastal and Andean regions.

Quick Scoop: Short Answer

  • Peru has multiple species of pit vipers (family Viperidae), mainly in the genera Bothrops and Bothrocophias.
  • These snakes are responsible for most serious snakebites reported in the country each year.
  • Risk is highest in rural tropical areas (Amazon basin, some foothills and low mountains), and much lower in big cities and high, dry Andean zones.

Where vipers are found in Peru

  • Peru harbors at least 17 species of pit vipers, distributed across lowland rainforest, foothill forests and some coastal and montane areas.
  • They occur from near sea level in the Amazon and some coastal valleys up to around 3,000 m in certain Andean habitats, avoiding the driest southwest and the very highest puna.

Notable viper groups and examples

  • Most medically important species belong to the genus Bothrops (often called “jergĂłn” locally), which is widespread in tropical Latin America.
  • Studies list species such as Bothrops pictus (coastal areas near Lima), Bothrops barnetti , Bothrops chloromelas , Bothrops oligolepis , and Bothrocophias species in regions like the Amazon, Cusco, Piura and others.

How dangerous are they?

  • Viper bites account for the majority of Peru’s roughly 1,500–2,500 snakebite cases per year, with deaths typically in the single to low double digits annually when tallied nationwide.
  • Modern antivenom and rapid access to medical care mean that many bites are survivable if treated quickly, but they can still cause severe local tissue damage and systemic illness.

If you’re traveling in Peru

  • Main bite risk is for people hiking or working in rural Amazonian or forested areas; urban tourists on standard city itineraries face very low viper encounter risk.
  • Basic precautions include wearing boots and long pants on jungle or rural hikes, using a light at night, and seeking immediate hospital care (not traditional remedies) if bitten, so that appropriate antivenom can be administered.
