Since most populations of feral horses are in the western part of the country, see if you can plan a trip to a state like Nevada, Utah, Colorado, or New Mexico. You can also try to visit wild horse populations in the salt marshes of the East Coast, like the Outer Banks.

Feral populations in North America are typically closely monitored. The BLM administers American horses, which are regularly rounded up and made available for adoption. These horses are held at BLM facilities until they are picked out and adopted.

After a competition, the horses are auctioned off. The proceeds help maintain the remaining captured Mustangs. Canadian authorities consider wild herds nuisance animals. Sometimes, horses are rounded up by ranchers or simply shot to preserve the grass for cattle. There are groups dedicated to their preservation.

This is for your own safety as well as the horse. Feral animals are not used to humans. They may also carry infectious diseases, or react violently to your presence. Never attempt to feed wild horses. This can make them dependant on humans, putting them more at risk. If you find feral horses that look underweight, call a local authority. They should contact the herd owner or a charity that will try to get an appropriate food source to them safely. Observing horses living free is a privilege. Remember their safety and your own makes the experience even better. Interacting with them will only ruin future visits for you and others. You want to see them living wild, not make them dependant on humans. Never attempt to capture wild horses. In the United States and elsewhere, capturing feral or wild horses is a federal crime, and may only be done by representatives of the Bureau of Land Management (BLM).
