Black bear attacks in Rocky Mountain National Park are rare but can occur. While the park is home to a significant black bear population, incidents involving humans are infrequent. However, as visitor numbers increase and bear habitats overlap with human activities, the potential for encounters rises. This guide provides essential information on black bear behavior, attack prevention, and safety measures for park visitors.
What is the Current Situation of Black Bear Attacks in Rocky Mountain National Park?

Rocky Mountain National Park, spanning 415 square miles of diverse mountain environments, is home to a thriving black bear population. While exact numbers fluctuate, it’s estimated that 20-30 black bears inhabit the park. Despite this presence, reported attacks on humans are extremely rare.
