Congratulations, you’ve made the fabulous decision to view majestic brown bears within Katmai National Park! Although a well-known and popular activity in Alaska, you might be wondering, how is this safe? Besides, an Alaskan brown bear can reach upwards of 1,400 pounds and can stand up to 10 feet tall! Not to mention, there are no fences or protective barriers in Katmai. Sometimes, the only thing between you and an enormous coastal brown bear is some rushing water and swimming salmon.
