if your not stupid, no you won't. Katmai is known for having the highest density of grizzlies and a lot people go there specifically for viewing the bears. I had a friend who went there for a couple weeks last summer with a professor for doing research and such and he came back unscathed. But i also had a friend get attacked by a bear with riding her bike in the anchorage area....so you might get eaten. good luck haha. why are you going?
