When it comes to wildlife viewing, you’d be hard pressed to go to any National Park and not see some local fauna, however some parks definitely stand out as top spots for viewing unique wildlife. So, if getting your eyes on a grizzly, a gator, a sea lion, a rattlesnake or an elf owl is top of your list, grab your hiking boots and a good pair of binoculars and head to one of the best National Parks for wildlife viewing. 

Remember, you should tread lightly and give all wildlife a wild berth – you’re a guest in their house, after all. Enjoy wildlife from afar, and if you’re exploring the hiking trails or backpacking, make sure you read our articles on what to do if you meet a bear, mountain lion or moose on the trail.

About 90 minutes off the coast of North Angeles lie five virtually untouched islands surrounded by a remarkable diversity of rare wildlife, some of which can only be found here. Kayak and snorkel among whales, sharks, dolphins, and spiny lobsters, hike with bats and soaring bald eagles overhead and among lizards, tree frogs and foxes, and chill out with sea lions and seals basking on the secluded beaches. A visit here provides a rare glimpse into what California’s coastline would have been like before people arrived in large numbers, as the islands have enjoyed almost total seclusion despite regular ferries from Ventura.

Situated in southwest Alaska, Lake Clark requires a small plane to reach it, which keeps annual visitation below 5,000 which means if you want to explore its smoking volcanoes, stunning coastline and craggy peaks, you’ll have the wilderness to yourself. Lake Clark is home to the world’s largest sockeye salmon fishery as well as the imposing grizzly bears that feed on them, then in the valleys you’ll find caribou, moose, wolves and lynx if you’re lucky.
