There are so many destinations all over the world, but the tourist spots in the U.S. are more than enough to keep the explorer's heart satisfied as well. Lonely Planet trained the spotlight on the country's best sights and sounds, as they released their top U.S. picks for travelers who are planning to hit the road this year.

According to Lonely Planet's list, Philadelphia is the best city to visit in 2016, boasting a colorful and affordable experience that benefits every kind of tourist. The country's first and only World Heritage City, Philly, has its own distinct flavor with craft breweries, locavore restaurants and a down-to-earth atmosphere grounded in its historic roots.

Just at the heels of Philly is Natchez, Mississippi, a destination known for its history and architecture. This year is an especially good time to drop by the area because it's celebrating its 300th anniversary with more than 300 events throughout the year. There are plenty of interesting activities that visitors will have a tough time picking one, from the Natchez PowWow in March, the Great Mississippi River Balloon Race in October and many more.

Rounding up the top three destinations in the U.S. is the renowned Yellowstone National Park, which highlights the rugged beauty of the country's natural resources in 9,000 square kilometers of wilderness. The park is a stunning place to visit all-year-long and a must-visit hotspot for every American explorer at some point in their lives.

In a report from CNN, Lonely Planet's Eastern U.S. destinations editor Rebecca Warren explained what makes their lineup relevant to all kinds of travelers.

"There are so many amazing places to visit in the U.S. every year, but what distinguishes this list is the timeliness," Warren pointed out. "I think we can get lost in what's in your own backyard. It reminds people that there is so much to do in America, and it changes every year."

The rest of the places in Lonely Planet's list are: Birmingham, Alabama; Alaska; Somerville, Massachusetts; Northwest Arkansas; San Antonio, Texas; Southern New Mexico; and Milwaukee, Wisconsin.

The country is so vast and varied with so many different cultures to get to know and learn from. Before venturing to foreign countries, it might be a good idea to brush up in your own. Lonely Planet didn't just offer their picks on the must-visit U.S. places in 2016, but they also crafted a quiz on the website to help travelers figure out where they should go.
