Picnicking in special places throughout the US has become a choice for many people. We’ve come up with 5 of the top picnicking areas across the US.

Cumberland Islands, Georgia

This national shore(海岸) is a perfect picnicking place. It’s an undamaged place in the Deep South with over 50 miles of hiking trails(小径) and beaches. The trails are lined with trees covered in Spanish moss.

Grant Park, Chicago

If you are looking for delicious food in Chicago, go for taste of a 20-day, lake-front foodie festival that happens each year. Grab a spot near the fountain to enjoy your picnic, appreciate the city scenery and lake views and relax. If you are there on July 4^th, be sure to plan the day to include the firework display at the Navy Pier.

Cranberry Islands, Maine

Here, you’ll find natural picnicking with island views. The islands are a delightful group of islands about 20minutes by private boat or ferry service. Bring a picnic basket along for the ride as it’s a romantic picnic area to take your friends or go for a family outing to visit the islands.

Red Rock Canyon, Nevada

If you happen to be in Las Vegas, Red Rock Canyon and the nearby Spring Mountain Ranch State Park offer a welcome rest. Situated just 19 miles west of Vegas, it’s a trip worth taking. There are plenty of picnic areas along the drive and in nearby Spring Mountain Ranch State Park which also offers outdoor theaters and concerts in summer months.

The Point Lobos State Reserve has often been called “ the crown(皇冠) jewel of the State Park System”.
