Summer is officially here, and it seems like it’s going to be a hot one. Luckily, New Jersey has plenty of places where you can cool off. Instead of heading down the Shore, why not switch things up and try one of the Garden State’s many swimming holes? By definition, a swimming hole is any lake or river that is deep enough to swim in, and there are plenty to choose from. We’ve comprised a list of 13 NJ swimming holes for you to enjoy, varying from manmade lakes to natural pools and more. 

1. Oxford Furnace Lake, Oxford Township

Oxford Furnace Lake was once used for flood and erosion control and has been transformed into a serene lake for all to enjoy. Not only is the Oxford Township lake great for swimming and relaxing on the beach, but it offers kayak and canoe rentals, boating, fishing, and more. There are also recreation areas and places to explore. You might even get to see the musky, a large fish that sticks its head out of the water.

The lake is open daily from 11 a.m. to 6 p.m.

Located on the coast of the Wharton State Forest is the Atsion Recreation Area, where you can swim and sunbathe on the gorgeous Atsion Lake. Similar to other NJ swimming holes on this list, this one offers a beach with shallow and deep areas perfect for swimmers of any skill level. There are also barbecue grills, picnic areas, playgrounds and nature crafts for children to enjoy, and concession stands where you can grab a bite to eat. While there, you can also explore the Batsto Village, an exhibit about 19th-century commerce and agriculture.

The Atsion Recreation Area is open daily for swimming from 10 a.m. to 6 p.m.

The property also features picnic areas, places to play horseshoes and volleyball, and a novelty shop.
