The Highlands Natural Pool is Passaic County, New Jersey most unique hidden gem. In 1935, the now Olympic-sized pool was carved out of a hillside, allowing the natural mountain stream to fill it. No chemicals are used in the pool, the fresh water comes straight from a mountain stream. The Highlands Natural Pool is adjacent to the 5,400 acre Norvin Green State Forest and offers dozens of area attractions and activities for kids of all ages. Besides diving, splashing and swimming in the pool, play a game of volleyball, go for a hike on one of the many trails on premise, have a picnic, or lounge around in the grass or on one of the lounge chairs. Both day passes and seasonal memberships can be purchased. Small group and private swimming lessons with highly-trained lifeguards are available for young children. Come out for a fun and unique day trip and splash around in one of New Jersey’s only natural pools! Visit the website for more information.
