CARL RUSSO/Staff photo. GAZETTE: This is the place to be to escape the heat and boredom of summer in the city. Haverhill's YMCA's Camp Tricklin' Falls in East Kingston is packed for most of the summer with kids ages 4-16. They enjoy traditional camp activities such as archery, and also try newer activities like rock wall climbing. The kids even find quiet time in the large Native American-style teepee, which is part of the camp's landscape. The East Kingston fire dept. provided some fun and relief from the heat for the campers. Kids ages 4-16, are enjoying their summer at Haverhill's YMCA Tricklin' Falls camp in East Kingston. 7/21/2017.
