Two glacial lakes and an upland forest are attractive features of Green Lakes State Park. The park is also home to the 18-hole Green Lakes State Park Golf Course. Hiking, snowshoeing and cross-country skiing on the park's 10 miles of trails and fishing in the lakes are other popular activities. Pets okay on leash. Camping is also available. The great hiking trails here can also be used for mountain biking.
From Rt. 481 or 690 in Dewitt NY head east on Bridge St. which turns into 290. As you approach the end of 290 take a left on Minoa. If you reach Manlius Ctr rd. which is also 257, make a u-turn and go back about 100ft. Immediately after turning on to Minoa there is an Erie Canal Path parking lot on the right. This is a great place to start. You will ride out of the parking lot and up the 100 ft and left on Manlius Ctr. the trail starts about a quarter mile down on the right side of the road. There is a dirt parking area here also if you want to risk it. You can't really miss the entrance to the trail.
