Great Island Commons

4.3(3 reviews)New Hampshire, USA East

What a beautiful location. Even if you don’t intend to dive, it is worth the dive to visit this park. The coast is rocky and the entry is easy. What more could you want?! Coming into Portsmouth from the South on 1A about .5 mile North of Foyes Corner, turn right on 1B (Wentworth Rd.) In 1.84 miles, turn right into the Great Island Commons.

McKinney Park, Lake Winnipesaukee

4.2(5 reviews)New Hampshire, USA East

One of the only public accesses on Lake Winnipesaukee. Good stuff to see. There is a full service dive shop only about 4 miles away. Directions to McKinney Park:Take 93 north to Concord. In Concord get off on 15E (393/202/4/9) Follow to the end of 393 merges onto 2ndary road (Weathervane on Right) Continue for about 2 miles. At first set of lights take a left onto Main St Chichester. At the end of Main Street go left onto 28 North. Drive on 28 North for 40 minutes. At the Alton Circle cont. in 28 North into Wolfeboro. There will be a 90 degree bend in the road, about a mile beyond there will be the hospital. Across from the Hospital is Clark Road. Turn left onto Clark Road. Follow to end. Park at top of hill and walk down. Staging area at bottom. Swimming off to the right towards Wolfeboro Bay is not very exciting. If you swim off to the left it is a great dive with lots of marine life...bass, perch, sunnies to name a few. The average usually will go no deeper than 40 feet. Someone with good air consumption and diving skills could see the wall that goes from 60 feet to 110.
