Size: 42 acres (Granite Island Preserve); 1.7 acres (Kintner Salt Marsh)
Trails: A loop trail about a mile long that starts and ends at the trailhead parking lot, with 3 short spur trails taking hikers to scenic overlooks (two with benches) on the shore. The Story Trail, featuring a book for young readers or work from Students at the Vinalhaven School is 0.2 miles.
Features: The whole spectrum of Vinalhaven granite, from uncut ledges to abandoned paving stones, can be seen as you walk around this preserve. Hikers will enjoy trailside moss gardens, great views across the Basin, and abundant opportunities for wildlife observation, including large groups of harbor seals hauling out on tidal ledges.
Be Aware: The lush growth of mosses and lichens on the granite ledges and forest floor cannot tolerate foot traffic; please stay on the trail. At the shore, please stay on the ledges and rocks to avoid trampling on the salt marsh vegetation. Please respect our neighbors' privacy and be aware of the preserve boundaries. If you walk too far along the shore, you'll be in someone's yard.
From the ferry, turn left and go 0.4 miles on Sands Rd., then left again on Old Harbor Road. After 2.2 miles, the road becomes dirt; the gravel parking lot and trailhead will be on your right in another 0.2 miles.
