I have spent years chasing quiet coastlines and wild preserves across New York State, but Shelter Island still caught me off guard in 2026. The island stretches for 27 square miles off the shores of Long Island, and while it is famous for hotels and fine dining, I think its natural beauty is the real headliner. The Mashomack area is one of the wildest corners, where native birds and turtles move through woodlands and lakes. After all, what could be better than a Hamptons-adjacent escape that feels a world away? I arrived expecting charming inns, but I left with muddy boots, a camera full of wildlife photos, and a new appreciation for the Mashomack Preserve. If you are planning a day trip or a longer stay, these are the hikes I would not skip.

Mashomack Red Trail: The Easy Woodland Loop

I started my trip with the Mashomack Red Trail, a 2.4-mile loop that winds through the preserve's wooded areas. This path feels remote and peaceful, making it a great choice for hiking, jogging, or cycling. It only reaches about 30 yards in elevation, so it is genuinely easy. I was surprised by how much variety it packed into a short walk: lakes, marshes, and creeks appeared one after another. Although dogs are not allowed, I saw several families enjoying the route with children. Most hikers complete the loop in 45–47 minutes, and I can confirm that it is a perfect warm-up before exploring the rest of the island.

Joan C. Coles, Red, Yellow, Blue, and Green Loop

For a longer adventure, I followed the Joan C. Coles, Red, Yellow, Blue, and Green Loop. At 7.89 miles, this route takes hikers around the exterior of the Mashomack Preserve and offers lovely coastline views. Because it includes parts of the Mashomack Red Trail, I recognized a few stretches from earlier, but the extended route quickly felt new. The loop is popular, so expect to pass other travelers, especially on sunny weekends. I also noticed signs that cross-country skiing and cycling are allowed here, which makes it a year-round destination. The hike took me between 2 hours and 30 minutes and 2 hours and 35 minutes at a relaxed pace.

Mashomack Red, Yellow, Green, and Joan C. Coles Loop

If you love wildlife watching, this 5.6-mile trail is a must. It explores the southern parts of Shelter Island and follows the coastline, giving me incredible glimpses of the surrounding waterways. The landscape is quiet and pristine, which made bird watching feel almost private. I kept my binoculars close and was not disappointed. This trail is ideal for hiking and running, but dogs are not allowed, likely to protect the sensitive habitats. Most hikers say it takes around 1 hour and 50 minutes, and that matched my experience. If you only have one afternoon, this is a strong contender.

Blue Trail: A Camera-Ready Wildlife Route

The 4.6-mile Blue Trail on the east coast may be my favorite for pure observation. Some sections forbid running and biking, which shows how carefully the island protects its flora and fauna. I treated this as a walking-only route and was rewarded with a slow, immersive experience. Shelter Island is known as a haven for herons, hawks, and osprey, so I brought my camera and stopped often. The trail took me about an hour and a half, though I lingered longer to watch birds glide over the water. Does a trail need massive elevation or mileage to be memorable? Not here.

Coecles Harbor Marine Water Trail

Not every Shelter Island adventure requires hiking boots. The Coecles Harbor Marine Water Trail is a 5-mile round trip best explored by kayak or small boat. I rented a single kayak from Kayak Shelter Island, where tours and rentals are available; as of my latest visit, a full-day single rental cost $90.00, though I always check current 2026 prices before booking. Paddling the shoreline gave me a completely different perspective on the island's fall foliage, spring flowers, and local wildlife. Because rowing is more demanding than walking, I would call this moderate. Plan for 3–4 hours if you want to take a slower pace and explore.

Mashomack Red and Joan C. Coles Trails

For anyone traveling with kids or planning a one-day trip, the combination of the Mashomack Red and Joan C. Coles Trails is ideal. This 2.4-mile route is quicker than the longer combined loops but still delivers steady, scenic terrain. I saw families walking, jogging, and carefully stepping off the path to peek into the woodlands—just remember to keep the trail in sight. Most people finish in 45–47 minutes, so there is still plenty of time to see the rest of the island.

Laspia Family Trail: A Tiny Trail with Big Charm

The Laspia Family Trail is only 0.2 miles long, but it packs in local history and natural beauty. It opened in 2018 and was named for the Laspia family, who worked at the island's nature preserve for years. I strolled near Sanctuary Pond and read the informative signs that explain the landscape and its people. It took me about 10 minutes at a gentle pace, though I stopped often to watch turtles and look for birds. Because it is so short, it is not the best trail for bike riding, but it is perfect for a quiet nature walk.

Quick Trail Guide

Shelter Island is remarkably close to New York City, but its meadows, shorelines, ponds, and forests make that proximity feel impossible. I went looking for a peaceful alternative to the Hamptons, and these scenic hikes delivered exactly that. Whether you want a quick family walk, a long coastal loop, or a kayak route along the water, this Long Island gem deserves a spot on your 2026 travel list.
