Paddling to the Twin Lights: Kayaking to Thacher and Straitsmouth Island

Thacher and Straitsmouth Island by Kayak

Just off the coast of Rockport, Massachusetts, Thacher and Straitsmouth Island feel close enough to touch yet far enough to feel like an adventure. One with twin lighthouses rising from low granite cliffs, the island has long guided ships through the Gulf of Maine. The other just a short 30 min paddle away. For kayakers, it offers something even better: a short but unforgettable journey across open water to one of Cape Ann’s most iconic landmarks.

Setting Out from the Mainland

Most kayakers launch from our shop on Bear Skin Neck, but you can also launch from Pebble Beach. From our shop, Straitsmouth Island is only a mile trip, and Thacher 2.5 miles. Tides, wind, and swell can change quickly, turning a relaxed paddle into a test of skill. Checking marine forecasts and timing your trip for light winds and slack tide is essential. Our staff are always happy to provide you with guidance.

As you push off, Rockport’s granite shoreline slowly recedes, replaced by open horizon and the rhythmic sound of paddle blades slicing through the water. The twin towers of Thacher Island grow larger with each stroke, their white forms standing in sharp contrast to the dark blue sea.

Wildlife Along the Way

The crossing often comes with company. Harbor and Gray seals are frequent companions, surfacing nearby with curious eyes before slipping silently beneath the water. Seabirds wheel overhead—cormorants, gulls, and terns diving for fish stirred up by tidal currents. On especially calm days, you might spot schools of baitfish rippling the surface, or even the distant blow of a whale farther offshore.

The waters between Rockport the Islands are rich with life, and paddling quietly through them offers a front-row seat to the coastal ecosystem.

Reaching the Island

Landing on Straitsmouth and Thacher Island is permitted on the boat ramp near the middle of the Island. Both islands are open to the public but are animals and plants are strictly protected. The Thacher Island and Straitsmouth Island Association staff the islands June-August with volunteers. If you visit during these months you may even get to climb to the top of a lighthouse and visit the historical museums there. 

On your return trip, take a look at the mainland and how it appears rugged and timeless, its quarries, headlands, and villages shaped by the same forces pushing against your kayak.

A Paddle That Stays With You

Kayaking to either Island isn’t about distance or speed—it’s about presence. The open-water crossing sharpens your senses, the wildlife keeps you alert, and the island itself anchors you in New England’s maritime history. It’s a trip that rewards preparation and respect for the sea, offering in return a deep sense of connection to the coast.

For those willing to watch the weather, plan carefully, and paddle with intention, Straitsmouth and Thacher Island stands as both a destination and a reminder: some of the best adventures begin just beyond the shoreline.
