Seal Watch at Halfway Rock: Portland’s Quick Escape to Wild Casco Bay
Aboard "EXPLORER" | $31 per passenger | Approximately 45 mins.
The skiff noses away from Portland’s working waterfront, engine humming, gulls heckling from pilings as if to test our resolve. Lobster boats idle and shift like old friends in a busy conversation, and the scent of bait and brine folds into the cool Atlantic air. On the open-to-air "EXPLORER," there’s no barrier between you and Casco Bay—only wind, salt spray, and the clean horizon pulling your gaze east. The bay flexes with tide, a living thing that swells against granite ledges and urges the boat forward. As the city shrinks behind you, the islands start their roll call: low spruce, weather-stained wharves, staccato flares of lighthouse white. This is a quick ride—45 to 60 minutes start to finish—but it’s a full immersion, a pocket-sized marine safari that compresses the essence of coastal Maine into a single breath of time.
Trail Wisdom
Layer for a Sea Breeze
Even in summer, offshore wind can run cool. Pack a light windproof layer—open-air seating means direct exposure to the elements.
Protect Your Eyes
Polarized sunglasses cut glare and make it easier to spot seals in the water and read the texture of swell.
Go Early for Calmer Water
Morning departures typically offer smoother seas and softer light, especially helpful for motion-sensitive travelers and photographers.
Stabilize the Shot
Use burst mode and a fast shutter speed to freeze wildlife from a moving boat; keep elbows tucked to reduce camera shake.

Halfway Rock Lighthouse was completed in 1871 to reduce shipwrecks on the exposed ledge; it was automated in 1975 and remains an iconic Casco Bay beacon.
