Around Union River Bay: the towns near Eagles Nest

Most people blow through these mainland towns on the way to the bridge. They're where you actually live during a stay — and each one is good for something different.

The mainland coastline around Union River Bay near Eagles Nest

Last updated August 3, 2026

Eagles Nest sits on Union River Bay in Trenton, the last town on the mainland before Mount Desert Island. Fan out from the house and you're on a coast of small towns wrapped around two bays — Union River Bay and Frenchman Bay — most of them quieter than anything on the island. Here's what each is actually for.

Trenton — the gateway, and home base

This is where the house is: on the mainland side, minutes from the one bridge onto Mount Desert Island. Trenton is the hinge the whole trip turns on. It's home to Hancock County–Bar Harbor Airport (BHB), the seasonal regional airport nearby in Trenton, and to the new Acadia Gateway Center — the 11,000-square-foot transit and visitor hub that opened here in 2025, about 18 minutes away, with around 300 free parking spaces, where you leave the car and catch the fare-free Island Explorer shuttle into the park and Bar Harbor (current schedules). It's also lobster-pound country: the classic roadside Trenton Bridge Lobster Pound is about 14 minutes away, steam rising off the kettles by the causeway. And for the easiest family evening of the trip, Timber Tina's Great Maine Lumberjack Show (127 Bar Harbor Rd) runs right here in Trenton, minutes from the house — nightly 7:00 pm shows from mid-June through the end of August, with first shows over Memorial Day weekend, and in its 31st season in 2026. It is reliably fun, it asks nothing of you after a long park day but showing up, and the current schedule is worth a quick check before you go. For how to use all of this — which airport to fly into, and how to time the bridge — see getting here & drive times, and for the island itself, Bar Harbor & MDI.

Ellsworth — the hub (where you provision)

About 12 minutes north, Ellsworth is the last full-size town before the house and the one everyone calls the "gateway to Acadia and Downeast." It's the practical center of the region: the main groceries, pharmacies and hardware, plus a historic Main Street along the Union River. This is where you do the real shop on the way in — fill a cooler here and you won't have to backtrack once you've settled onto the shore. For the specific stores and a couple of tables worth the drive, see where to eat & provision.

Lamoine — the quiet shore

Lamoine is a small town on a peninsula reaching into Frenchman Bay, and its centerpiece is Lamoine State Park (23 State Park Road) — a low-key waterfront park right on the bay, with a boat launch, picnic areas, a nature center and a seasonal campground (open roughly mid-May to mid-October). It looks straight across Frenchman Bay toward the hills of Mount Desert Island, which means the island's view without the island's crowd. It's the kind of place you go for a slow afternoon by the water rather than a checklist. For how the tide shapes the shore here, see tides & the shore.

Hancock — Tidal Falls, and the mainland's hidden coast

East across the head of Frenchman Bay, Hancock is the quieter mainland answer to the island. Its standout is Tidal Falls Preserve — a free 8-acre Frenchman Bay Conservancy preserve about 25 minutes from the house, built around a reversing tidal falls on the Taunton River. When the tide turns, the current runs backward through the narrows; from the observation deck and picnic tables you can watch the water change its mind and, more often than not, spot seals hauled out on the ledges, plus osprey, eagles and herons working the rich water. It's free to visit; note that dogs aren't allowed because of the picnic area. It's the same living-tide phenomenon our own shore runs on — more on that in tides & the shore.

Winter Harbor & the Schoodic Peninsula — Acadia without the crowds

Round the far side of Frenchman Bay — about 42 minutes from the house, and no bridge to cross — and you reach Winter Harbor, the small town at the gateway to the Schoodic Peninsula. Schoodic is the one piece of Acadia National Park that sits on the mainland: the same pink granite pounded by the same surf as Mount Desert Island, with a fraction of the people. If the island feels busy, this is the day that fixes it. We wrote it up in full in the journal: Schoodic — Acadia without the crowds.

Farther afield

West and south of Ellsworth, the Blue Hill peninsula unwinds toward the sea, and it's second-visit territory: half-day-plus loops rather than errands. Blue Hill has galleries, pottery studios, and a summer chamber-music tradition. Castine keeps its Revolutionary-era streets and its maritime history close. And Deer Isle and Stonington, at the very end of the road, are granite country with a working lobster fleet — one of the prettiest working harbors in Maine.

The through-line

Put together, these towns are the argument for staying where you're staying. You sleep on a quiet cliffside on Union River Bay, provision in Ellsworth, cross to the island early for the marquee days in Acadia and Bar Harbor — and on the slow days you never cross the bridge at all: Lamoine, Hancock, and Schoodic are all yours on the mainland side.
