Best Places to View the Moon in Portland, Maine
Portland sits at roughly 43.66°N on Casco Bay in southern Maine, the state's largest city with around 70,000 residents and the seat of Cumberland County. Built across a series of hills and peninsulas overlooking a bay dotted with islands, the city carries an old maritime signal tower on one hilltop and one of the country's most photographed lighthouses just down the coast. Between the hills, the harbor, and a short ferry ride out into the bay, Portland gives a genuinely coastal set of places to watch the moon.
Eastern Promenade & Munjoy Hill
A large waterfront park along the top of Munjoy Hill, giving sweeping views out over Casco Bay and its islands. Captain Lemuel Moody built the Portland Observatory here in 1807 as a commercial communication station, using telescopes and signal flags to alert subscribing merchants when their ships were approaching Portland Harbor — now a National Historic Landmark and the only remaining historic maritime signal station in the United States.
Portland Head Light & Fort Williams Park
One of the oldest lighthouses in the United States, completed in 1791 and widely considered among the most photographed in the country, standing in nearby Cape Elizabeth. The surrounding Fort Williams Park adds shoreline trails and old coastal defense batteries to the setting, giving an open Atlantic horizon that can frame a moonrise over the water when the timing lines up.
Western Promenade
A park in Portland's West End, on the opposite side of the peninsula from the Eastern Promenade, with views inland toward the surrounding hills and mountains rather than out over the bay. Its Victorian-era streets give the walk here a different, more architectural character than the harborfront.
Old Port
The city's historic waterfront district, with cobblestone streets and 19th-century brick warehouses now home to shops, restaurants, and fishing piers. It's Portland's easiest option for an ordinary evening, with opportunities to frame the moon over the working harbor when its rising position lines up.
Casco Bay Islands
A cluster of islands reachable by Casco Bay Lines ferries, including Peaks Island and Great Diamond Island. Service runs year-round, with schedules changing considerably by season. A short ferry ride out gives a genuinely different vantage point over the water than anything on the mainland.
Back Cove Trail
A roughly 3.5-mile loop trail circling a tidal inlet just north of downtown, popular with walkers and runners. Its flat, open path can give a low, easy sightline over the water without needing to leave the peninsula.

While Actually There
Portland's whole layout is built around watching the water. The Portland Observatory went up in 1807 for exactly that purpose — Captain Lemuel Moody needed a way to spot approaching ships from Munjoy Hill so subscribing merchants could learn when their vessels were nearing harbor, and the tower he built is now the only one of its kind surviving in the country. Portland Head Light, just down the coast, has been serving as a navigational aid even longer, in place since 1791.
The rest of the city fills in around those two points. The Eastern and Western Promenades face in different directions from their respective hills — one out toward the bay and its islands, the other inland toward the surrounding hills — giving the city genuinely different characters depending on which way you're looking. A ferry ride out to the islands changes the perspective again, putting the mainland itself into the view instead of just the water.
None of it requires much beyond checking the current ferry schedule if you want to visit the islands, since sailing times shift considerably by season. The Old Port, the promenades, and Back Cove Trail are all straightforward for an ordinary evening without much advance planning.
"Portland built a tower on one hill to watch for ships, and a lighthouse down the coast to guide them home — the whole city has been looking out at this water for a very long time."
Your Portland Moon Chase Checklist
Before You Go
- Check the moonrise time and phase on this page for each night of your stay
- Check the current Casco Bay Lines schedule if you want to visit the islands — service runs year-round but sailing times vary considerably by season
- Check current opening hours for the Portland Observatory if you want to climb it, not just view it from outside
- Check current hours for Portland Head Light's museum if you want to go inside, since the grounds and lighthouse exterior are separate from museum access
- Check the forecast for coastal fog or storms, which can roll in quickly along this stretch of coast
What to Bring
- Serious winter clothing for December–February — Maine coastal winters bring regular sub-freezing nights
- A tripod, useful at open spots like Fort Williams Park and the Eastern Promenade
- A windproof layer for any waterfront spot, since wind off the bay is a near-constant factor
- Comfortable shoes for the walk up Munjoy Hill and around Back Cove Trail
- Spare camera batteries kept warm in an inner pocket during cold-weather sessions
On the Night
- Arrive 20–30 minutes before moonrise at open spots like Fort Williams Park or Back Cove Trail
- Shoot RAW and bracket exposures, especially where Portland Head Light mixes with moonlight
- Mind wind and cold at every exposed coastal spot, particularly in winter
- Confirm your return ferry time in advance if visiting the Casco Bay islands in the evening
- Watch for coastal fog, which can appear with little warning and obscure the sky entirely
Portland Moon Phase — Frequently Asked Questions
Q. What is the moon phase today in Portland?
The moon phase today in Portland is a New Moon with 0% illumination. The next full moon is in 17 days, on Oct 26. Moonrise is at 5:45 AM and moonset at 5:33 PM.
Q. Where is the best place to view the moon in Portland?
The Eastern Promenade, a large waterfront park along the top of Munjoy Hill, gives sweeping views out over Casco Bay and its islands, with the Portland Observatory nearby. Fort Williams Park in Cape Elizabeth, home to Portland Head Light, adds shoreline trails and an open Atlantic horizon that can frame a moonrise over the water. The Old Port is the easiest option for an ordinary evening with the working harbor in front, and the Back Cove Trail, a loop of about 3.5 miles around a tidal inlet, gives a low, easy sightline over the water. The Western Promenade faces inland toward the hills, and the Casco Bay islands give a different vantage point by ferry.
Q. Where does the moon rise and set in Portland, and how high does it climb?
At about 43.7°N, Portland's moonrise and moonset points swing across the horizon each month, from roughly northeast to southeast for rising and northwest to southwest for setting. A winter full moon culminates high in the south, at roughly 70° above the horizon, while a summer full moon stays low, peaking near 23°. Portland sits on a peninsula in Casco Bay with the Atlantic to the east and southeast, so the Eastern Promenade and Fort Williams Park look out toward the rising moon over the bay or open ocean. The Western Promenade faces inland toward the hills, the direction of moonset, so it suits a setting moon rather than a rising one. Check the azimuth for your date and exact spot.
Q. Is light pollution a problem for moon observing in Portland?
The moon is bright enough to observe and photograph from almost anywhere in Portland, so light pollution rarely limits the lunar disc itself. It does wash out earthshine on a thin crescent and any faint sky detail. The Old Port, the working harbor and the promenades carry substantial artificial lighting, so central Portland is a light-polluted site rather than a dark-sky one, best suited to moon-over-water and moon-over-city compositions. Portland Head Light adds its own illumination at Fort Williams Park.
Q. What camera settings and phases work best for moon photography in Portland?
For a full moon, start with Looney 11 (f/11, ISO 100, 1/100 s) and refine using your histogram, since it is a baseline rather than a guarantee. The moon is much brighter than the harbor and lighthouse foreground, so shoot RAW and bracket or blend exposures to keep both crater detail and the lit foreground. A full moon rises around sunset over the bay, and a waxing moon sets over the hills to the west in the evening. A 200–400 mm lens helps isolate the moon against Portland Head Light or the Portland Observatory's silhouette, with a tripod for bracketing and manual focus on the moon using magnified live view.
Q. How do coastal fog, wind and winter cold affect moon viewing in Portland?
Coastal fog or storms can roll in quickly along this stretch of coast and obscure the sky entirely with little warning. Wind off the bay is a near-constant factor at exposed coastal spots like Fort Williams Park and the Eastern Promenade, so a windproof layer and sturdy tripod help. Winters bring regular sub-freezing nights, occasional snow and the region's longest nights, and cold drains camera batteries quickly, so carry a spare and keep it in an inner pocket. Check the forecast for fog, wind and storms before heading out.
Q. Can I shoot the moon at Portland's viewpoints after dark?
Access varies by site. Casco Bay Lines runs year-round, but sailing times change considerably by season, so check the current schedule and confirm your return ferry time if you plan an evening island visit. Check current opening hours for the Portland Observatory if you want to climb it, and for Portland Head Light's museum, since the grounds and lighthouse exterior are separate from museum access. The Eastern and Western Promenades, the Old Port and the Back Cove Trail are open outdoor urban spaces.
