Salisbury Beach State Reservation Wildlife Guide
Beach, river mouth and marsh: where to start
The ocean beach, river shore and salt marsh offer different views. From the beach, scan beyond the surf for diving birds. From the river shore, look across the exposed rocks for seals. To the west, the marsh, pines and open ground hold different groups of birds. Use public paths and viewpoints rather than crossing dunes or marsh grass.
Enter the reservation from Beach Road and follow State Reservation Road south to the southernmost parking lot beside the jetty. Seacoast Science Center uses this lot for its Salisbury seal walks and describes about half a mile (0.8 km) of walking down to the shore. That is the organized walk description, not a marked loop: allow time for the return and follow any access restrictions.
Quick visit facts
Wildlife viewing areas at Salisbury Beach
| Area | Best for | What to expect | Best season |
|---|---|---|---|
| River mouth at the southern end of the reservation | Harbor seals, gulls, purple sandpipers, sea ducks | Around low tide, scan the exposed river rocks for seals. At higher water, watch the remaining rocks for resting birds. Stay on stable ground ashore. | Fall through spring |
| Open beach and surf line | Loons, grebes, sea ducks, migrant shorebirds | Scan the ocean beyond the breakers. Calm water makes diving birds easier to follow between dives. | All year, strongest in cooler months |
| Salt marsh edge | Herons, shorebirds, waterfowl, raptors and owls | Look across the marsh from open paths and parking-area edges. Do not enter the marsh or approach resting owls. | Spring, fall and winter |
| Campground and pine edge | Open-country winter birds and migrant songbirds | Check open ground and pine edges where access is permitted. Winter birds include horned larks, snow buntings and sparrows; crossbills occur irregularly. | Late fall through early spring |
Where and when to see harbor seals
DCR and Essex Coastal Scenic Byway describe harbor seals here in fall and winter. Look across the Merrimack River for groups resting on exposed rocks around low tide. Binoculars help because the seals may be well out from shore. Their position can change as the water rises.
Choose a daylight low tide, then check wind and surf conditions. If the rocks are empty, look for seals surfacing in the river or spend the visit watching birds. Do not cross wet rocks or enter the water to reach a closer viewpoint.
Seacoast Science Center asks viewers to stay at least 150 feet (about 46 meters) away. Move farther back if a seal reacts to your presence. Resting on land is normal; do not try to send it back into the water.
Birds on the ocean and jetty
Sea ducks, loons and grebes
Common eiders and scoters use the ocean and river in colder months, along with loons and grebes. Keep watching after a bird dives so you can see it again at the surface. A distant silhouette alone may not be enough to identify the species.
Gulls and purple sandpipers
Look for purple sandpipers and gulls resting or feeding on rocks. Higher water can concentrate birds on the remaining exposed surfaces. A spotting scope helps you inspect a roost without moving closer.
Herons, waterfowl, raptors and owls
Look along marsh creeks for herons and migrating shorebirds in spring and fall. Waterfowl use the marsh through the colder months, when raptors may also hunt over the grass. View any resting owl from a distance; do not search through roosting cover.
Salt marsh, pines and open ground
The marsh lies west of the beach. Stop at an open public viewpoint and check creek banks, exposed mud and grass edges. Look carefully before moving: individual birds may stand still in vegetation rather than gather in an obvious flock.
Where access is permitted, check open ground near the campground for horned larks, snow buntings and sparrows in winter. Pines can hold migrating songbirds, while crossbills appear irregularly. Look from designated routes, keep out of occupied campsites and follow closures.
Salisbury Beach through the year
Spring
Watch marsh edges for returning herons and migrating shorebirds. Some sea ducks remain early in the season. Use open access points and stay outside any marked nesting areas.
Summer
Visit early to avoid the busiest beach hours. Check the shoreline and marsh for birds, keep away from nesting enclosures and leave feeding birds room to use the beach. Do not plan a summer visit around a winter seal gathering.
Fall
Migration brings changes on the beach, in the marsh and around the pines. As colder weather arrives, spend more time scanning the ocean and river for sea ducks and checking exposed rocks for seals.
Winter
Focus on seals, eiders, scoters and other open-water birds. Scan the jetty from shore for roosting birds. Dress for wind, allow for ice or snow on access paths and check which facilities are open.
Two ways to plan a first visit
A short seal-watching visit
- Follow State Reservation Road to the southernmost parking lot near the river mouth.
- Set aside about an hour for walking and viewing; allow longer if sand, mobility or weather slows the return.
- From an open shoreline viewpoint, scan exposed river rocks around low tide.
- Turn back the way you came; do not extend the walk onto the jetty rocks.
A longer visit for seals and birds
- Start with the river view if low tide coincides with safe weather and daylight.
- Scan the ocean from an open beach access for sea ducks, loons and grebes.
- Add a marsh-edge or campground-edge stop where access is permitted.
- Leave time to return without rushing over wet sand, ice or uneven ground.
What to check before leaving
- A local tide prediction for the Merrimack River mouth, not an unrelated beach.
- Wind, visibility and surf conditions, even when the tide is low.
- Current park access, parking information and restroom availability.
- Binoculars, warm layers, sturdy footwear and drinking water.
Safety and wildlife etiquette
For seals
- Stay at least 150 feet from seals and increase the distance if they react.
- Keep dogs away. Do not touch, feed, cover or pour water on a seal.
- Do not force a seal into the water; report concerns to Marine Mammal Rescue.
For the jetty
- Do not climb wet or icy jetty rocks for a closer photograph.
- Watch from stable shore-side ground, clear of breaking waves and surging water.
- Turn back when weather or footing makes the viewpoint unsafe.
For the marsh side
- Check seasonal hunting rules and posted notices.
- Do not cut across sensitive marsh edges or dunes.
- Use designated boardwalks and open beach entrances.
Found a seal on shore?
A resting seal does not automatically need rescue. Keep people and pets back and do not touch, feed, cover or move it.

Frequently asked questions
Where can I see seals at Salisbury Beach?
Start at the southern end of Salisbury Beach State Reservation near the Merrimack River mouth. From an open shore-side viewpoint, scan exposed rocks in the river. Keep at least 150 feet from seals and do not climb onto the jetty to approach them.
What is the best time to look for seals?
Plan for fall or winter around a daylight low tide, when more rocks are exposed. Seals may still be absent. Check wind and surf before deciding whether to visit.
What birds should I look for?
In fall and winter, scan the water for eiders, scoters, loons and grebes, and the jetty rocks for gulls and purple sandpipers. In spring and fall, also check the marsh for herons and migrating shorebirds.
Can I watch wildlife without a long hike?
Yes. Some views are available from parking areas and boardwalks. Reaching the shore may involve soft sand, ice or uneven ground. Check the surface before going farther and allow time to return.
Is Salisbury Beach worth visiting in winter?
Winter is a good season for harbor seals and sea ducks. Bring windproof layers and binoculars, check current access and avoid icy paths, jetty rocks and wave-exposed areas.
Who do I call about a seal on the beach?
Call Seacoast Science Center Marine Mammal Rescue at 603-997-9448. Watch from at least 150 feet away, keep dogs away and do not touch, move, feed, cover or pour water on the animal.
