Lynn Woods

Lynn Woods Reservation with your dog: leash rules, trails and parking

Lynn Woods has been a city park since 1881, and three city bodies share it: the Park Commission, the Department of Public Works and the Lynn Water and Sewer Commission, with one full-time park ranger running it day to day. That last partner explains why the dog rules read the way they do. This page covers the rule, the trails that suit a leashed dog, parking, and the hazards to plan around, all checked against the city's own pages in fall 2026.

The rule

Lynn's restraint ordinance runs through the whole reservation, and the reservoirs are off limits

The City of Lynn's Park Rules Manual, linked from the Parks and Recreation rules page, states that the city ordinance for restraining dogs is in effect throughout Lynn Woods. The city's animal control page spells that ordinance out: no owner may let a dog run at large at any time, and a dog must be kept indoors, inside a safely enclosed yard or on a leash. A forest trail is neither a house nor a fenced yard, so in practice the rule is a leash from the moment the car door opens until it closes again.

The manual adds rules written for this forest. Owners must remove dog waste from trails, roads and parking lots. Pets are prohibited from entering in or upon the reservoirs, because Walden's Pond, Breeds Pond and Birch Pond supply Lynn's drinking water and sit under the Water and Sewer Commission; people may not swim, boat or fish in them either. Neither the manual nor the Lynn Woods page names an off-leash area inside the reservation. The animal control page lists the city's dog park separately, on Parkland Avenue near Richardson Road.

  • Lynn's dog restraint ordinance applies everywhere in the reservation
  • Waste comes out with you from trails, roads and parking lots
  • No dogs in or on Walden's Pond, Breeds Pond or Birch Pond
  • Open sunrise to sunset and closed at night

Trails

Fire roads give a leashed dog room; the foot-traffic trails give it quiet

More than 30 miles of trail cross the reservation, and the city's rules sort them for you. Official trails carry a colored paint blaze and appear on the city map, and the manual's own test is simple: if a trail is not on the map, it is not an official trail. Horses may use only the orange-blazed fire roads. Bikes must keep to marked trails and stay off any trail signed for foot traffic only, and mountain biking is not allowed at all in winter.

For a dog on a leash, those rules point to two kinds of walk. The wide orange-blazed fire roads give you room to step aside for a horse or a runner, which suits a young dog still learning to pass people calmly. The foot-traffic trails keep bikes away, which suits a dog that lunges at wheels. The city's manual warns that footing is difficult in places and the ground hilly, so a senior or a short-legged dog may be happier sticking to the fire roads.

Dungeon Rock is where many first visits end up. The city describes it as an underground tunnel with a long history of pirate lore and treasure hunters, but the pages we checked give no visiting hours and no separate dog rule for it. Ask the park ranger before you plan a walk around the tunnel. If your dog dislikes echoes or tight spaces, let one adult wait outside with the dog while the other goes in.

Parking and timing

Park at Pennybrook Road or Great Woods Road and plan to leave before sunset

The city lists two main entrances with parking, Pennybrook Road and Great Woods Road. The park ranger works from the Lynn Woods Park Headquarters at the Pennybrook Road entrance, and the manual gives the ranger's number as (781) 844-0363 and tells groups to check with the ranger for seasonal updates and closures. Events, tours and programs are posted on the bulletin boards at both entrances. None of the city pages we checked mention a parking fee.

The reservation closes at night, so a late-afternoon walk in November has far less daylight in it than the same walk in June. The woods are also used heavily for team and individual races, mostly on the dirt roads and trails, and each event needs Park Commission approval. A dog that is unsettled by a crowd of runners will have an easier first visit on a weekday morning, once you have read the board at the gate.

Hazards

Ticks are the main hazard here; hunting is not, because the city bans it

Lynn Woods is one of the North Shore forests where hunting is not a worry: the city's manual prohibits it outright for conservation reasons, along with fires and grills, camping, paintball, and ATVs and dirt bikes. That makes October to December a calmer time to walk here than at reservations that run a bow season. Ticks are the hazard that does apply. The CDC says ticks live in grassy, brushy and wooded areas and are most active from April to September, although exposure can happen in any month.

Carry water for your dog, because the reservoirs are not a drinking stop and the rule keeps dogs out of them. Run your hands over the coat, the ears, the armpits and between the toes before the drive home, and ask your veterinarian which tick preventive suits your dog. A dog that comes back caked in trail dust after a long loop can have a bath at Dogtown with no evaluation, from $55 for a dog up to 25 pounds.

  • No hunting in Lynn Woods, unlike several reservations nearby
  • Ticks are most active April to September, per the CDC
  • Bring water, since the reservoirs are off limits
  • A bath after the woods starts at $55, with no evaluation

From Lynn

Lynn is outside the Pup Van towns, so a daycare day starts with the drive to Gloucester

Dogtown is at 210 Eastern Ave in Gloucester, a short way along Eastern Avenue from the end of Route 128. Lynn is outside the four Pup Van towns of Rockport, Gloucester, Essex and Manchester-by-the-Sea, so ask us about pick-up. Daycare is $42 for a full day and $33 for a half day, in playgroups of 7 to 10 dogs matched by size and temperament, and from Lynn a full day usually makes better use of the drive than a half.

Every daycare, Academy, overnight-stay and walking client starts with a free evaluation on a weekday between 6:30 and 9:30 AM, with Rabies, DHPP and Bordetella records and a current city dog license on file. Lynn licenses renew on April 1 each year through the City Clerk at City Hall, Room 201. Our Lynn page in the service areas section covers the rest of the trip, from the drive up to the first playgroup.

Asked and answered

Questions people ask about this

Short, complete answers you can act on today. More in the full FAQ.

Do dogs have to be on a leash in Lynn Woods?
Yes, in practice. The city's park rules apply Lynn's dog restraint ordinance throughout the reservation, and that ordinance allows a dog off your property only on a leash, since otherwise it must be indoors or in a securely fenced yard. Neither the Park Rules Manual nor the Lynn Woods page names an off-leash area inside the woods. Check the bulletin boards at the entrances for anything newer.
Can my dog swim in the ponds at Lynn Woods?
No. Walden's Pond, Breeds Pond and Birch Pond are reservoirs for Lynn's drinking water, and the city's rules prohibit pets from entering in or upon them. People are barred from swimming, boating and fishing there for the same reason. Carry water for your dog, and if you want a dog swim, choose a place whose manager allows it in writing.
Where do I park for Lynn Woods with a dog?
Use one of the two main entrances, Pennybrook Road or Great Woods Road, which the city lists as having parking. The park headquarters and the ranger are at the Pennybrook Road entrance. The city pages we checked in fall 2026 do not mention a parking fee. The reservation closes at night, so arrive with enough daylight for the loop you plan.
Can I take my dog to Dungeon Rock?
The city describes Dungeon Rock as an underground tunnel but does not publish visiting hours or a separate dog rule for it on the pages we checked. The reservation-wide rules still apply, so your dog stays leashed. Call the Lynn Woods park ranger at the number in the city's manual before you build a walk around the tunnel, and leave a nervous dog outside with a second adult.
Is there hunting in Lynn Woods?
No. The city's Park Rules Manual prohibits hunting in Lynn Woods for conservation reasons, so a fall walk there does not overlap with a hunting season the way a walk at some Trustees reservations does. Ticks are still around into the fall, and the CDC notes that exposure can happen year-round, so check your dog after every visit.
