The Emerald Necklace With a Dog: Olmsted's Chain, and What It Costs You

Eight parks, roughly six miles, free throughout, and open to a leashed dog everywhere except the botanical garden at the downtown end.

Frederick Law Olmsted designed a chain of connected parks across Boston in the late nineteenth century. It runs from the edge of downtown out to Roxbury, and almost all of it is open to a leashed dog for nothing.

That makes it the best-value dog walking in the city by a wide margin. It also has one hard exclusion at the downtown end and one park in the middle that plays by different rules.

The chain, and where dogs stand

Park	Neighbourhood	Dogs
Boston Common	Downtown	leashed, plus a rotating off-leash parcel
Public Garden	Downtown	not permitted at all
Commonwealth Avenue Mall	Back Bay	leashed
Back Bay Fens	Fenway / Kenmore	leashed
The Riverway	Fenway / Kenmore	leashed
Jamaica Pond	Jamaica Plain	leashed
Arnold Arboretum	Jamaica Plain	leashed at all times, its own rules
Franklin Park	Roxbury	leashed, facilities under study

The leash limit across parks under the Parks and Recreation Commission is eight feet, from Section 3 of the parks regulations. The Public Garden exclusion is in the same section.

The one you have to walk around

Start with the exclusion, because it sits at the front of the chain and it will otherwise ruin a perfectly planned route.

The Public Garden bars animals. Section 3 of the parks regulations says no person shall:

"have or allow any animal, including a cat or dog, with the exception of a seeing eye dog for a blind or handicapped person, on a leash, within the boundaries of the Public Garden"

This is not a leash rule with a loophole. It is a presence rule. So if you are walking the Necklace from the downtown end, the route is: Boston Common, then up Charles Street or Beacon Street rather than through the Garden, then pick the Necklace back up at Commonwealth Avenue Mall.

The Garden's own city page explains why without ever mentioning dogs. It was "the first public botanical garden in America", "decorative and flowery from its inception", and the Parks Department still grows every plant used in its bedding displays in city greenhouses, cultivating over 80 species. It is a horticultural collection that happens to look like a park.

Boston Common, the generous end

The Common is the opposite. Founded in 1634 and described by the city as "America's oldest park", it has absorbed grazing cattle, a British encampment, victory gardens and four centuries of public assembly. It is not precious, and the dog rules reflect that.

Leashed dogs anywhere on it, up to eight feet. And a rotating off-leash parcel run as the Common Canine programme by a sub-group of the Friends of the Public Garden, approved by the Parks Commission in 2013.

The published rules for that parcel: hours of 6 A.M. to 11 P.M. except during special events, a maximum of three dogs per adult at any one time, under-18s accompanied by an adult, current vaccinations and licence, an owner ID tag worn at all times, the dog leashed entering and exiting, and the handler carrying a leash while inside.

Finding it means reading signs. The programme says: "Please follow the rules and refer to posted signage on Boston Common for locations of approved areas."

Address: 139 Tremont Street.

Commonwealth Avenue Mall, the connector nobody rates

A linear green strip running west from the Public Garden through Back Bay. The city's own description notes the Mall's 32 acres were part of the designed landscape.

For a dog it is close to ideal and almost never described that way. It is long, it is straight, it has trees, it is flanked by traffic on both sides but separated from it, and it takes you from downtown to the Fens without a decision to make. On a cold February evening when you want a mile of walking and nothing else, this is the answer.

Eight-foot leash, and read any posted signage. City page here.

The Fens and the Riverway, the quiet middle

The Back Bay Fens and the Riverway are the two stretches of the Necklace that most visitors never walk, and the city describes the Riverway as providing "scenic relief" for the corridor it runs through.

These are the parts of the chain that feel least like a city. Winding water, mature planting, and paths that curve enough that you lose the traffic noise for stretches. The eight-foot leash rule applies, children's areas are excluded, and there is no off-leash provision.

One honest note: these are also the least-lit and least-populated stretches, and the parks regulation bars anyone from being in a park between 11:30 p.m. and 6:00 a.m. except to pass through on the walks. Judge accordingly for an evening walk in winter, when Boston is dark by half four.

Jamaica Pond, the one with water you cannot use

Jamaica Pond is a kettlehole left by a glacier, and the city's description of it is worth quoting because it explains the appeal:

"The pond plunged to more than 50 feet in depth, a kettlehole formed by an ancient glacier. Natural springs make it the largest and purest body of water in Boston."

Olmsted, per the city, thought it needed almost nothing done to it: he described wanting "a natural sheet of water with quiet graceful shores" and mostly preserved the existing vegetation, adding tree groupings, shrubs and pathways to frame it.

The loop path around the pond is one of the best dog walks in Boston. Established 1891, 507 Jamaicaway, boathouse on 857-452-1770 with boats for rent in summer and a note that private boats are not allowed.

The catch for dogs: the parks regulations bar bathing and swimming in parks under the Commission's control. So the largest and purest body of water in Boston is a walk, not a swim. If your dog is a swimmer, this is the park where you will have to be firm about it.

The Arnold Arboretum, which is a park and also not

This is the most interesting jurisdiction in the chain, and the Arboretum's own visitor page explains it in one sentence:

"Since the Arboretum is a public park of the City of Boston, we must comply with their regulations."

It is a Harvard institution and a living museum of plants, and it is simultaneously a Boston park. So Boston's rules apply, and the Arboretum layers its own on top.

The dog rule, verbatim:

"Dogs must be leashed at all times. Owners are responsible for removal and disposal of their dogs' waste."

Leashed at all times, with no off-leash exception anywhere on the property, which is a stricter reading than the city's own general regulation implies.

Other Arboretum rules a dog walker should know:

Rule	Detail
Plant material	picking, collecting or destroying is strictly prohibited
Plant beds	walking in beds or mulched areas is not allowed
Picnics, fires, barbecues	prohibited
Organised group sports	prohibited
Smoking	prohibited on the property
Bicycles	paved paths and the Blackwell Footpath only, 10 mph or slower
Cost	its banner says "Open every day. Free every day."

Practical detail. Restrooms are at the Hunnewell Building, 125 Arborway, 10am to 4pm daily. Arboretum Ambassadors are in the landscape during daytime hours, 7:00am to 5:30pm, and can be reached on 857-268-3185. In an emergency, the entrances they name for access are the Arborway Gate at 125 Arborway, the Flora Way Gate and the Peters Hill Gate.

And the warning that matters most for dogs. The Arboretum tells visitors ticks are often found in natural areas like it, and gives a direct instruction: "When you get home, conduct a full-body tick check on yourself, children, and pets." That is a spring-to-autumn habit, not an optional one. Stay on trails, walk in the centre of them, and check the dog in the car park before you drive home.

Franklin Park, the biggest and the most likely to change

Franklin Park is the anchor of the Necklace and, in the city's words, "The 485-acre park remains Boston's largest open space." Olmsted designed it in the 1890s, it sits at the geographical centre of the city, and it connects Roxbury, Dorchester, Jamaica Plain, Mattapan and Roslindale.

The city calls it Boston's "country park", and lists miles of trails, playing fields, the historic Bear Cages, Scarboro Pond, the William Devine Golf Course, a cross-country running course, the Franklin Park Zoo, White Stadium, the Elma Lewis Playstead and multiple playgrounds. Address is 1 Franklin Park Road.

For a dog today it is a leashed walk with a great deal of ground to cover, and the usual exclusions: no children's areas, and the playing fields are on that list.

What may be coming. The city has an open Franklin Park Dog Facility Study, whose stated purpose is:

"In response to community input during the Franklin Park Action Plan process, we're conducting this study to scope and locate dog facilities within Franklin Park."

What is on the table, in the page's own words: "formal dog parks", "off leash dog areas", "site furnishings related to dog care such as dog bowls", and "dog bag dispensers". The consultant is Kyle Zick Landscape Architecture, and the city is working with Neighborhood Services and the Franklin Park Coalition.

Given that Boston currently has five fenced off-leash spaces and one rotating parcel, an off-leash area inside a 485-acre park would be the most significant addition to the city's dog map in years. The page lists community meeting dates without a year while its own events panel says there are none scheduled, so we are not printing a date. Check the page and email the contact listed on it if you want to be heard.

What the whole chain costs

Nothing. Not one park in the Necklace charges admission for a walk, the Arboretum says so on its banner, and no off-leash fee is published anywhere in Boston.

The cost is in the rules: eight-foot leash, bags, no children's areas, no swimming, and a botanical garden you walk around rather than through.

A day that uses the chain properly

Morning, downtown. Boston Common, look for the off-leash signage, twenty minutes loose if the parcel is convenient.

Then west. Up Charles Street, avoiding the Garden, onto Commonwealth Avenue Mall for a straight mile.

Midday, the Fens. Slower, quieter, more sniffing.

Afternoon, Jamaica Pond. The loop, and a firm hand about the water.

Late afternoon, the Arboretum. If you have the legs. Free, open every day, leashed throughout, and the best planting in the city. Tick check in the car park.

That is most of a Necklace, roughly six miles of it, all legal and all free. Bring water, because none of these parks publish a dog fountain network, and our summer heat safety notes matter in August on the paved stretches.

If you are basing a trip around this, the Jamaica Plain and Fenway ends put you closest to the best of it. Our Boston hotel directory and the pet-friendly hotels in Boston list cover the options, and what to pack for a hotel stay covers the towel you will want after the Fens in March.
