Walk up to the preserve entrance off Walker Street, near Lakeshore Drive, and the first thing you see is a sign that says no dogs allowed. The second thing you see, on any weekday morning, is a dozen people walking dogs past it without a second glance.
Both things are true at once, and that contradiction is the whole story. Nassau County posted those signs years ago. In 2015, the county opened a specific stretch of this same preserve to on-leash dogs after years of advocacy from LI-DOG. The signs still reflect the earlier policy. What that means for anyone who lives near the Peter J. Schmitt Massapequa Preserve is that the real rule depends on exactly where you are standing, not on what the nearest sign tells you.
The Preserve Is Two Trails Wearing One Name
Most people who drive past the preserve on Sunrise Highway or Merrick Road think of it as a single wooded stretch. It is actually built around two parallel routes that run the length of the property and behave nothing alike.
On the paved side runs the Bethpage Bikeway, a smooth multi-use path connecting the preserve to Bethpage State Park and running further out toward Syosset and Farmingdale. It draws cyclists, runners, rollerbladers, and skateboarders in enough volume that dogs, leashed or not, are prohibited on it. The pavement and the speed of the traffic on it are exactly why.
Running roughly parallel on the unpaved side is the Nassau-Suffolk Greenbelt Trail, a dirt and packed-earth path that connects into the Fire Road Trail near the Walker Street entrance. This is the side where leashed dogs are permitted, and it is also the longest hiking trail in Nassau County, continuing well beyond the preserve itself toward Cold Spring Harbor.
So the preserve is not one trail with one rule. It is two trails, on two surfaces, with two different answers to the same question.
| Trail | Surface | Dogs | Typical entrance |
|---|---|---|---|
| Bethpage Bikeway | Paved | Not permitted | Preserve access points along Sunrise Highway and near the train station lot |
| Fire Road Trail | Unpaved dirt | Leashed dogs permitted | Walker Street, near Lakeshore Drive |
| Nassau-Suffolk Greenbelt Trail | Unpaved | Leashed dogs permitted | Merrick Road and Ocean Avenue |
What 2015 Actually Settled
The on-leash opening did not happen because the county changed its mind about dogs in general. It happened because LI-DOG spent years asking Nassau County for more legal places to walk a dog, and the Fire Road Trail became the pilot. The county's own language at the time described it as a trial period, tied specifically to that stretch of dirt path off Walker Street, not to the preserve as a whole and not to the paved bikeway running alongside it.
That distinction is the part that gets lost. A decade later, current pet-travel listings for the preserve still describe the same split: leashed dogs welcome on the unpaved Greenbelt side, off limits on the paved bikeway. In several spots, signs still read as they did before the 2015 change, so a "no dogs" sign may stand over a trail where dogs have been legally permitted, on leash, for years.
If you already walk a dog here, none of this may surprise you. If you are new to the neighborhood and taking the sign at its word, you may be avoiding a trail you are actually allowed to use, or assuming you are allowed to skip the leash somewhere it still matters. Both mistakes are easy to make when the posted rule and the actual rule disagree.
Finding the Right Entrance
The preserve runs roughly four miles from Merrick Road up toward the South Farmingdale line, broken into sections by the roads that cross it. That length is part of why first-time visitors get turned around, and it is also why a Massapequa High School student named Trevor Kapuvari, working with Troop 660, led a scouting project to install detailed trail maps at three entrances: Ocean Avenue and Merrick Road, Brady Park, and Mansfield Park. Those framed maps mark the paved trails, the foot trails, the lakes and streams, and the entry and exit points, and they remain the clearest on-site reference for anyone trying to figure out which fork leads where.
For dog owners specifically, the Walker Street entrance near Lakeshore Drive is the most direct route onto the Fire Road Trail, with a dirt lot for parking and poop bag stations along the path. If you are coming from the Merrick Road or Ocean Avenue side, you will land on the Greenbelt Trail portion, which also permits leashed dogs but keeps you further from the paved bikeway traffic. Either way, the rule of thumb that actually holds up is simple: dirt path, leash is fine; pavement, leave the dog at home.
The Trail Changes With the Season, Not Just the Rules
September and October are when the unpaved sections of the preserve are at their best for walking. The canopy along the Greenbelt Trail turns color before most of the rest of the neighborhood does, and the ground firms up after summer's muddier stretches, at least until the leaves start piling up and holding moisture again later in the fall.
The reservoir gets its own seasonal rhythm. Massapequa Lake is stocked with trout every spring and fall, and Nassau County allows a daily limit of five trout year round for anyone fishing with the proper license, a detail that brings out a steady stream of anglers along the water's edge right around the same weeks the leaves are turning. If you are walking the Greenbelt side in the coming weeks, expect to share the path with more rod cases than usual.
None of this requires a permit to enjoy as a walker. The preserve is free and open year round, and the paved lots near the entrances fill up fastest on weekend mornings, which is when the bikeway traffic is heaviest anyway. If your goal is a quiet walk with a leashed dog, a weekday morning on the Fire Road or Greenbelt side remains the easiest way to get it.
The Short Version
The sign at the entrance reflects the preserve's earlier dog policy. The current rules distinguish between the paved Bethpage Bikeway and the unpaved trails. The paved Bethpage Bikeway stays off limits to dogs because of the volume and speed of bike and skate traffic it carries. The unpaved Fire Road and Greenbelt Trail permit leashed dogs, and current listings still confirm that distinction. Knowing which side of that line you are standing on is the difference between a wasted trip and 423 acres of dirt trail, right in the middle of town, that you already have full legal access to.
If you are settling into Massapequa and still learning which of its everyday details actually match the paperwork, that is the kind of local knowledge worth having before you need it for something bigger, like a home.
