They have a great running trail with workout equipment along the way and a great park, picnic area and open space. While visiting NJ this weekend I took my dog here. He loved the opportunity to burn off some energy and play ball. The only complaint about this park which hasn't changed much is all the goose poop! Other than that, I will continue to bring my dog here when I visit and take the occasional run on the trail.

The trail even leads to the backside of Twin Rivers. A lot of people enjoy fishing at Etra Lake which is a decent sized lake adjacent to the park. There's three parking areas: one adjacent to the lake, one near the fields, and another large parking lot across the street. During non-Covid times, they usually host the East Windsor Fourth of July fireworks every summer and there's fun entertainment and food vendors. Overall a nice place to enjoy the outdoors!

There is a portapotty (if you're into that sorta thing). It's a beautiful spot to unwind or let the kids release some energy.

It's a great place to bring lunch and eat under the gazebo by the lake. Lovely!

There are even a small number of campsites that can be reserved during certain times of the year. There are also large playing fields that host tournaments throughout the year for baseball, soccer, lacrosse, etc., and rowing regattas are hosted on the lake. At 3.9 square miles, Mercer County Park is a whopping 1.7% of the total acreage in all of Mercer County. The NE portion of the park is part that I like best, as it's also the part that gets the least amount of traffic, with the only folks you see being people walking the trails, birdwatchers and BMX bike riders. I wouldn't advise taking a gravel bike on the paths in this part of the park. I used to come here often with my bike, but now I'm also enjoying the trails on foot. If you're a road bike owner who's just looking for a short ride, the paved paths that run the length of the park, and the broad shoulder of the main road offer a good conditions for a road bike, but you'll need to look elsewhere for a longer, challenging ride. Also, I've yet to encounter the entitled dog owners who think that the leash regulations don't apply to them. I'm sure that they're out there, but perhaps they're not as common as they are at places like Mercer Meadows or Mountain Lakes--fingers crossed.

Easily my favorite trail in the New Jersey area! Breathtaking views on both sides with canals and…read morerivers. Spectacular choice for fall foliage viewing! This is my hands-down winner for the best trail in New Jersey, I've hiked it, and I have biked it! I love all of the other trails in New Jersey, but this one rises to the top for a few reasons. Often there is water on both sides of the trail. There's a man-made canal on one side and sometimes either a river or a lake on the other side. Plus, it's lush with trees and vegetation. Also, the trail is really great if you wanna go biking. You can't go wrong wherever you decide to explore. I would recommend biking since it's such a beautiful trail and you'd want to see as much as you can. Also, the trail is very flat and easy to ride. It's not paved, but it is a wonderful easy riding surface without dust. I recommend parking either at Kingston, which is my favorite. Or at Rocky Hill. You could also park in Princeton along Washington Street near the kayak rental place. If you park at the Kingston trailhead, if you turn one way and head towards Rocky Hill you will see the most breathtaking views I feel the trail has to offer with majestic Streams and canals with cliffs and trees, and all directions. If you take this trail in the fall, you will be blown away by nature! If you ride in the other direction from Kingston towards the Princeton trailhead, you will pass a long and beautiful lake on your right hand side with beautiful views and trees on your left! If you love trails, this one put to the top of your list if you live in New Jersey or nearby Princeton! Super highly recommended! Going in October during the fall can be a transcending experience!

There are over 70 miles of paths/trails along the D&R canal, passing through many historic towns…read moreand landmarks in NJ with some pretty houses along the way, from near Frenchtown down to Trenton, then up to New Brunswick, in a V shape. The D&R runs parallel to the Delaware & Lehigh (D&L) trail on the Pennsylvania side, so you're also getting a view of the Delaware River on that part of the track. The trail is mostly flat and is suitable for walking or biking. We love riding this trail and exploring sections of it at a time and the surrounding towns. Some sections are more scenic than others. A favorite easy ride (or hike) of ours is to start in Lambertville NJ, ride up to Stockton, cross over Center Bridge to the PA side, grab a burger at Dilly's, then ride down to New Hope, PA, walk around town, and return to Lambertville via the New Hope-Lambertville Bridge. It's only about 8 miles roundtrip and makes for a leisurely day, and is very doable even for kids.

To get there you need to make a left turn off Eldridge (check out a map). There are also unmarked trails for those interested in hiking or mountain biking.

Perrineville Lake Park is perfect for this type of outing. Leashed dogs are allowed on all the trails and on this trip we took the pretty Lakeside Loop trail around the lake through fields and woods.

NJ truly has beautiful parks for all abilities and bringing your dog along will make it that much more special.
