Location: Centerport, NY

Size: 43 acres

Date of hike: July 1, 2026

The Suffolk County Vanderbilt Museum and Planetarium has a hilly one-mile loop path that features educational signs about the planets called the Solar System Hiking Trail.  I learned about the picturesque trail during a recent visit to the planetarium with my wife and our two-year-old son Everett, who loves everything involving outer space.  Unfortunately, he was too young to tackle the advanced path, so I went back a few weeks later by myself.  Needless to say, I’m happy I did, because the trail was out of this world!

Before exploring, I briefly researched the history and habitats of the Solar System Hiking Trail, which includes a scale model of the solar system and traverses the rolling woods located adjacent to the Charles and Helen Reichert Planetarium.  The trail itself, which was “one of the first Long Island hiking trails,” dates back to the 1920s when William K. Vanderbilt II created it while living in his 24-room Spanish-Revival mansion on the 43-acre waterfront summer estate known as Eagle’s Nest in Centerport, according to the estate’s website.  “Eventually, the trail became overgrown and disappeared into the forest,” the website said.  “The Suffolk County Vanderbilt Museum, located at Eagle’s Nest, has reclaimed the hiking trail and held a grand opening on November 19, 2023.  Major project donors and museum trustees attended the event in the rose garden, which is also the trailhead.”  Apparently, the path also compliments programs offered by the planetarium on the topics of astronomy and science, technology, education and math – also known as STEM.

The estate’s entrance is on Little Neck Road just north of Cobblestone Court, with the trailhead located a stone’s throw north of the planetarium building.  To reach the trailhead, I walked past the planetarium until I reached a beautiful fountain and followed a grassy staircase down a steep hill where the trail began at an opening in the forest off to the right.  “This is an advanced hiking trail with many steep climbs and descents,” the estate’s website said.  “It is cleared and free from overgrowth.  However, the dirt trail features some loose terrain and an elevation gain of nearly 300 feet.”  For inexperienced hikers, there are two opportunities to cut the hike short and return to the parking lot if you or your party cannot finish the loop, according to the website.  General admission is $15 for adults, $12 for seniors, and $10 for children under 12.

The hike’s highlight for me was the educational signs throughout the trail that provided interesting details on the solar system.  “This hiking trail scales down distances to the planets in our solar system, starting with the sun and ending up at Neptune,” stated a sign at the trailhead.  “Along your hike, you will start from the sun and pass by each of the planets so that you can see how far they are from each other, and how large they are at this scale.”  Other signs compared the objects in our solar system to various household items – such as a beach ball for the sun, a pebble for Earth, and a golf ball for Saturn.  “The sun is our closest star,” another sign said.  “It gives us the light we see, the heat we feel, and without it there would be no life in Earth.  It is…so big that you could fit 1 million Earths inside.”

Regarding wildlife, the trail had everything from eagles to white-tailed deer.  The eagle was proudly perched atop an abandoned structure I encountered near the second opportunity to turn back to the parking lot.  Instead of turning back, I turned right toward the structure and instantly spotted the eagle standing atop almost as if he was guarding it.  The building seemed to be a boarded-up boathouse with breathtaking views of Northport Harbor.  It was the perfect spot on the perfect day.  I also saw a fawn shortly thereafter when I heard some rustling in the woods.

All in all, I definitely recommend that all hikers check out the Solar System Hiking Trail while visiting the Suffolk County Vanderbilt Museum and Planetarium.  While the walk can be challenging at times, the signs make it fun and the views make it all worthwhile.  And, of course, don’t forget to catch a planetarium show while you’re there to learn even more about the planets!
