Mariton Wildlife Sanctuary

This is about as back in the alley as it gets in terms of wanting to be one with nature or in terms of wanting to find somewhere really quiet where you can be alone to think where unlike at certain PA state parks, chances are that here you’ll never see anyone because at least in our visits, no one is ever here (I only saw two other cars over three different visits both weekday and weekend).
The backbone of the sanctuary are the walking trails. None of them are difficult in terms of length as most of them individually are less than a half mile. But, what gets you is the incline as some of the trails have inclines that are Billy Goat steep especially the River Outlook Trail and the South Fox Trail. Everything is clearly marked with wooden markers that have colored tops letting you know which trail you are plus some limited signage.
For me a nice walk is to simply go straight out the Chimney Rock Trail and once you get to the end you are (a good number of trees are present) treated to a decent view of the Delaware River, a little sliver of 611 and River Road in NJ.
I think that Tom B. said it best when he said that the charm of coming here is that it seems like they made the sanctuary just for you because even though you’re fairly close to Easton proper, it’s very quiet, never crowded, the trails are fairly short which makes everything feel very personal.
If you go:
The sanctuary is open everyday from sunrise to sunset. The parking lot is not large but based on the amount of usage this place sees it doesn’t have to be. While it’s called a wildlife sanctuary I can’t say that I’ve seen much in terms of wildlife. Some birds and a few chipmunks although their website and blog show pictures of some deer and fox. Mostly it’s a lot of trees and various native grasses/​wildflowers. They do have rest rooms on site which have been open each time we’ve been there but their nature center is open ?? as their website says it’s by chance or by appointment.
Last tip would also be what Tom B. said regarding trespassing. When you turn onto Sunnyside road and see the no outlet sign and the narrow road you’ll swear that you’ve gone the wrong way or that it can’t be right but keep going because it is and it’s worth a visit.

FIrst to review gave a really accurate account. Went here on whim because I’d never been here… and quite honestly, quite a few others I speak with never have either. People here are REALLY friendly who have ties to the place, they opened up the barn just for us it seemed and we looked around. Trails have some that are wide open, and others can be narrow and steep. Good mix for both.
You can get a good elevated view of the Delaware River, and truly feel like you are desolate, even though Easton is not far, and rt 611 is right next to you.
I like it here and would go back for sure. Good choice of easier paths for a quick walk or intermediate for those that want a more rustic hike. I’ve been here twice… and it NEVER seems crowded. Kind of like they made the park just for you.
NOTE: you will think you are trespassing because of the lack of people… but that is the place.

This is a beautiful 200-​acre park in the middle of nowhere created to protect wildlife and provide and educational opportunity and a few miles of trails for visitors.
There is a small visitors center in a barn on the property which displays information on animals, trees and plants around the sanctuary.
The trails can be a little difficult due to elevation. There are trails that access overlooks for the Delaware River, a rock formation called Chimney Rock, a fern garden and more. Trails are marked by color and by sign when two trails meet. You can download a trail map from their website or obtain one at the information kiosk.
I didn’t spend much time here because it was 90+ degrees and high humidity but I was amazed at the beauty of this park. It’s also free access but I am sure they would graciously accept a kind donation.
