Felix Neck Wildlife Sanctuary

Do some birding! Felix Neck has a good assortment of different habitats– woods, fields, ponds, marsh, etc. so you feel like you are actually in nature. It’s not all that big, though. Walking the perimeter trails only takes about an hour. They offer kayak trips that look like they’d be fun.
You can rent binoculars and go on an expedition.
Hints:
You can bike or take the bus to Felix Neck. Bikes can be left at the visitors center lot (they are not allowed in the trails). To take the bus, take the Vineyard Haven/​Edgartown bus and get off at the entry road. Walk ¾ mile to the visitors center. It sounds tedious but it’s actually a very pretty walk. Keep an eye on the return schedule.

I’ve done the Felix Neck walk a few times — it’s a perfect family walk (at least for my family) because there’s enough walking for those among us who are walkers, without overwhelming those in my family who aren’t walkers. I’d say I spend about an hour at Felix Neck and can cover all of the trails with plenty of stops for checking out the view of Sengekontacket Pond. One warning though — to echo Adam R — Felix Neck has TONS of mosquitoes, and you should absolutely use bug spray before heading down any trails here, or else you will be eaten alive.

WARNING: DO NOT VISIT WITHOUT DOUSING YOURSELF IN COPIOUS INSECT REPELLENT! The pleasant notices, sweetly semi-​rural dirt road and inviting arrival at Felix Neck Wildlife Sanctuary in retrospect now remind me of a one of those alluring flowers or horror flicks which attract visitors to their doom. The elder volunteer at the front desk mentioned that the paths had been cleared of underbrush, so no worry about ticks. But, she didn’t in any way adequately warn us about the swarms of ravenous, vicious, bloodthirsty mosquitoes and flies. They sell insect repellent at the visitors’ center, which was a hint, as well.
Once we were well into the walk, as the mosquitoes began mounting on our legs, necks, and arms, we hoped emerging from the woods onto the sunny shore would relieve us. It only got worse. We ended up on a forced, bloody, sweaty half-​run the last mile of the journey, continuously swatting away never ending waves of blood sucking misery, smearing the blood on our hats, shirts, and skin. We certainly got our Martha’s Vineyard nature lesson for the day, and no need to worry about Jaws to get shivvers. A shame we couldn’t actually enjoy the gorgeous views or 90% of our time there, except perhaps in rueful retrospect for «I can’t BELIEVE THAT!!» humor.

Felix Neck is one of the many cool little places on the Vineyard that never seems to be crowded. A great place to get away from the tsunami of summer tourists.
It’s only about 350 acres but located right on Sengekontacket Pond. The ocean is just over a narrow spit of land called Beach Road and Joseph Sylvia Park. Another very cool place.
Forget about bringing a mountain bike, no bikes or dogs are allowed, just hiking. Lots of cool looking Cormorants and Ospreys love this place and if you are lucky you will see one sweep down and pull a large fish out of the water.
You start at the Visitor’s Center that has some maps, books and displays and then hike on one of the 6 or so trails. The main trail is called the Jessica Hancock Trail and takes about an hour to finish. Great water views on all sides and lots of indigenous flora is everywhere.
Last time I was there this old guy told me a story that Jessica still walks the path evern though she is long gone. I guess she loved this place so much she still can be seen on certain nights in her night grown and hair blowing in the wind. I’ve her similar stories on Block Island and Nantucket, and Island places seem to love such stories. Even though I’ve never seen Jessica, Felix Neck is still a very cool place.
