"Sorry to say there's no really good ""legal"" way to get there from here. There's a bike path that runs along the Wantagh that will get you to Jones Beach. Taking Ocean Drive east from there would get you to the Robert Moses Causeway Bridge. Problem is -- no bikes allowed on Ocean Drive or the RM Causway and the State Police are out there. This is really wrong, but that's the deal.

I often ride out to Bayshore on the Montauk highway (27a) and take the ferry. Problem there is what to do with your bike -- they won't let you take it on the ferry. Since I have a place to stay out there, I have at times put it on the freight boat for delivery the next day. To get home, I ride out to Robert Moses Lot 5 and have my wife meet me there with the car. What a world...

I have actually ridden to/from the bridge to the lighthouse on my little one speed bike for exercise -- but typically on the grass at the side of the road and have feigned ignorance when stopped (probably not the best policy). the other issue, should you get past the police, is that from the lighthouse to kismet you are dealing with a veritable sandpit through which you will basically have to carry your bike for a mile or so.

I am quite surprised that fire island ferries doesn't allow bikes on the regular ferry -- even if paying some nominal fee. they certainly allow some quite big bags.

The FI ferries will only take bikes on their freight boats. I've ridden out on a Sunday and had my bike brought over the next day; done the opposite returning.
Once.

FI is no place to ride a bike nor bring a quality one. It's all sand and salt. A road bike is useless, a fat tire bike will allow you to ride, (East to West)from Dunewood through Fair Harbor, Saltaire and Kismet onto the Ocean Highway where riding on the grass shoulder is ok. There are sand pits between Saltair and Kismet and Kismet and the Ocean highway. Beware of herds of deer in these spots at night. And kids, toddlers, pedestrians, etc.. get the picture?

West of Dunewood is deep sand and Ocean Beach where riding a bike will get you a ticket.

A northern route out that works is any route out to Cold Spring or Syosset, then Rt108, Avery, Washington, Old Bethpage, Half Hollow, to the Vanderbilt Motor Hwy to Wicks to Fifth Ave in Bayshore. I think the ferries are on 4th. Wolf Hill looks interesting as an alternative to get to the Vanderbilt (on a map). This was 10 years ago and nothing stays the same.

The above applies to Bayshore, never been east of there.

If you must ride call OB ferries and ask if they could store your bike in their freight house. (you'll pay) Just make sure you return when it's open and you can get it.

"Fire Island Ferries' policy as stated on a conspicuously placed sign at the Ocean Beach Terminal in Bay Shore -- NO BIKES NO WAY!"""
