Questions people ask

Can I bring my dog or bike?

What should I watch out for in summer?
Mosquitoes and flies can be thick in spring and summer, so bring bug spray. Poison ivy and ticks grow throughout the refuge: staying on the trails limits your exposure.Source: U.S. Fish and Wildlife Service, Wertheim NWR: Visit Us ↗ (opens in a new tab)
Can I get there without a car?
Yes. The Long Island Rail Road's Montauk Branch stops at Mastic-Shirley, about a mile east of the visitor center, and Suffolk County Transit buses 66 and 68 run on Montauk Highway, about a mile north.Source: U.S. Fish and Wildlife Service, Wertheim NWR: Visit Us ↗ (opens in a new tab)
