Some residents headed to the beach Saturday after Isaias, but many parks on Long Island still don't have power.

Parks officials say state beaches across Long Island are now open and safe for swimming. Jones Beach reopened Thursday after the storm.

But, like many parks, the power is still out. State park officials say one of the biggest impacts of the loss of power at Jones Beach is that the bathrooms are closed and not working right now.

They brought in port-a-potties and stationed them along the beach for beachgoers to use.

The Town of Oyster Bay tells News 12 all of its beaches are back open too.

Most of the state parks are open, with the exceptions of Wildwood, Caleb Smith and Valley Stream, which are still closed due to power outages, uprooted trees and low-hanging branches.

Robert Moses, Sunken Meadow and Jones Beach are all welcoming visitors.

Officials say more than 400 trees have been uprooted at state parks on the Island.

Crews from bigger parks like Jones Beach are being deployed to ones that are closed to help them reopen faster.
