Hurricane Evacuee Camping
Governor Abbott opens Texas state parks to hurricane evacuees.
Hurricane Harvey evacuees can stay for free in Texas state parks. Please call parks to check availability.
Some parks in coastal and south Texas regions are closed due to the hurricane. Parks not listed here may have limited availability; if you are an evacuee and you are near a TPWD park that is not listed here, you can check this map to see if the park is open.
