Want to visit a Texas State park on total solar eclipse day? Here's what you need to know.

Texas Parks and Wildlife Department will release park day passes in just a few weeks for April 8, when a total solar eclipse will pass over Texas.

A total solar eclipse is when the moon passes in front of the sun, blocking its light. The eclipse is expected to pass over the Austin area around 1:35 p.m. But you don't have to be in Austin if you want to view the eclipse — the eclipse's path includes 31 state parks and natural areas, according to TPWD.

Day pass reservations open on March 8 at 8 a.m. and can be made online or by calling: 512-389-8900. Day pass reservations for Enchanted Rock State Natural Area open on March 11 and must be made over the phone. Camping reservations opened in November and slots at Austin-area state parks McKinney Falls, Pedernales Falls and Enchanted Rock are all sold out. Day passes will likely sell out swiftly.

McKinney Falls State Park is within the eclipse's path of totality.

For day passes, two reservations can be made per account. Two day pass reservations would be for two vehicles and include everyone in the vehicles. Reservations will be available for multiple entry times beginning at 6:30 a.m.

Fees for passes vary by park, but if you have a Texas State Park Pass, the fees will be waived.

Even if you have a Texas State Park Pass, you must make a reservation for eclipse day.
