Consider it your free national parks pass: On Saturday, Sept. 28, all national parks across the nation will be free to enter, including popular California destinations like Muir Woods, Yosemite and Joshua Tree.

To celebrate National Public Lands Day — the largest single-day volunteer effort in the U.S. — every Park Service site that usually charges an entrance fee will offer free admission to all visitors, as part of NPS’ Free Day program. (Remember: after Saturday, there’s only one more free National Parks Day coming up in 2019, on Nov. 11 for Veterans Day.)

To mark the occasion, we asked you for your tips on visiting the wealth of national parks within a day's drive from the Bay Area. Whether you're planning on visiting Saturday or at another time, scroll down for our audience's advice.

"Be mindful of the signs and rules. They are there for your safety. I’ve seen too many people disregard them and end up hurt. If it says 'don’t go here with your bike,' don’t go there with your bike!" (@annmariechristy, via Twitter)

“Want great photos of old growth redwoods? Lady Bird Johnson Grove [in Redwood National and State Parks] is the place you want to go, a short 1.5 mile loop that can take you hours if you like to take photos.” (@SCCDP, via Twitter)
