All the information you need for planning your trip to Muir Woods.
Muir Woods is open 365 days a year, 8:00 a.m. - 6:00 p.m
The coast redwood forest is cool most times of the year with temperatures ranging from 40 - 70 degrees F or 4 - 21 degrees C. From late October to early May expect rain. Summer months (June-August) can be warmer but it is generally cool and dry. Expect heavy fog in the morning, burning off in the afternoon. Some say fall (August-October) is the best weather of the year. But, don't let the weather stop you from having fun. If you're dressed for the weather and wear sturdy shoes, the giant trees are beautiful all year round.
In addition to the $15 entrance fee to Muir Woods, you will need to pay $9 per vehicle if you choose to park in the Muir Woods parking lot. To park at Muir Woods you need to make an online reservation in advance. There's no cell phone service or Wi-Fi at Muir Woods National Monument, so you will need to download your parking reservation before arriving to the park. Please be aware that booking a parking spot doesn’t mean there will be a spot available for you when you arrive at the park, it simply means once a spot opens up you are permitted to park there.
If you choose to take the public Muir Woods Shuttle offered by the park, instead of driving, there will be an additional $3 charge. You will need to book this ticket online in advance as well.
