This National Monument was created in 1908 named after famous conservationist John Muir. Muir was quoted as saying “It’s the best tree lovers monument that could possibly be found in all the forests of the world”.
To visit Muir Woods, you must make a parking space or shuttle reservation before you leave. There's no cellphone reception or WIFI there.

You can shorten this trail to an easy 1/2 mile loop walk if you cross earlier at Bridge 2. Alternatively it's only a 1-mile loop walk if you cross at Bridge 3. These shorter routes have the advantage of being hardscape all the way.
5. Peer up at giant redwoods.
Muir Woods National Park
Their average age of these redwoods is an astounding 500 to 700 years old! There were once 2-million acres of the beauties in the Western United States, now reduced to almost nothing.
6. Discover a redwood's age, by looking at a cross-section of its rings.
Key events are marked on each ring of this cross-section of tree, like 1492 when Columbus arrived in America, or the 1776 Declaration of Independence. This tree dates back to 909AD making it over 1,100 years old!
7. Search for Coho or Steelhead Salmon in the creek.

The highlight of Muir Woods is ethereal Cathedral Grove, where the largest and oldest trees are found. The dense coastal fog has enabled these redwood giants to reach 250 feet in height. The oldest tree is dated 781 years old (as of 2019). Walk under the canopy and experience the majesty of this primal forest.
