Explore the Cobb Estate in Altadena, CA

The Cobb Estate in Altadena, CA is a beloved urban-wildland gateway offering scenic hikes, local history, and a hint of ?haunted forest? lore at the top of Lake Avenue.


History and Legacy

Originally the private grounds of lumber magnate Charles Cobb in the early 20th century, the estate once featured a grand mansion, gardens, and ornate stonework.

Although the residence was later removed, remnants like stairs, foundations, and the iconic iron gate still frame the entrance and inspire the nickname ?the Enchanted (or Haunted) Forest.?

Community advocates and the Sierra Club helped preserve the property as open space, ensuring public access and protecting native habitat on the Altadena foothills.


Hiking and Nature

Today the Cobb Estate serves as a key trailhead for the Sam Merrill Trail, leading hikers to Echo Mountain and Inspiration Point with sweeping views of the San Gabriel Valley and downtown Los Angeles.

Expect chaparral, oak and sycamore groves, spring wildflowers, birdsong, and occasional wildlife as the route climbs into the Angeles National Forest.

The wide initial paths make it family- and dog-friendly (leashes required), and golden-hour light creates especially photogenic scenery.


Visitor Tips

Park along Lake Avenue near the gated entrance, arrive early on weekends, and be courteous to nearby residents when parking or visiting at dawn or dusk.

Trails can be steep, sunny, and seasonally hot, so bring plenty of water, wear sturdy shoes, and watch for loose rock and rattlesnakes.

For a low-impact visit, follow Leave No Trace, stay on marked routes, and enjoy the blend of history, ruins, and nature that makes the Cobb Estate one of Altadena?s signature outdoor destinations.
