Welcome to the Signal Hill Letterbox Hybrid!
This cache combines GPS navigation with classic letterbox-style clues. Please read all directions carefully before heading out.
Parking:
Park at the coordinates listed on the cache page:
N 33° 47.832 W 118° 09.242
Important: No parking Mondays between 4:00 AM – 8:00 AM due to street sweeping. Plan accordingly to avoid a ticket.
Trailhead Waypoint:
Before you can begin following the letterbox clues, you must use your GPS to find the trailhead at:
N 33° 47.830 W 118° 09.368
(A waypoint is provided in the listing for this location.)
This is your required starting point for the clue-based portion of the journey.
Clue-Based Directions (Starting from the Parking Area):
From the parking coordinates, begin walking towards the trail. Start heading uphill—you're about halfway up the hill, not at the top yet.
The hill is steep but short—only about 528 feet—so take your time as needed.
When you reach a nature trail, this marks the beginning of your route.
Turn right onto the trail and continue walking until you see a yellow fire hydrant.
Stick to the sidewalk on the right-hand side. When the walkway changes to paving stones (those brick-like tiles), turn right.
You’ll come to a set of stairs—head down.
At the bottom, walk to the corner of the fence. Look for a metal T-post with studs—that’s your final destination!
Need a hint? A spoiler photo is provided to help you verify the final location if you get stuck.
