Tucked within Topanga Canyon is the coolest hike that you have likely never even heard of. (No, it's not on AllTrails!) -- Introducing the Topanga Time Tunnel Hike!

A storm drain? You bet! But, not just any storm drain! Follow this tunnel, and you will be led to a beautiful grotto hidden away on the other side. It really does feel like you crossed to another world!

We recommend parking along Topanga Canyon Road (Pay attention to the signage, and do not block the roadway (e.g. do not park over the white line!)) -- Roadside parking is free!
It's recommended to use Jalan Jalan Imports as the meeting point to start this hike.
The trail entrance is located at 1636 S. Topanga Canyon Road (west side of road), and is located 20 feet down past the Slippery When Wet road sign.

Sure, it looks pretty ominous, but what great adventure doesn't start out that way? The tunnel appears steeper than it actually is -- you can easily walk through upright, using your hands to help navigate the tunnel.

Welcome, Time Traveler-- you have arrived! At the bottom of the tunnel, you will proceed by turning to the right. The trail contains a lot of three-to-four foot boulders that involve a decent amount of rock scrambling. We recommend wearing shoes with good grip that you don't mind getting wet.

Continue straight along this trail (total trail length ~2 miles), and you will find more fun surprises -- log crossings, waterfalls, swimholes and sometimes even fish!

This is one of my favorite spots in LA and I love sharing this adventure with others -- it's probably one of the most exciting and surprising hikes you can find.

I highly recommend stopping by in the summer months -- The photo below was taken in late July of 2020 -- the water was crystal clear, swimmable and extremely refreshing. We even saw plenty of fish! Absolutely worth the visit. (I will warn that in winter/early spring the water may not be so clear-- it really depends; I would plan to return again in the summer).






This hidden Los Angeles hike sounds like a refreshing alternative to the trails that dominate every weekend list. I especially appreciated the practical details and the sense that the route still offers a little discovery. When I record trail notes or ambient sounds to share afterward, MP3 Size Reducer helps keep those audio files manageable. Thanks for highlighting a local outing that feels adventurous without requiring a trip far outside the city.
This hike sounds amazing, especially the idea of discovering a hidden place through something as ordinary as a storm drain. Speaking of unique ways to enjoy free time, I also like trying quick games like Rocket Goal when I’m relaxing, and it’s a fun little break after reading about cool adventures like this.
I visited a similar spot in early spring and was a little disappointed by the murky water, so your summer recommendation makes a lot of sense. Exploring clear water and spotting fish feels as rewarding as finally mastering a tricky track in PolyTrack !
I realized quickly that timing matters more than speed in Subway Surfers City especially with the Hoverboard Energy System. Choosing when to activate your board adds a layer of strategy I didn’t expect from a runner game.
Whether that’s hidden trails or discovering something unexpected on sites like Cool Games. In both cases, the fun comes from stumbling onto something unique that most people haven’t discovered yet.
