The 6 hour, 10.5 mile Bridge to Nowhere hike in the San Gabriel Mountains is one those hikes that you have to do at least once in your life. As the name suggests, you hike along the San Gabriel River in the beautiful Sheep Mountain Wilderness for about 5 miles, and then, out of nowhere, there’s a huge, 120-foot high bridge! The hike is fun, especially on a hot summer day, because there are plenty of stream crossings and water holes to cool off in. It’s a classic Southern California hike that every local knows about, and is worth doing at least once.

What is the Bridge to Nowhere??

To start, this Bridge to Nowhere is not one of those tax boondoggles that you read about in the news. The Bridge to Nowhere was supposed to go somewhere. In 1929 work started on the East Fork Road, which was going to connect San Gabriel Valley with Wrightwood to the north.  The bridge was a vital link on that road and was built in 1936. But only two years later, in 1938, catastrophic flooding in the San Gabriel River washed the road away, leaving only, well, you guessed it, a Bridge to Nowhere.

Then in the 1950s, when everyone was in the grips of Cold War nuclear holocaust paranoia, the government thought it would be a good idea to build a highway through the San Gabriel mountains to evacuate people from LA to the Mojave Desert. The abandoned Bridge to Nowhere was to be used in this new evacuation route. Work started on the new route, Shoemaker Canyon Road, in 1956, done mainly by prison inmates, hence the local nickname of “Convict Road.” The progress was slow, and only 5 miles of the proposed 25 mile road was finished by the time work was abandoned in 1969, leaving the appropriately named “Highway to Nowhere.” The highway never made it to the bridge, but you can still check it out on the drive (to or back from) the bridge hike.

Bridge to Nowhere Bungee Jumping

The Bridge to Nowhere is also home to Southern California’s only commercially licensed bungee jumping option. The bungee jumping has been around since 1989 (the oldest in the USA), and the attraction has been featured in tons of movies, commercials, and even has some world records. For $99 you can hurl yourself off the Bridge to Nowhere into the abyss.

You might be asking yourself, “how is there a commercial bungee jumping operation in the middle of the Sheep Mountain Wilderness?” Well, the owner of the bungee jumping operation bought the land from private owners who owned the land as a gold mining claim. It turns out that the bridge was built in the claim area. The bungee jumping operation has a bit of controversy around it, and people have been trying to shut it down for years.

Love it or hate it, it’s there. Here’s what you need to know as a hiker:

If you’d like to bungee jump, you can make reservations and learn more at the Bungee America website. I’ve never done it, but folks like Arnold Schwarzenegger and Jim Carey have, so you’ll be in good company.

When to Do the Hike

You can pretty much do this hike any time of the year, but there are a few things to watch out for.

If there have been heavy rains in Southern California and/or it’s winter, the San Gabriel River can be flooded. You have to cross the river a few times, and the water can be up to your waist and portions of the trail covered. This is not a very fun experience, I would do the hike another day.

If there’s any chance of thunderstorms or heavy rain on your hike day, there can be flash floods, and you’ll want to postpone. People have died in flash foods here, and you need to take it seriously.

There’s also no shade on the hike, so if you go on a hot day, it can get pretty brutal. Luckily you can dip into the water and cool off, but it can still be pretty brutal. Leaving at sunrise is a good bet to avoid the heat, crowds, and overflowing parking lot. And if you have dogs, make sure they’re good in heat as well.

Gear for the Hike

Feet In San Gabriel River
You will get wet on this hike. You can try and jump across rocks to stay dry, but why? Embrace the water on this hike.

I’ve seen people do this hike with flip flops, a 12oz water bottle, and a bluetooth speaker. Don’t do this. Here’s what I would recommend.

How to Get to the Bridge to Nowhere

The Bridge to Nowhere hike trailhead is about 30 minutes north of downtown Azuza, CA. The drive is spectacular and winds its way on the side of San Gabriel Canyon, with the river and reservoirs below. The overlooks are worth stopping at to soak in the views.

You can use this trailhead address: Bridge to Nowhere Trailhead, Camp Bonita Rd, La Verne, CA 91750.

Can I drive to the Bridge to Nowhere??

Not without hiking the last 5 miles.

Parking for the Bridge to Nowhere

Fee Area Parking At Bridge To Nowhere Trail
You need a permit to park for the Bridge to Nowhere trail.

The parking lot for the Bridge to Nowhere is a fee area, and you need to buy a pass before you arrive at the trailhead. You can use a National Parks Pass (which I highly recommend if you hike a lot) or an Adventure Pass, and display it in your window. People do get tickets here for not having passes and for parking in “no parking” zones.

If there’s no parking left in the lot, you can park down on the side of the road. Some areas of the road are marked with “no parking” signs, so avoid those, but otherwise it’s open game. I’ve seen cars parked for miles along the road. Do yourself a favor and get there by sunrise at the latest, or go on a weekday.

Overflow Parking At Bridge To Nowhere
It’s about 11am, and people are parked along the road, about a mile from the trailhead.

Map Downloads For The Hike

I usually hike with a combination of a paper map and digital map. You can print the PDF map below, and you can also print this web page out. There’s also a GPX file that you can use on GPS devices.

garmin fenix 5xI use the Garmin Fenix 5x mapping GPS watch for my maps and navigation, which works great. It tracks my hikes, all my workouts, my sleep, heart rate, and a ton of other functions. It’s a little pricey, but I literally use it every day to monitor my health, workouts, and adventures. I’d recommend checking it out. You can checkout all of the navigation and mapping gear I use here.

Hike Elevation

Bridge To Nowhere Elevation

Many guides note that there’s about 800 feet of elevation change, which is kind of accurate. There’s actually about 800 feet of elevation difference between the start and finish. But there’s more like 1900 feet of total climbing when you factor in all the ups and downs on the trail. Overall it feels generally flat with a few short, steep uphill sections, but add in all the undulations and it can be more fatiguing than you’d think.

This hike in the middle of the mountains avoids any major climbs by making it’s way up the valley. It’s still a tough one though.

Once you climb the rocks, the trail continues straight. Avoid the side trails down to the river and continue straight and upstream.
Bridge To Nowhere Trail
You’ll go through this wash area. The trail splits apart and comes back together quite a bit, and this happens in other places as well. Try to take the path most worn, and again, if the trail peters out, turn around, retrace your steps to the last split, and try another way.

It’s easy to miss unless you know what you’re looking for.
East Fork Trail

Bridge To Nowhere Bungee Jumping
I got here early when they were setting up the bungee jumping (on the right). They’ve designated an area for hikers to safely pass on the left. Again, you might not enjoy that this is here, but please be respectful of the area and business. Also, notice that the bridge is lower on the right side. Why? I have no idea.
San Gabriel River Gorge
Check out the gorge from the top of the bridge. The swimming holes are down there.
Trails Around Bridge To Nowhere
Continue over the bridge and down the trail for views of the bridge and to climb down to the watering holes. The trail can be loose and steep here, be careful. You can also continue on the upper ridge to an abandoned tunnel. Some folks camp tbere.

Grab your pictures of the bridge, and then continue back the way you came. if you get here early, you might even see some bighorn sheep on the hills above you.

After you’re done with the bridge, simply head back the way you came.  And again, pay attention as you go, it’s easy to take a wrong turn if you’re motoring ahead on autopilot.

A quick note. These directions are meant as a guide for the hike, and not a definitive source. Conditions change, and the information here can be different based on time of day, weather, season, etc. There can be small side trails that you might see but I missed. I have made every effort to include all the information you need to complete the hike successfully. I recommend using this guide in conjunction with a map, GPX file, common sense, and call to the ranger station or park office. If you do the hike and notice something has changed, please contact me and I will update the guide.
