Off the radar of most hikers, the Exploration Trail to Keller Peak is a scenic adventure that’s not too hard but also packs in some great trail highlights. The entire area you hike through was devastated by the 1970 Bear Fire; today, as you hike, you can experience what a half-century of recovery looks like (it’s good). Along the way, you’ll get some epic views of the Angeles National Forest and the surrounding high peaks. At Keller Peak, you can experience the oldest standing fire tower in Southern California, dating back to 1926.

Where is the Exploration Trail?

The Exploration Trail is point-to-point and has two trailheads. We’re going to start this hike at the lower trailhead and then hike uphill to Keller Peak. You can find the quiet trailhead just off of busy Rt-18, past the Deer Lick Fire Station at:
Exploration Trail 2W09X, Keller Peak Rd, Big Bear, CA 92314

There’s a small parking area at the trailhead. While it’s small, I’ve never seen big crowds here. The trail starts to the right of the parking area.

I’ve also seen people parking across the street on the shoulder.

There are no bathrooms or water fills at the trailhead.

Gear For the Hike

While this isn’t an extreme mountain hike, you are still in the high country and I recommend regular hiking gear.

Garmin Inreach Mini 2

Garmin InReach Mini 2
I’m a firm believer in carrying a satellite communications device which works where cell phones don’t. I use a Garmin InReach which lets me send text messages back and forth to my family to let them know that I’m okay or if my plans change when I’m out in the backcountry. It also has an SOS subscription built-in so that you can reach first-responders in an emergency. The devices also offer weather reports, GPS, and navigation functionality (what’s the difference between a GPS and satellite communicator?). For a few hundred bucks they could save your life, so for me it’s a no brainer to have something like a Garmin InReach. If you use a smartphone to navigate and want a more affordable option that integrates with your phone easily, check out the ZOLEO.

Lone Peak 6 Yellow

Altra Lone Peak 6
For most people, the Altra Lone Peak is a solid choice that will leave your feet feeling great at the end of any hike. The feel is cushy and light, and if it had a car equivalent, this would be a Cadillac or Mercedes Sedan. The grip is great and they’re reasonably durable for this type of trail runner, which I think is better in most conditions than a hiking boot, and here’s why. The downside of this shoe is that it won’t last as long as something like the Terraventure 3 or Moab 2 (see alternate footwear choices at the bottom of my gear page). I’ve been using mine for many miles and my feet always feel great. I have a video on the details of the Altra Lone Peak 6 here.

Black Diamond Ergo Poles 2

Black Diamond Trail Ergo Cork Trekking Poles
I’ve gone back and forth on trekking poles, but I think for most people they are a good investment. They help you dig in on the uphills, provide stability on loose downhills, act as a brace when crossing streams, and can probably poke away aggressive wildlife in a pinch. The Trail Ergo Cork poles are a good balance of light weight, durability, affordability, and ease of use. If you want something ultralight and a little more pricey, I’ve had great luck with the Black Diamond Z Poles too.

Gregory Zulu 30

Gregory Zulu 30 & Jade 28
After testing quite a few backpacks, the Gregory Zulu 30 (and Jade 28 for women) is, for most hikers, the best all-season day-pack. First off, it’s very comfortable, and the mesh “trampoline” back keeps your back dry. Its 30L capacity is enough for all the essentials and plenty of layers for winter hiking. External pockets make it easy to grab gear. It’s hard to find something wrong with the pack; if anything, it could be a bit lighter, but overall, it’s not heavy. And its price-point makes it not only affordable but generally a great value.

Trail Maps

The section of the hike on the Exploration Trail is a gradual uphill dirt trail. Keep your eyes and ears open for mountain bikes that share the trail. You’ll have a short but very scenic walk up paved Keller Peak Rd to reach the summit and fire tower when the Exploration Trail ends.

How Are You Going to Navigate This Hike?
Here’s what I use. If you are a hardcore hiker and/or hike in extreme conditions, I recommend getting a dedicated GPS like a GPSMAP 66sr or 66i, or a wrist-based GPS with maps like the Garmin Fenix 7 or Epix. If you only hike in fair weather and a touchscreen is fine, or just want a solid tool, I highly recommend downloading the smartphone app, Gaia GPS. It’s a piece of cake to use and very powerful, just make sure your phone is in airplane mode so the battery doesn’t drain. You can also check for wildfires, weather, snow, and choose from dozens of map types with a premium membership (HikingGuy readers get a big discount here). Note that I also carry a paper map with me in case the phone dies or gets smashed.

Elevation Profile

Exploration Trail Keller Peak Elevation
While the trail is uphill, it’s very gradual with some rolling sections, and doesn’t feel like a climb aside from some short inclines.

From this perspective you can see that the climb is gradual as the Exploration Trail approaches Keller Peak. Once at the peak, you have great prominence and views.

Hike Brief

There’s not much evidence left from the Bear Fire of 1970, but if you keep your eyes peeled, you can see some burned tree stumps like this.
