A local favorite, the Monserate Mountain Trail loop hike features a tough little climb with some unique trail markers. First off, you’ll climb about 1,200 feet straight up the mountain, which is challenging but doable. And along the way, you’ll have trail markers for every ten stories of the original World Trade Center, put there for the Fallbrook Firefighters 9/11 Memorial Hill Climb. The top offers panoramic views and a fun summit area that often includes a flag. You can head straight back down or hike a loop that rewards you with more great views into the Agua Tibia Mountains.

Where is Montserate Mountain?

Montserate Mountain is located just off of I-15 in Fallbrook, CA, in the northern part of San Diego County. Use this trailhead address:
243 Horse Ranch Creek Rd, Fallbrook, CA 92028

The parking area is big but does fill up. This is a popular hike with local hikers, runners, and dog walkers.
Montserate Mountain Trail Directions 4
There is additional parking in the dirt lots south of the trailhead.

There are no bathrooms or water fills at the trailhead.

Gear for the Hike

While plenty of people do this hike in casual or fitness clothes, you’ll fare better if you have light hiking gear.

Garmin Inreach Mini Beacon

Stay Safe Out of Cell Phone Range
If you’re not familiar with the Garmin InReach technology, it allows you to send and receive text messages where you don’t have cell phone signals. You can also get weather reports and trigger an SOS to emergency responders. Even if you don’t have an emergency, sending a quick message telling a loved one that you’re okay or are running late is well worth the cost. The Garmin InReach Mini (REI | Amazon | My Review) fits in your palm and weighs next to nothing.

Lone Peak 5

Altra Lone Peak 5
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 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. Watch my video explaining why they are a great shoe 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.

How Are You Going to Navigate This Hike?
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 6. 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.

The Monserate Mountain Preserve is a diverse and fragile habitat, so please respect any closed areas and stay on the trail.
Montserate Mountain Trail Directions 1
This is what the 9/11 markers look like. There are 11 markers on the way up, one for every 10 stories of the 110-story original World Trade Center. They were put here to honor the fallen first responders who lost their lives on Sept. 11, 2001 and all those dedicated to saving the lives of others. They also serve as markers for search and rescue. If you have to call in an emergency, just give 911 the marker number and they will know where you are.

Elevation Profile

Turn by Turn Directions

Montserate Mountain Trail Directions 5
Hike through the impressive ranch gate at the Monserate Mountain Preserve trailhead.
Montserate Mountain Trail Directions 6
After a few minutes you’ll come to the gate for the Preserve, hike on through
Montserate Mountain Trail Directions 7
And now you start the climb. You can see from this picture how rocky the trail gets in some sections. Avoid any small side trails and stay on the big wide trail climbing up.
Montserate Mountain Trail Directions 8
You’ll see the trail climb in front of you. And given that this is a popular hike, you’ll probably see other hikers heading up and down, giving you clues as to where you will be next.
Montserate Mountain Trail Directions 9
When you get to the junction, make the left to continue to the summit. There’s also a trail marker here pointing left to the summit. You’ll be coming back on the loop at this junction.
Montserate Mountain Trail Directions 11
The climb is steep, so don’t forget to take a break and look around. You’ll have I-15 in view for all of the hike, which is not the prettiest, but as you climb, the surrounding countryside comes into view.
Montserate Mountain Trail Directions 12
Some sections of the trail have pavement, but it’s not long.
Montserate Mountain Trail Directions 13
When you get to this trail junction, stay straight (and up) toward the top of Montserate Mountain.
Montserate Mountain Trail Directions 14
Here’s the detail of that marker, 0.6 miles to go to the summit. There are a few of these along the route.
Montserate Mountain Trail Directions 15
You have a few minutes of respite as the trail levels off.
Montserate Mountain Trail Directions 16
And then goes up a rocky section again.
Montserate Mountain Trail Directions 17
The trail winds around and you get good views to the south.
Montserate Mountain Trail Directions 18
Soon you can see the summit from the trail.
Montserate Mountain Trail Directions 19
When you get close to the summit, take the spur trail to the left.
Montserate Mountain Trail Directions 20
And here you are, the summit!
Montserate Mountain Trail Directions 21
At the summit you’ll get your first views to the east. The big mountains are part of the Agua Tibia Wilderness. Just beyond these peaks you’ll find Palomar Mountain.
Montserate Mountain Trail Directions 22
Leave the summit and make the left to continue on the loop trail.

If you want to just go back down the way you came, make the right here and follow the same path back down.

Montserate Mountain Trail Directions 23
As the trail heads south you’ll get some nice views of the surrounding countryside. You’ll be hiking down the ridge in front of you.
Montserate Mountain Trail Directions 24
Start the descent down the ridge. You’ll see the trail unfolding like a ribbon as you descend.
Montserate Mountain Trail Directions 25
When you get to the small rise, take the main (and semi-hidden) trail to the left. You can also go straight to continue but the descent is steep and slippery.
Montserate Mountain Trail Directions 26
There are stairs right after that last photo, taking you downhill safely.
Montserate Mountain Trail Directions 27
Pavement starts and the trail passes a spur to a water tank on the right. Hike straight to continue downhill.
Montserate Mountain Trail Directions 28
When you see this side trail to the right on the descent, take it.
Montserate Mountain Trail Directions 29
Hike over the ridge and enjoy the views.
Montserate Mountain Trail Directions 30
Rejoin the paved section and go right.
Montserate Mountain Trail Directions 31
And immediately after that, make the next right.
Montserate Mountain Trail Directions 32
Hike through the gate and continue. You can see the trail climbing up in front you. You’ll do that climb to arrive back at the loop junction.
Montserate Mountain Trail Directions 33
You might notice a trail running parallel to the left. You might also notice that it doesn’t have a climb. Avoid the temptation to go off-trail through the protected area and cut across.
Montserate Mountain Trail Directions 34
The 200 feet of uphill might hurt if this was a challenging hike for you. Take your time and know that this section is short.
Montserate Mountain Trail Directions 35
When you get back to the intersection, go straight and retrace your steps back down the hill.
Montserate Mountain Trail Directions 36
In no time you’ll be back at the trailhead gate. That’s the hike!
