I really enjoyed this hike mostly for all of its historical content. The flume is so cool! Trail is accurately labeled moderate and just enough challenge to keep me interested

Did this hike on a Saturday morning at sunrise, was the only person at El Monte County Park and the only person on the trail. Lovely hike with a lot of switchbacks, a ton of wildflowers, cool rocks, and great views of the valley. The bench with the Blossom Valley Summit plaque is a good place to end the hike and head back, if you continue along the all trails track it just takes you between a couple houses to the roadway to the south, the bench is a much nicer finishing point.

This a an easy hike compared to Cowls mountain.
Very beautiful with lots of green grass, trees and rock formations.
Excellent views along the entire hike.
We went on a Monday afternoon. It was cloudy and cool and we only saw 3 other hikers in the 2 hours it took to complete the hike.
There are wildlife warning signs but we did not see any lions or snakes and we were scanning the hills constantly.

Not bad. Kinda lackluster ending in blossom valley feeling like a you're tresspassing in someone's backyard but overall I liked it. Very well marked and easy to access. Awesome view of the mountains. Went with my seven yr old and two dogs, no issues except for a tiny blister.

We didn’t have much time so we only made it from the park to the tunnel. Which was a great quick workout. You start climbing straight from the park in area 8. We only saw two other couples on the trail on Saturday. We will go back and climb both sides. If you aren’t in good uphill condition this may hurt a bit.

Very steep switchbacks. The history of the flume is very cool. The trail just sort of dumps you out into a new McMansion urban sprawl community so that's weird. But the views of El Cajon mountain on the way up are great.
I'd give this a 3.5 but apparently we don't get half stars. Very lightly trafficked so I bumped it up.

A lot of switchbacks up and down that give a solid workout.

Nice cool breeze coming out of the lower end of the Flume Tunnel which is a welcome treat going up, or down! Locate the tunnel between the two sets of switchbacks ~half way.

We saw many small lizards but no snakes; nonetheless, keep your wits as instructed by the signage.

The end of this trail is somewhat disappointing, but it does provide a view of the ocean over one of the houses.

Overall this is a great hike where you can see beautiful flora, and fauna, as well as a few historical structures while also working on cardio, and your leg muscles!

This is a dangerous trail for mountain bikes. But great steep incline. The trail has a ton loose rocks and dirt. Should only be a hiking trail.

Used 2 cars with a buddy and started from the top so all downhill for us. hike it when it's cooler. More enjoyable. The flume has an interesting history. read about it.

At El Monte Park there was no place to park until after 8 AM including beside the road as that was all posted as no parking. There is one parking lot across the road from the park which was free once the gate was opened. The trail was well maintained and was an actual foot trail; not an abandoned road called a trail. The beginning is a fairly steep grade that switchbacks. There is a historic marker at about 1 mile. A nice view of a tunnel used as part of the flume system there. I went up to the summit and continued until the trail ended at Creek Hills Rd. among new gigantic houses. An earlier start could be made from this point as there are no gates. I went back to the first historic marker and followed the trail westbound, where the flume actually ran. I saw two more historical markers then the trail is overgrown, but easy to find. I continued quite a ways then returned by the same route for a total distance of 9.5 miles. An interesting hike and the section following the route of the flume was mostly flat, easy walking. The trail to the summit has great views of the area. A very pleasant, peaceful area and the historical marker are interesting.

Fun little trail with an interesting history.
Convenient parking and notes on the history along the trail.
Rated "moderate" for the switchbacks at the beginning which get the heart rate going. After that it's pretty flat and narrow.
Very nice views and you can hook into the Lake Jennings loop at the top.
Wild flowers are everywhere right now!

This is a great trail. We had little ones with us so we only did the first hill. The trail takes you up 1 hill, down that and then up a much bigger one. Next time we will leave the littles and complete the whole trail. Clearly marked, good path, and still a good challenge. Really nice wild flowers. Highly recommend this.

Went with a large group of people a few days after rain, so the park was very green! Clear, well-marked trail made it easy to navigate all the way to the road (Creek Hills Rd). Moderate hike with lots of smaller, less-traveled trails made it easy to explore the area. Some cool historical significance on this trail - the remnants of a flume (an aqueduct) are at the bottom of the valley, almost at the halfway point from the road. It was used to transport water to San Diego!
