A great hike for beginners or intermediate hikers.
This is a great workout hike and could easily be done several times a week.

Good for afternoon walk! Feel like you’re in a forest. Hug the landfill buildings until you get to trailhead. In and out within an hour with time to poke around waterfalls.

Nice steep but smooth hike! Great 360 degree view from the top! Started the hike around 0800 and it was perfect out.

Did this hike around 0800 in the morning and was the only person on the trail the entire time. Very cool area and beautiful little waterfall when you get to the old mine camp area.

This was a moderately steep, rocky trail through scrub and bushes. It was full sun, so bring water and hats. You are always aware that you are near an urban area, traffic noise and farm equipment could be heard. Very few people were out on the trail, and we saw a variety of birds and evidence of coyotes. It is a typical San Diego county urban hike!

Great hike to burn those calories! I started on the main trail from Discovery Lake through the neighborhood above. Steep to start, but there is a paved road to make it easier. Once past the residential area, the trail gets more rough. I took a few off-the-main-trail paths that got very steep and loose towards the top. There are a few cut-through paths that are challenging and feel like you're getting lost, but you always end up at the top. Great 360 view. You can see the ocean on q clear day. Took less than 2 hours round trip at a brisk pace.

Fun trail, I did the Ridgeline trail to double peak. Will definitely be back to explore other routes. Trailer parking is limited, would not suggest a large gooseneck trailer, Trailer parking may be difficult on a popular day. Also, a busy road is nearby and would be scary if a horse got loose. I recommend not taking a green or new horse. I went during the week, in the middle of the day. Footing was decent, a few rocky areas, I was able to trot and canter a little. There are mountain bikers doing single tracks and pop up out of no where, my horse did spook a couple times but the mountain biker did stop and was very respectful of my horse. Overall nice views, nice trails will be back 鸞

Like the other comments showed, the views along this trail aren’t the best. You do travel through a neighborhood but it’s a quiet one. If you’re in the area and looking for a quick afternoon burn, this is a good hike. It’s pretty short but the hills are steep the entire way. In the loop shown by the map, there is some interesting single track worth investigating.

Next to very busy road and very ugly industrial buildings. Must cross several intersections along route. There’s a lot better places to ride your bike in San Diego. Although I appreciate the city putting in this bike path I don’t recommend.

It’s an okay hike. There are a lot of side trails and none of the trails are marked, so bring your phone with this app unless you’re looking to wander about or you have an excellent sense of direction. Although you can see for quite a ways, you’re really only going to be able to see subdivisions. If you live close by, check it out, but don’t drive far for this one.

It’s a nice hike but you need to watch where you walk on part of the trail because it is rocky. I loved the bridges and the water was relaxing.

It's a nice local suburban hike with about a 1000' gain on wide, well-marked trails. It gets better once you get to the top of Stoneridge housing development - at the first water tank - and away from the houses. Nice views once you get high enough. Can be somewhat crowded on weekends, but not too bad. Cool that you can get a climb and a view like this without having to drive too far. Nice spanning coastal views on clear days and usually pleasant breezes to cool you off once you hit the top. Cool to hit Double Peak just around sunset.

Too many houses around during some of the trip.
Saw a coyote though so had a good experience. Moderate difficulty.

It is convenient and nice views from the top. I am not crazy about pavement and looking into people’s yards. So many homes. Prefer to be away from it....

Great views and a good challenge on the way up.

Went for a mid day stroll with my medium sized dog (40lbs) and was on the back side (at the bottom of the steep incline overview of ranch/nursery/greenhouses) eating lunch when I saw a light brown/tannish animal. Thought it was a coyote but it moved swiftly like a cat, large muscular shoulders and body and thick legs and paws. Definitely not a coyote but 99.9%sure a MT LION. Seen on 5/17/18 at 1:30pm. I picked up my dog and huddled our asses out of there. Carried a medium size rock with me, luckily there were a lot of large rocks on the trail to throw at the cat if needed. Thankful we didn’t see it again, probably 1/4 mike away down in the field near the mountain slope. Be careful and prepared!

The trail down to the falls has been blocked off. Still a pretty decent little hike though

I really don’t want my view to be houses! Just me.

Very easy hike. We went the wrong way.. so if you go up on the incline you are going the wrong way. Came down and we went down the other trail but the kiddo's were done so we didn't see the waterfall. Will come back again and try the right path to the waterfall. Want to keep the 11 - 15 years old happy for next hike.

What a fun hike!
The Loop can get a bit confusing but having this app helps!

You can also access Copper Creek Waterfall from the La Costa Oaks side off Camino Junipero Road. Follow the fire road where the large power lines run east, and then catch the trail down into the canyon. There are remnants of the old copper mine, including foundation slabs, mine tails, and even the small entrance to the old mine. A cool little hidden gem, and a nice tiny swimming hole for those brave enough to dip a toe.

This trail is a hidden gem! Very flat and short trail so excellent for younger kids.
The parking is in a big open area in front of an abandoned looking industrial building. If you are driving west on San Elijo rd, you will pass an Albertsons on the left. The parking area is about 1/4 mile past it. Once parked, pick a trail that heads towards the building. Keep left. This should lead you to a somewhat paved road next to a fence. Keep walking down and you will pass some storage lockers to your left. The trailhead is a little under 1/4 mile past it. At the trailhead are some walking sticks that you can take on your hike and return once you are done- so cool.
About 1/2 mile in, you will come across another trail sign with two paths. Stay to the RIGHT. The other way is more uphill and takes longer! Keep going on the right path and you will start to come across some nice footbridges. After that, it’s only another 1/2 mile until you’ll reach the waterfall. The waterfall is down a hill from the trail and is tricky to get down there since it’s steep, rocky and a little slippery. But you can still see it from the top.
Overall, this hike is a little under 3 miles out and back and made it the perfect post dinner family hike during the week!

I’ve done every trail on this mountain at least 5 times, if not more. Great hikes with lots of single tracks. Great for everyone and dog owners too.

Ensure you watch out for snakes in the summer months, as they are plentiful but usually not in plain site (off the trails). There have been mountain lion sightings and we saw a large bobcat at night, but I don’t know of any interactions with humans or pets.

Have a blast out here and enjoy. There are a lots of trails and lots to see.

Good little steep loop for a weeknight hike. the water view is at the bottom before you climb much and the views from up top are nice but are facing the sun in the afternoon/evening.

*****TICK WARNING*****

*****no pets allowed*****
:( came home to find what I believe was a tick on my shoulder.. however it was an amazing trial!! definitely enjoyed the peacefulness! the trail is not marked and had to rely on the Alltrail map to guide me. Heard a couple of rattlesnakes however didn't see them. my suggestion is to bring a pair of trekking poles or even a good couple of sticks. Had to use them to climb down to the waterfall and if you don't have good footing most definitely higher chance to slip and fall. Cell service was good out there (TMobile). The scenery was absolutely phenomenal phenomenal!! I only saw 2 people on the trail. Highly recommend to do this trail. was super easy and definitely kid friendly.

I’ve hiked on this trail with my two dogs and it’s a nice trail!
