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!

So, hubby, daughter and I have hiked this trail for the last few years, and I would not call this trail "Easy" necessarily. About 3/4 of it is easy, yes. The first 1/3 is pretty flat and a good warm-up. Then, you make the left turn back Southeast up, what I call, the "interval training hill". It's steep, then flat for a bit. Repeat 5-6 times. The top emerges into a gated neighborhood before you walk the ridge behind some homes (with some nicely appointed back yards) and then straight down the hill back to Discovery Lake. Again, I'd not call it "easy", but it's a good training hike for harder hikes.

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!

Great spot, good elevation in the beginning

Trail was beautiful but a bit overgrown, the path gets very narrow in several places. I would suggest bringing a stick as the rattlesnakes are out early this year. Had a very close encounter with one this past weekend! Overall a cool little trail, get confusing at the loop because you run into a sign that says End Trail which ends in new construction, nevertheless, the navigation on the app helped get us on track.

A portion of this loop is NOT DOG FRIENDLY, just a heads up for dog owners out there :) you can take the horned lizard trail but it adds a significant amount of elevation gain, and also an extra half a mile in distance

good view! don‘t like that there is a street and cars at the top!

Very pretty, peaceful and tons of birds. It’s a flat, paved walking trail, so it’s very easy. A plus is that it is adjacent to another trail which is more moderate- The Double Peak Trail- it has a steep upgrade and some nice views. One drawback of both trails is that they are doing some huge construction nearby, building a new neighborhood. So that really interferes with the overall experience.

it's short, easy, relaxing and beautiful

I came here to get some exercise and run up the trail. It's a steep incline at first! Once you get on the dirt path, it becomes easier. There is some loose gravel & rocks so bring some supportive running shoes if you plan to run it. The main path is anywhere between 8-10 ft wide, so you can't miss it, but there are some other smaller paths that break off the main. Once at the top, there are some great views out to the ocean. You can also continue on some smaller trails down the other side of the mountain. When I was here, a Friday afternoon, there as no one else around, so it was a nice quiet run. It was just over 2 miles round trip, but I did do a little extra exploring when I got to the top.

Good got kids. Both my 3/6 year olds can make the loop from lake

I wish someone would have wrote the review I'm about to write to allow you to understand the waterfall is not accessible to little kids or Senior Citizens that aren't FIT or avid hikers. The pics had us excited to take our families on this hike and enjoy the waterfall and the wonders surrounding it from the pics that have been posted. Although, it was a nice little hike it was not possible for the little kids to access the waterfall. I wouldn't recommend anyone who's younger than a teenager to try to go down to the waterfall. Climbing down there was quite dangerous and it's easy to slip on the dirt and severely hurt yourself. I wouldn't recommend going down there unless your confident that you safe and secure. It was very disappointing to the kids because it was not safe for them to climb down on their own or even with an adult so they were not happy to have to stay up on the trail. The only ones that went down there was me and my teenage son. I'm posting a picture of what the climb down looks like to the Minature Waterfall. Good Luck!
oh and if you start to hike up an incline you've gone too far and are now on the Copper creek trail rather than the Copper Creek Falls Trail. The trail is pretty much level with very little hills and bumps along the way.

Easy hike with a 5 and 7 year old. Not well marked so had to rely on GPS map at times.

Pretty steep incline and the terrain is very rocky which makes the hike more difficult since you have to be careful where you step. Lots of routes and confusing we had to use the app to make sure we went the right way after making a wrong turn.

More residential than hike. And a ton of people. “Hiked” on asphalt and sidewalks. The view from the top is good but there were so many people that the peaceful easy feeling was just not there.

Went to the left to start the loop. Most of the path was dirt service road towards the top it got confusing as there is new home construction. There are also a few different forks that dead end. My 3.9 loop turned into 6 miles. Finally got on the right path and caught the creek in the last two miles. Probably better to go late spring when water is flowing. The last two miles is a good single track, i was able to run almost the entire loop, so I would rate it easy/moderate.

First half is all uphill but the views are gorgeous!

Great exercise, but I don’t enjoy “hiking” through subdivisions on pavement. Went on a Tuesday morning in January and ran into at least 20 people. No thanks, I’ll pass.

So this trail is SUPER easy. Great little trail to hit if you have kids or aren't an avid hiker. There are no dogs allowed at all. An overzealous park trail leader even wanted to ticket us for my wife's service dog being with us, so just be aware. There is nothing very spectacular about this hike, and it js pretty over grown and hard to find. Nice if you want a short quick hike though.
