To include wearing the property clothing and shoes or boots. Make sure you know your routes because a wrong turn could not end well. With San Diego's multitude trails you got to try at least one or two!!!! It's like I always say if you're in the Carlsbad area looking for a trail that anyone can finish, try this trail.

You eventually come to some falls that are partially obscured by vegtation, but that sound is a great reward for the walk. I imagine this trail is only worth it when there has been some rain, as it was soo green, but by Summer that will all be gone. Make sure to wear pants as the trail is literally overgrown in some spots, and you can never be too cautious with ticks everywhere (we found one on our canine companion).

For a quick run, the Rancho Carrillo Trail got the job done. While not the biggest, longest,…read moretallest, or most scenic trail around, I enjoyed it nonetheless. Maybe the key to that was ease of use. Parking was easy. & not a lot of folks out, so I had the trail mostly to myself. Over the 2 short laps I ran, for a total 3.33 miles, there were some nice elevation changes & interesting enough features to look at. & for a run, it's good stuff for a trail to be able to take your mind off of the actual running. Rancho Carrillo Trail did that.

Just put in directions to the Carillo elementary school and as soon as you enter the school lot, take a sharp right to park in the public lot, no pass or payment needed. (if you turned left, you would be entering the elementary school parking) It's kind of hidden, hence why I kept passing it. Drum roll please, I finally found it and could not have been happier. Hardly any cars, maybe 1 max at 7 a.m. Come early while its overcast and not so hot out. Once you park (free parking lot off PASEO ESCUELA and POINTSETTIA LANE), there are (2) ways you can take. Look at the paved ground and decide for yourself. Either way they loop around. It's a total of 2 miles from the car and all the way around of staying ON TRACK, however, I love all the random paths & trails you can take to be adventurous from the main trail. It's so nice. I personally enjoyed the scenary. It was paved for the most part. I loved seeing a little bit of history. We did not go into the historical ranch, as 1) it was too early and 2) they do not allow dogs however, we could go up to the fence, and peak thru. It was so pretty, look at all my pictures. I loved this trail, it was a nice workout for a brisk walk or run. some incline here and there. Great for dogs and really quiet.

We parked our car in a lot across the street from the sign that says "trail" in parking lot off of el fuerte street. It's a nice trail with lots of greenery that's about 1.3 miles. It splits off into 2 parts a good .5 mile in where if you go right it's steeper incline and left is pretty flat. Perfect for dogs and anyone if you avoid the steeper side!

Beautiful mountain that is littered, but I'm sure the city of San Marcos will plan a city-wide beautification project. Update: There's a bunch of cords and ropes going down the white "P" rock formation, but it gets woodsy, and I felt an ominous omen. It feels like a barbaric encampment (Civilization fan here), so I climbed back up and enjoyed that little rock-climbing/bouldering workout and took a different trail down towards Borden. What a relief to see Palomar College across the road because I feel this is not safe for solo travel. GPS and supplies can only go so far. Make sure to go with an official Meetup or well-known FB hiking group and carry emergency equipment with you like plenty of water, a first aid kit, sunglasses and a hat in the hot summer months, maybe even a beanie/scarf and a mini-umbrella during the cold winter months, and a hand-crank radio. (and sunscreen!)
