Introduction

This trail guide begins at the eastern end of the Hidden Spring Trail.
To reach the trailhead, begin at the parking lot at the main entrance to Daley Ranch, which is at the southernmost part of the property, just north of Lake Dixon at the top of La Honda Drive in Escondido. The only toilets nearby are at Lake Dixon, which have running water. It is free to walk through the Lake Dixon entrance to use them. A porta-potty is at the Ranch House at Daley Ranch.
Take the Ranch House Trail, which is the paved main road of Daley Ranch, north to the Ranch House. Continue north on the Jack Creek Meadow Loop to its signed intersection with the Hidden Spring Trail.
After completing the Hidden Spring Trail, you can return to the parking lot via the Engelmann Oak Trail, Cougar Ridge Trail and Boulder Loop Trail. The entire loop hike is ~8.5 miles with ~1100 feet of elevation gain and loss.

Number of Unique Taxa On This Trail

The following histogram gives the number of trails in our database that contain each taxon on this trail. There were 88 trails in our database when this histogram was made; two trails, including this one, are at Daley Ranch. A number of "1" means the taxon has only been found on this trail among the trails in our database; a number of "2" may indicate taxa found only at Daley Ranch.

We found 8 additional species not in the above table, since they have not been fully identified yet. The unidentified ones are marked with ?, sp or ssp in the id? column in the guide, and do not have any number given in the #all column.
Fieldwork Dates and Summary of List Changes With Time

The following table gives the dates the trail was walked and taxa recorded. After each visit, the table gives the total number of taxa on the list and the breakdown of the taxa without positive identification. See Explanation of Plant Trail Guides to understand the symbols below.

Comments On Specific Species

Isocoma menziesii. In our experience, the subspecies are not separable in Southern California. See Comments on the Jepson Manual and A Flora of Southern California by Munz: Isocoma menziesii.
Marrubium vulgare. We removed the only occurrence on this trail, so we hope you don't see any specimens in the future!
