Upper Las Virgenes Open Space Preserve

Overview of adjacent areas

Ahmanson Ranch from near the bottom of Switzerland.

Overview

Ahmanson Ranch (here its historical name is used because the formal name is too much of a mouthful) is a beautiful property of rolling grasslands studded with many oak trees. There are a few official trails (shown in blue on the map below) but many more unofficial trails (dashed brown lines). For the most part, the unofficial trails are much more beautiful to hike and fun to ride.

Unhappily, much of the grasslands have been taken over by mustard so the trails can become clogged in the spring. Also, it's really hot here in the summer so pay close attention to the weather forecast and how much water you have before heading out.

For a number of years, Ahmanson Ranch was a controversial piece of land because Washington Mutual Bank wanted to build 3000 homes here, a golf course and shopping plaza. Besides the concerns about congestion from the extra traffic on the 101 freeway and Valley Circle Rd, this area is home to two endangered species. In 2004 the bank instead sold the land to the state for a park and now it is open for riding and hiking. The propery is owned and managed by the Mountains Recreation Conservation Agency (MRCA).

Determining the names of all the trails was not easy because of contradictions on even the official maps. Here most of the unofficial trails were named as they are in TrailForks but maps for official land managers were used for the official trails.
