Sometimes there's a good-sized pool of water in this basin; most of the time, though, it's a boggy sort of wetland. Either way it's home to an interesting riparian, sage scrub and southern oak habitat.

Yes, dogs are generally welcome in the South Hills Wilderness Area, but they must be kept on a leash. For an off-leash experience, you can visit the large, fenced-off dog park located at South Hills City Park on Mauna Loa Ave, which also serves as a primary access point to the trails.
The main access points with parking are at South Hills Park on Mauna Loa Avenue and near the underpass for the 210 Freeway on Bonnie Cove Avenue. South Hills Park is a popular starting point and offers ample parking.
Yes, the area has several options for beginners. A great choice is the Michael D. Antonovich Trail loop from Life Pacific University, a gentle 2-mile (3.2 km) walk that takes about an hour.

Spring is a particularly beautiful time to hike, as the hills often come alive with a vibrant display of wildflowers like Angel Gilia and Dove Lupine. The cooler months from fall through spring are generally the most comfortable for hiking. Summer can be very hot and dry, so if you hike then, be sure to go early in the morning and bring plenty of water.
Absolutely. Many trails in the area can be combined to form loops. For a rewarding circular hike with great scenery, consider the View of Puddingstone Reservoir loop from Claremont. This moderate route offers changing perspectives as you complete the circuit.

Both offer great local hiking, but with different characteristics. The South Hills Wilderness Area is a semi-wilderness park known for its rolling hills and wide, exposed ridge trails with city views. Big Dalton Wilderness Area, located within Big Dalton Canyon, often feels more secluded with trails that follow a creek and wind through canyons, providing more shade and a slightly more rugged feel.
