2.1 miles round trip, easy–Stroll down the Solstice Canyon Trail and look for the stone walls of the Keller House, built in 1903 after a fall wildfire. On your way upstream to the Roberts Ranch House, see if you can spy the low concrete retaining walls of a former fish pond in a grassy area overlooking the creek. Many other clues to the past remain even though the Roberts' family home burned in 1982. Walk across the creek into the ruined remains of a hidden sanctuary and garden. Imagine another time when giraffes, camels, buffalo, African deer and exotic birds roamed the Roberts' Ranch.
