Tecolote Canyon Golf Course is in the bottom of the southern canyon area. There are streams and trails that extend into finger canyons in the area. Wildlife is seen throughout the canyons.

One of the most favored areas in North America for growing subtropical plants, Zone 23 has always been Southern California’s best zone for avocados. Frosts don’t amount to much here, because 85 percent of the time, Pacific Ocean weather dominates; interior air rules only 15 percent of the time. On those 15% days when hot, dry Santa Ana winds blow, Zone 23 lacks either the summer heat or the winter cold necessary to grow pears, most apples, and most peaches. But it enjoy enough heat to put the sweetness in ‘Valencia’ oranges—but not enough for ‘Washington’ naval oranges, which must be grown farther inland. Temperatures are mild here, but severe winters descend at times. Average lows range from 43 to 48°F, while extreme lows average from 34 to 27°F.
