About 7 miles east of Visalia is Kaweah Oak Reserve, home to 324 acres of valley oak trees, which once stretched from the Sierra to (long-gone) Tulare Lake in the valley. Nice for a short hike, it's also a rare glimpse into the valley's past before the orchards and vineyards took over. From Hwy 198, turn north onto Road 182; the park is about a half-mile along on your left.
