There's a nice Peach Festival in Weatherford. It's called the "Parker County Peach Festival" and is 23 years old.
Medina has a fabulous apple festival. But I haven't been for a few years. Here's some info I found on the web:

"Baxter Adams brought apple farming to Medina in 1980. His experiments with orchards of dwarf apple trees were so successful that other hill country residents started clearing cedar and planting apple trees. The first apples were ready for sale in 1984. The dwarf trees produced regular-sized apples sweeter than large-tree varieties and able to tantalize consumers with tree-fresh apples in mid-summer when only last year's cold storage apples were otherwise available. Between 1,000 and 2,500 dwarf trees could be planted in one acre and an industry was born. Apples revitalized Medina. The Texas Department of Agriculture declared Medina the "Apple Capital of Texas" in 1989. Some 300,000 trees in the Medina area produced 100 tons of fruit in 1990 as the population hit 515.
Meanwhile, with no tax revenue to support the unincorporated town, Medina residents pulled together to form the Texas Development Corporation and turned apples into cash for the town by hosting an annual fundraising event, the Medina Apple Festival.
