Spring-Fall
A variety of hill country wildflowers bloom at different times through this time period. The various flowers each attract specific types of wildlife, including butterflies and dragonflies. The timing of when the wildflowers are in bloom depends on rainfall and temperatures but there are always interesting wildflowers to be viewed along the various trails.

Fall
Thousands of monarch butterflies and hawks migrate south through the refuge in fall.

Winter
Vast flocks of wintering robins and waxwings can be viewed. Winter is also a great time to hike the various trails and just enjoy the beauty of the hill country without the heat of summer.
