Know Before You Go
Tours to see the bats at their best are given by the Yolo Basin Foundation. They cost $14 per person, and children under 15 attend free. However, the tours, which run June through September, sell out extremely fast. There is, however, a way to see the bats on your own. When driving west on the Causeway, take 32 A towards E. Chiles Road. Park outside the gates of the Yolo Bypass Wildlife Area, and go up on the levee for the best bat view at sunset.
