What Travellers Say
Reviews Summary
Visitors consistently praise the Yolo Causeway bat viewing as an amazing and spectacular free activity, especially during summer evenings. The sheer volume of bats emerging is a highlight, offering a unique natural spectacle. While the wildlife auto loop is appreciated for birdwatching and general nature observation, some note that arriving early is essential due to crowds and limited parking.
"Easily one of my favorite places to visit for photographing wildlife. It's an auto loop so you don't need to get out of your vehicle. It's where I see the most White-Faced Ibis. I recommend birding out there."

"Going to see the bats and the sunset is one of the best free activities in the Sacramento/Davis area.
Update: the bat colony is more popular now! We arrived too late on 7/16 (8:30 pm) and had just missed the bats. We also noticed that all the parking near the prime viewing area under the causeway was taken, so we returned 7/17 at 7:50 pm and saw the bats emerge at 8:15-8:25 pm. It was really spectacular. Go bats!"
