I didn't notice any toilets, rubbish bins, play equipment or sports facilities, so if you're looking for a reserve with those facilities, I'd probably recommend nearby Wallington Reserve instead.
Overall, it's a nice place for a nature walk or a picnic.
If you're visiting the reserve with young children, just be aware that the reserve is unfenced, and highway can be very busy (with an 80km speed limit in that section). The creek is also easily accessible.
Parking: As you drive into the reserve, there are small areas for parking next to the road and turning circle. Edsall Reserve Bus Stop is also located just outside the entrance to the reserve, for bus services into Geelong.
