Yes wheelchair accessible. Not very steep climb.
Yes and no steep hills
yes no hills
Some areas of stairs/gravel, but there are alternate paths for those. Only very steep hill is on just one side of an exhibit. Mid grade hill to the Northern Trail exhibits. I've done the zoo in a wheelchair.
There is a little bit of steepness to the pathway they rent wheelchairs there for $10 and they have mobility scooters for $25 a day
