BOULDER RIDGE

Located in Alto, MI
80 acres of exotic animals!
I bought tickets online for easy check in but they offer purchase onsite as well.
The admission price includes a safari ride on an open bus with information along the way about all of the animals.
One of the biggest highlights is feeding the giraffes.
We splurged on a bag of mining rocks too and poured them into the mining table. 
Clean paved paths for strollers.
Pack your own lunch, snacks and drinks.  They have food trucks sometimes but not always.  A few pop/water machines available for purchase.
A gift shop for any memorabilia.
