Olio Fields is a series of ball fields(softball, baseball) directly southest of Hamilton Southeastern high school and falls in the jurisdiction of the Fishers parks department. The fields and dugout are well maintained and there are several batting cages you can use. Additionally there is an out building and playground. But oy parking… what a mess. In ball season… if you want to park near the fields forget it. It is a complete clusterbomb of cars wherever. Seriously bad planning on the part of the parks department. Presumably you can park at the high school and walk(maybe that was the intent?) but they rope off the soccer field just north and it’s a bit of a hike. And I didn’t see anyone walking from there… they were just trying to get situated closer to the fields. All in all… a nice entry to the parks department that is IMO packed in an area way too small for intended use.
