The Hillsborough County School’s Nature’s Classroom facility will be open to the public on April 9, from 9am to 3PM. Cost to enter is $10 per carload. Each year, most 6th grade students in Hillsborough County schools will spend several days at this venue exploring nature and the Hillsborough River. It is not normally open to the public, so this is a good opportunity to see what the students will experience.
