The Sandhills Trail is a series of fairly easy park-n-grabs in the area of Sandhills Road in Wilmot Township. All caches are on public land adjacent to the roadway.

Sandhills Road and other nearby roads are usually fairly quiet country roads. That said, always exercise appropriate safety by pulling off to the side of the road as much as possible and use your four-way flashers. If there is a fence in the area of the cache, the cache is accessible without crossing the fence. Most caches are easy park-n-grabs, but some require the use of special tools and/or skills. Pay attention to the D/T ratings and the attributes for hints.

Cache container is a specimen jar wrapped in black hockey tape. Please replace as found!
