This cache is in the forestry area on the east side of Hamilton Park. Since this is a wildlife habitat, you need to stay on (dirt) trails at all times. Note there has been storm damage in January 2024. So I have been updating the description how to enter this forestry area here:
Enter from near the two tennis courts. There is a trail that starts at a ca. 20 foot long horizontal metal bar, next to a very thick fallen tree log. The cashe is at an asymmetric twin tree. You do have to go into that area a little bit, but don't cross the creek. In rainy weather, it can be slippery, use caution on the sloped trails.
The 'hint' section gives you an accurate description how to get to the cashe which may make it easy, maybe try without that first. Have fun!
