Take a walk down the Rose Bay trail and find the crow's nest. While there is plenty of wildlife in this nature preserve you are not sesrching for a bird's nest.
A crow's nest is structure in the upper part of the main mast of a ship or a structure that is used as a lookout point. This position ensures the best view for lookouts to spot approaching hazards, other ships, land or the nearest geocache.
The posted coords will take you to the crow's nest. Once you climb to the top, position yourself in the northeast corner of the nest and use the captain's brass spyglass to locate the cache location. Bugs have been known to take a nap within the spyglass, there are plenty of natural pipe cleaners should the tube need cleaning.
