All these caches are BYOP.
The trail up to the Pinnacle is not hard. A slight up hill trek all the way to the top. I place 8 in a loop to the look out and back. All are within 75 ft from tail. Do take caution due to the weaving mountain bike trails on the Pinnacle. Enjoy the hike. trail head is off of Summer St.
Here is a mape of the trails.
