Beautiful, but can be a tough hike. On the way up there's some logs and fallen trees commonly used for resting. In particular, I love the moments you walk across the bridges over streams and often have a great view down the mountain.

This hut is now repurposed as a shelter for hikers, but had its origins in the post-World War II era. It was originally designed to protect guns on navy ships and then was later repurposed as equipment shelter in the radio industry. Definitely a unique stop on the trail.

Poo Poo Point Trailhead is a popular spot to start an adventure. In this parking area, there are a few porta potties, trash cans, and ample parking. Hang gliders sometimes take off from these mountains, so you could spot a few in the air. Poo Poo Point is open to hikers or mountain bikers, but the sign in the parking lot can be accessed by road bikes or regular tour bikes for a photo opportunity with the "Poo Poo Point" sign that might give you a good laugh.
