I was here on 2 Sep. The hike is closed to the public due to logging activity. I don’t want to rank it high or low.

Went up on Sunday, October 15. Sun was in the forecast and wanted to take advantage of what may be one of the last chances this year for a snowless hike. Got to the locked gate and grabbed my bike and made it the 2.5 miles to the trailhead. The logging road leads just about to the start of the trail. There are a couple of small cairns that mark where to turn off the logging road to pick up the trail. The trail starts just to the right of the sign and switchbacks up for a little while through a recovering clear cut. You enter a forested area for a bit and come out to a fresh clear cut that cuts across the ridge and you gain a little and drop down into the saddle before coming to the ridge where you enter The Brothers Wilderness. The trail really gains elevation from here. You hit a bunch of switchbacks that will have you questioning your sanity (at least mine). Before too long you will be standing on the summit and, if you're lucky like I was, beautiful views all around you. Don't forget to look for the benchmark. The trail was in great shape. I passed the only other person on the mountain that day on his way down and he told me he had just come across a black bear on the trail. He said he clapped a couple times and the bear ran off. I never saw him, but I was thankful for the warning. Had 2 liters of water and a quart of Gatorade. Was just fine on a cooler day. Might want a third liter during the summer as there is NO water up there. Was thankful to have my bike to cruise down the last 2.5 miles back to the car. Long day, legs were spent, but well worth it.

The path is long and narrow at point no more then 12" wide. The mountain views of the hood canal along with sites of the open wilderness are worth the hike. I spent two days down at Jupiter Lake the hike down and up are very physically demanding and due to the dense vegetation require good knowledge of map reading or a very good GPS. There is no direct path down or up with a lot of wet steep drop offs. Spring time when vegetation is less thick ,may be a better time then when I went in late Sept .Weather changed from sunny and warm to rain wind and snow in the blink of an eye.

The gate to the trailhead was closed so plan on adding an additional 2.5 miles each way to your hike, up a logging road.
When you get to the trailhead, there will be an old run-down sign. Look to the right of the sign to see the trail. From there it should be about 7.2 miles to the top. The trail is fairly easy and forgiving until you get to the last 2-2.5 miles where you'll do the majority of your climb. Great views of Mount Jupiter, Two Brother, and Mount Rainier. Lots of loose rock on the trail. Parts of the trail are overgrown but still easy to find your way! Beautiful at the top. We could see Mount Rainier, Mount Adams, Mount St Helens, Two Brothers, The Canal, the Duckabush River. Totally worth it!

Tough but worth the views. It's actually 14.4 miles. Make sure to check if logging road gate will be open (usually is after May 1st). Otherwise add 5 miles to your hike.

Cool trail close to Kitsap county. The trail is not maintained and at first glance the real trail head is next to the sign and goes to the right its very tiny at the start we didn't notice it right away and we wasted about an hour or so so look out for that. We went on October 25th 2015. The entrance was closed due to hunting season so it adds a mile and half to the trail which wasn't bad. There aren't any toilets so come prepared, lots of water. Would go again watch out for loose gravel and there's a lot of fallen trees in certain areas would go back.
