From Yakima, drive west on Highway 410 to Bumping Lake Road (Forest Service Road 1800). Turn left and drive 14 miles to Forest Service Road 1808. Turn left and drive 1.5 miles to the signed trailhead on the left side of the road.

Hiked it 8/10/18. It was a little smokey from the wildfires so the views from the top weren't that great, but it was still well worth the effort.
The trail has water crossing it in 5 places before you get to the Nelson Ridge trail, so you won't need to pack too much water for the dog if you have one.
Once you get past all the switchbacks the trail is not too steep. For me, the easiest way to the top of Mt. Aix was to follow the trail past it and then follow take the little trail up to the top. It's a lot more gradual and easier to ascend.
For the descent we went straight down the steep face, next to the cable, with lots of loose rock. Be careful if you try this route.
A great workout.

This trail offers fantastic views of both Mt. Rainier as well as Mt. Adams and the surrounding area. When we went up, 8/16/18, we only made it about 3.5 miles up the trail. For a less experienced hiker like me, the elevation gain can get a little intense. Be prepared with plenty of water and food! The trail itself was very easy to follow since all of the snow had already melted away. However, there were areas where the trail wasn’t maintained properly; the ground was soft in places and led to a fear of falling down the slope! Other than that, it was a magnificent hike. Several nice little creeks to cross and plenty of places to view the mountains. Hoping to complete the summit once I’m in a little better hiking shape!

Amazing hike. Trail is easy to follow up until the shale rocks. The scramble to the stop is actually climbing. Took the longer route from the peak, that wasn't super easy to follow, especially in the clouds. Alltrails does not list that trail on any map.You can see it on the sat photo though. This trail is about 12 miles.

Hiked this trail yesterday (8/13/2017). Trail is clear / no snow on trail. Beautiful 360 degree views from the peak. It is a bit challenging- lots of elevation gain & switchbacks, but view is worth it. Made good time- about 4hrs up, 2.5 hours down with some time at the top; about 7hrs total round trip for somewhat fit but only moderately experienced hikers.

Photo is taken from the peak facing NW towards Bumping Lake.

Really awesome views, but be prepared for some tricky snow navigation and scrambling. Waterproof hiking boots and gaiters and hiking poles a must; an ice axe would have been really helpful too. See detailed trip report at

Attempted this trail on the Saturday after memorial day 2017. It began well but at 5600ft and 2.28 miles in, the trail vanished under several feet of snow which still remains at the higher elevations. With no map we deemed it unsafe to wander around aimlessly in attempts to get any higher up to Nelson Ridge and Aix. Hopes to complete this later in the year. Also, I have no clue to what the actual length of the trail is. The USFS trail book that I read list it at about 6 miles one way or 12 miles round trip.

Allow enough time to complete this hike...beautiful panoramic views on top. Highly recommend. Chances of seeing mountain goats is pretty good

A great hike. Did this one when camping at the bumping lake camp grounds and had a great time! Finished it in the middle of July, and it had and amazing view of Mount Baker, and of Mt Rainier both! Definitely worth the pain it took to get up. It's a pretty easy scramble to the summit. I would Definitely recommend this trail!

First off, what a beautiful view from the top. With that said, what a brutal trail it was to get there... I'm just your everyday (not so serious) hiker and this trail almost broke me. There were a few cars parked on the trail head in the morning and the traffic was relatively light considering it's in the heart of Bumping Lake. We filled out our permit on the reader board and took off down the wide (but eventually narrowing) quarry spall lined trail. Immediately, the trail turns and we started our ascent. The trail took us over a few small water runs and a few open rock slide areas but it turned to switchback hell at about 1.5 miles and never stopped til the top. 5 miles into the hike and at the top of the ridge, my butt was kicked but not broken and I wanted to keep but going. Unfortunately, i underestimated the amount of time it would take me to reach the top resulting in my turning around and not being able to summit Aix but nevertheless, the views from Nelson Ridge were amazing and i got some great pictures to celebrate the incredible climb.
