Backpacked to 4th of July Pass via Thunder Creek trail. Very clean and scenic trail.

We backpacked 4th of July Pass via Thunder Creek Route. Mild, steady ascent through thick, green forest that initially follows a blue-green river. The trail begins switchbacking up to the pass with a few stream crossings. It gets increasingly more scenic the farther up you go, ending up with great views of surrounding peaks and glacier at the top. Makes for a great day hike or an easy but work-for-your-dinner overnight backpacking trip. Campsites were clean and so was the pit toilet. (A rarity for NPS!) The trail was well-tracked with only one downed tree. Would highly recommend!

Great Trail. Little bit of Traffic but not bad. Took our dog on the leash, that's the great part! Had a blast! Make sure to Gas up in Marblemount first! There's Colonial Creek Campground just down the road from the trailhead too!!

Great walk with the kids. Lots of little informational posts!

I hiked this trail mid June. I have mixed feelings about this trail as my motive is to move away from noise and buildings when hiking. You hear the highway during much of this hike and the power lines kind of ruin the views. The trail does have some value as it offers a gradual climb (easy enough for most hikers) starting in a peaceful forest. The only sounds are the many song birds. You will cross a few snow melt streams without any problem. The avalanche presents some boulders to climb. This is a very short area, though. Take notice near the end of the boulders a low cave like area that looks somewhat filled in, yet blows cold air. Great way to cool off. Next, is a short off trail look out near a power line tower. I spotted some warblers there. The trail moves close to the gorge edge. Here you are exposed to the sun and need sure footing as the drop off can be dangerous. There are a few limited views along this part which include the lake, mountains, and cliffs. Just before the trail descends to Ross dam is a lookout. The view from route 20 is actually better then this one.

Backpacked out to Roland Creek campground (about 7 miles in) and back, pretty unimpressive to be honest. It starts out pretty nice, but fades to generic green tunnel with no vantages, distinctive features, or anything of note really for the majority of the hike, although Roland Creek itself at the end is nice.

That said, it looks like the trail might get a bit better if you go a bit farther than I did.

Hike was not what i expected.. probably should have read more comments … It was a very easy trail with no reward at the end barely a view… But when you drive to the Lookout it made up for the 3 Hour Drive. Everyone’s photos were taken from the look out..you drive to.

Popular hike, busy on weekends

I backpacked to Junction it was great

It’s ok. Not my favorite in the park

Great easy out and back hike. Great views! Recommended

Hiked on 6/9/18 - snow at about 3 miles kept me from making it to the lookout. The trail was tough to follow and eventually I lost it.

In any conditions it is definitely a challenging push - especially the first 1.5 miles. I’ll be back in the summer to make sure to top out!

Not a huge fan of this trail. The views at the base of the lake and Diablo Dam is pretty but a bit disappointing with all the power lines strewn across the lake. The hike is a bit steep in the beginning but you get a small reward halfway through with views of the lake from above. The rest of the hike is not very exciting and all you get at the end is a view of more power lines and Ross Dam.

Beautiful views from the top

The trail was pretty easy with great views of mountain peaks most of the way. The views of Diablo Lake are amazing. Definitely wear good, supportive shoes to make your life easier, lots of lose rocks that can make it tricky for someone older or not so graceful.
No complaints at all and will be back!

This was a beautiful trail! The lookout point is not what we expected as there were power lines and a dam in the view but it was still very beautiful. If you're looking for views I wouldn't say this trail is the best as far as vantage point but there's still so much to see. To see the lake as depicted in some of the photos we were told to head to Keplar (name?) trail which was about a 3/4 mile drive past the Diablo turn-off on the highway. The trail was well marked and easy to moderate. It was fairly busy but still very enjoyable. Highly recommend!

Beautiful view

This trail can be very confusing is you haven’t hiked it before. From the trailhead, you hike about a quarter mile before you get to where the trail actually starts! There is a wooden vertical “Diablo Trail” sign to the left at the actual start to the trail. I accidentally wondered an hour out of my way going the wrong way today and had to wander back to actually start on the correct trail!

The first 1/2 mike is steeper and gets rocky in some places. Then the trail levels a bit for a while.
I hike passed the lookout point, but didn’t make it to the lake. The lookout point isn’t great, since it has power lines in your view. If you actually go about 5 more mins past the lookout point, you’ll get a much better view just from the trail.

To get to the viewpoint, you’ll scramble over some large boulders.

Again, I didn’t make it to the lake. I wandered back to the trailhead parking lot and went down to the lake area there.

Just pay attention to where you start and when going back. I got so lost, turned around, and confused. The trail isn’t marked at well as it could be.

Simple hike. Don't let the creeks in the beginning stop you from this one. They aren't too difficult to cross especially with trekking poles.

Lookout was gorgeous, have to go up a little more for the actual hike.

Great early season trail. Lots of down trees but nothing too gnarly. Don’t blow your ACL

Beautiful hike. We got to the trailhead at 10 on a sunny Sunday morning (75 degrees!). I definitely expected it to be more crowded, but it wasn’t until the 2.5 mile mark that we saw another hiker. I think this trail is on the easier side for moderate—was testing out a new backpack and carrying extra weight (for training) and we still cruised along. Saw one snake (Northwestern garter snake) and one chipmunk, but that’s it for wildlife. Enjoy the hike!

Recommend snow shoes, poles, and spikes to attempt trappers. Still snow everywhere, lake frozen over.

Gorgeous day to enjoy the fresh mountain air. Beautiful drive and views along the trail.

Good short trail to do if you only have a little time

Hell of a route! Potentially the best views in Washington for a ROUGH one day hump; 2 days strongly recommended.

Be aware of the talus field right out the forest. The toughest section in my opinion. Also, there are crevasses on the glaciers (to apt to hit them on Inspiration Glacier).

Took just under 11 hours up (hit crevasse at 8,400 and turned back...). 3.5 hours down. You're a bit over halfway, effort-wise, when you hit the "notch" in the ridge at 6,150".

Solo (like me) or with others, this is a spectacular event. Enjoy!

This is not an out and back as the previous poster said. It is a good loop if you connect it with Ross lake.

This was a very beautiful trail offered breath taking views everyday of our trip. It is not the most used or maintained trail and is over grown in parts. I would also say that it is more than moderate, it was difficult trek in August with limited water sources.

Road is open (to Diablo lake at least)! Walked the trail today in the sunshine and it was magnificent. Hiked from the shared trailhead with the North Cascades Institute and turned around at the overlook to Ross Dam. There were about 3 small creeks that you had to hop some rocks over but they were very easy.
