Beautiful trail!

First time up on Rattlesnake Mountain. Power was out at home from the wind storm, so decided on a quick hike up to Grand Prospect. A little bit of snow close to the Grand Prospect, but nothing needed for traction. The trail is a nice gradual trail up, so not real hard on the knees. I'll be back again this winter for the whole traverse down to Rattlesnake Ridge and the lake.

Challenging, but in a fun way. On the crest, it is exposed to the south/west, so the bitter wind and sleet can put a damper on the journey. But, still highly recommend this trail. Stopped at Stan's Overlook and Grand Prospect areas but couldn't see much with the cloud cover unfortunately.

Not recommend. Although it's a well-marked trail, there are a lot of burned areas blocking the way. The trail is too narrow, so we stopped many times to make way for biker. And the view of the top was disappointing, good for biking but not for hiking.

This time the weather was really clear (9/7/18) and I was able to see Rainier and the valleys very well. Between miles 5 and 6. It was a pleasant surprise because every time I have hiked here it has been cloudy so I didn’t even know there was a view of Rainier. :-) Well, there is, and it’s magnificent. There is a lot of clear cutting at the top of the mountain, but that allows you to see some really great views.

Today I continued down the trail to the Ledge then returned back the way I came. Including some extemporaneous exploration, I logged 18 miles and 4500 elevation gain.

Great hike! Definitely recommend!

Well marked trail, great forest terrain. There are some burned areas to get through, and the top is a little disappointing with no viewpoint and lots of logging. I went through to Rattlesnake Lake and it was very cool, also shorter than turning around and going back down.

The trail is very well-maintained and the signs are regularly and clearly marked so you won’t have trouble staying on track. It is a steady incline throughout, with very forgiving intermittent flat/downhill patches. Overall, I really don’t agree with the “hard” rating. It is more moderate.

There are beautiful views at miles 2, 4, and 6. In June all the wildflowers are in bloom, making the trail exquisitely beautiful. All the snow is gone by now and there were only a couple of small muddy patches, which were very easy to navigate around.

Most people comment on the high traffic of this trail. It is no lie. Going early on a midweek day is your best bet. I went on a Friday morning at 5:15am and I was the only one on the trail all the way to the top (and some birds and a few unfortunate snails). However, on my descent (shortly before 8) I began passing other hikers on their way up. Even still, it did not feel congested at all.

There are quite a few viewpoints along the way with benches. I brought breakfast and a great book and had a wonderful time enjoying the view at the top, eating breakfast, drinking my tea, and reading the book.

I highly recommend this trail! If you go outside of crowd-time, this is a great trail for relaxing you-time. Have fun!

Trail is in great condition, but beyond Prospect Point there is still a little snow on the trail, but not bad. Trail is more intermediate than hard, a steady grade up and down. Mostly in tree cover, with occasional clearings for views. Ate a snack while enjoying the view of Si and her sister peaks across the way.

Trail is in great shape for this early. Ran into snow at the creek and again about a half mile short of Prospect, but it was easily navigable with hiking shoes and poles. Snow was about 2 feet deep at Prospect.

I hiked Rattlesnake Mountain but went until Rattlesnake Ledge to get a view (but weather was too bad). We only met 4 people on our way. It was windy on the part that goes along the ridge and snow was deep. Snowshoes would have made things much easier. After a 15 minutes break on the Ledge we went back and our footprints had already disappeared along the ridge. The hike was wonderful considering it was snow covered.

The hike is a little strenuous, but definitely does not deserve the hard rating it is given. The views are pretty good from the main lookout points, but even early/late in the day there are such an unbelievable number of people it completely ruins it. The planned 'deforestation' near the summit is awful. They tore the place up terribly, and left it a real mess. The summit itself is still accessible, but through a graded logging road, and this steals the allure of it right away. You can however see Rainier pretty well from this higher logging road, but this is the best view you'll get because even the summit doesn't give you a clear view. If you're looking for a great hike close to the city, look past this one for lesser-trafficked routes. The upper section past all the lookouts is less crowded, but having to elbow your way past throngs of people on your way out (if you get in early to beat the rush) is no way to enjoy nature.

I really like this hike. Very quiet, peaceful, and go as far as you want. Do 2 miles to the first view, do 6 miles to an even better view, or do the whole 10 miles and soak in every bit of it.

Everything was open to East Peak but there are a few downed trees past the ridges. The first couple of miles can be crowded with trail-clogging tourists and families but the views on the cliffs are worth it!

2.5 stars. The final leg is still closed. Until that happens there is no payoff on this hike. It was challenging and great exercise with nothing to see. I will update the next time I return and I get to finish what is the point of the whole hike.

Good workout. Gain is my max as there are few places where the trail is flat. View at Grand Prospect. Logging has been going on around that area, so it's unclear if you can continue from there. Parts of the trail have overgrown vegetation, and since I don't know my poison ivy and oak from anything I tried to stay clear. You'll still get some sun, so load up on sunscreen.

Awesome trail! Not as hard as it's made out to be, I went up in February and could not even finish the hike because the snow at the top was so bad and had destroyed the trail. But amazing during the summer

Very fun day hike with good variation of scenery. Good and steady ascent but very long so stay well hydrated.

Moderately difficult, good ups and downs, rewarding view

5/23/2017 (Tuesday) -- Sunny, cloudless, 72-76F in the woods, 80+F in city. Cool, not hot in the woody trail. Light traffic. Trail is in good condition. Mud and snow are gone. Downfalls are partly cleared. On the logging road as a detour, Mt Rainier is fully in sight.

Great route either starting from the west or east if you are smart about times to avoid the crowds. Trail is soft ground for the most part, well shaded, and great lookout stops along the way. Creek at about mile three (coming from the west) is flowing strong right now for any dog companion folks out there.

Note that as of 5/14 the trail is closed at Prospect Overlook due to timber industry work so cannot connect end to end at the moment. Check their website before attempting to cross through to see whether it has reopened. I ran this and still got a good ~8 mile out and back despite the closure.

It's very nice hiking trail where I used to go there often. I like it!

It's really not a difficult hike, I think it should be rated as moderate, it's just long. There were lots of downed trees that caused some difficulty as they're not tall enough to go under not short enough to go over. The snow/ice is also so deep this time of year and it was like walking on eggshells trying not to sink. Twice I stepped just a little off the trail and ended up waist deep in snow! My dog wiped out a couple times running and one leg sinking, causing her to trip. Kind of fun, added an element of alertness for the both of us. Payout at the end isn't much, but we didn't see anyone the whole way up or down so the quiet was nice. I probably won't do this one again anytime soon though.

Hiked this trail today. It was really great to go from no-snow to real winter snow in a not-too-long distance, and nothing steep - did not need to wear spikes. Very enjoyable. Not crowded, but did not feel totally alone, which is re-assuring.

Hiked this the day after the "big" wind storm. We got about 1/4 mile past prospect and ran into a number of large trees uprooted and across the trail. Climbed over a few then decided to turn back. Only saw a handful of other people on the trail. It's a nice steady hike on a smooth trail.

It was difficult enough but it is wayyy too crowded. I like to go to the woods to get away from people.

love the sound of creek.

Came back since I missed the summit last time. Unless you like seeing acres of twisted stumps and dead branches where the lumber industry has left its mark...or like radio towers...there really are MUCH better hikes along I-90.

Good hike. Went to east peak and turned around. Some awesome views when the fog started to burn off. There weren't many people on the way up and a bunch at the first look out and the rest of the way down. Part of the trail is new and it runs through where the logging project was. A nice log bench to sit on in the middle. If my uncle didn't want to stop and talk as much I would have pushed for the lake.
