Some details of the geologic origin of the Devils Postpile are not completely clear, but enough is known to reconstruct much of the story. Until recently, it was thought to have formed about one million years ago. Current studies suggest that the Postpile was formed less than 100,000 years ago when a cooling lava flow cracked into multi-sided columns. However, to fully understand the geologic setting of the Postpile we must go back millions of years to a time when there was no Sierra Nevada and California was a shallow sea. The beginning of North America For nearly 500 million years, what is now Eastern California was a shallow sea. The western edge of North America was several hundred miles east of the present coastline and North America was part of a large super-continent called Pangaea. This super-continent was the land mass from which all of today

Beautiful falls! The actual hike to the falls is relatively flat and family friendly. Be careful if you have little ones wading into the water near the falls; the rocks can be very sharp!

Very nice hike

Went here after the Devil's Postpile, it was a nice trail and offered some more amazing views once you got to the waterfall

It was a great and rewarding experience. The view was amazing and a good workout to boot.

Amazing hike, it never gets old!! It's super smart to go very early in the morning around 5am so that you yourself can drive down there and park wherever you want. I have taken the bus down there and i had to stand the whole time and quite frankly, i think any Californians or hikers will admit that having to stand in a packed bus isn't our cup of tea and we're not used to it. Also there are MANY tourists that you can avoid as well. Get up super early when it's still dark and drive down to Devils Postpile and catch the trail. You have to be at the entrance before, i believe, 7am or else they will not let you in! At this early in the morning, you can't see the rainbow at the falls because the sun doesn't hit it yet, but it is worth it. You might see one or two people, and it is so calming. Birds chirping and the sun rising, nothing beats it. This is amazing compared to the hundreds of people trying to get a peak at the waterfall, and hundreds of people on the trail alone. But whatever you end up doing, enjoy the whole experience!

Beautiful hike with nice views. Waterfall had a good amount of water and we even saw a rainbow. We walked over the top of Devil's Postpile which offered more views and a closeup look on the hexagon patterns. Total distance including hike back along the road was 5.9miles

Easy stroll for the average person. We hiked here off of the PCT as a quick detour. Crowded ... But beautiful.

We went in the evening, after 7pm, when you didn't have to take bus anymore and could just drive down the parking, right next to the Devil's Postpile. This way we were almost completely alone on the trail and were able to marvel at the monument in relative solitude.

During the day it's possible to take the bus to the Devil's Postpile stop and then it's only 0.5 miles to the sight, a little more if you want to go on top and see the hexagon squares on the surface.

Probably more spectacular earlier in the summer, but the trail was great for my husband, dogs & me! The falls we're still nice, just not as full as the photos I've seen and no rainbow.

The scenery going to the falls is outstanding! We decided to connect to the Pacific Crest Trail and get off the beaten path on our way back to the falls, which was well worth it. The trail going back to the bus stop is all up hill so caution should be taken for people with health conditions.
Over all I think it is worth going to see.

Nice family trail. Always very crowded. Still very beautiful and great for kids.

Nice trail. Easy and almost flat. The waterfall is gorgeous. Mind the sun in summer - not a lot of shadows towards the fall.

This was a beautiful breath-taking hike. This time of the year was perfect since it was not too hot or cool. We took the trail also to Rainbow Falls. There was some steep hills to climb but overall it was a moderate hike.

In summer you can climb up the falls!

Go in the morning to beat the heat of summer, but go in the afternoon light if you want to see beautiful colors on the monument and rainbows in the falls

We only did the hike from Red's, Easy hike from there, although trees are burnt out from forest fire years earlier, could get warm mid-day, Stairs to the bottom of the falls were closed, wish we would have known, would given a higher rating if we could have gotten down to the river!
