Directions from Camptonville: Travel on Hwy. #49 east for 12 miles to the Cal-Ida Road, which is on the left just past the Indian Valley Outpost. As you turn off, not the mileage on your vehicle for future reference. Proceed north on Cal-Ida Road. After 4.5 miles you will pass the old Cal-Ida Mill. Directly after the mill the road forks. Follow the right ford for 11.2 miles. The road is paved and has become Forest Road #25. You will pass Indian Fire area and the Eureka Diggins area. One mile past the Eureka Diggins Area the pavement ends. From the end of the pavement drive 2.5 miles to a point where the road forks. Take the left fork, staying on Road #25. After 1 mile Road #25 veers to the left. Stay on Road #25 (do not take Road #25-29). After 1.5 miles more the road forks again. Take the left fork, still Road #25 (do not take Road #25-31). Continue for 1.7 miles to the next fork. This time take the right fork (do no take Road #25-32, which leads to the Morristown Diggings). Driving the last 0.7 miles, you will reach the trailhead where there is ample parking in the roadside.
Very nice hike
It was a great and rewarding experience. The view was amazing and a good workout to boot.
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.

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.
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
Easy hike. This place is such an interesting thing to discover. My 7year old handled this hike with ease.
A little lost with climbing trails intersecting the main trail
So cool to see how the rocks formed. Sunny spot so bring water
Beautiful, easy hike!
The Devil's Postpile trail is an easy 1 mile RT along a river to what looks like square play-doh pushed up through the earth and twisted into rock - a very interesting columnar basalt formation created by volcanic activity and earth movements, similar to Sheepeater Cliffs in Yellowstone. There are fees for the National Monument... and annual park passes are accepted. For more of a challenge, go all the way to Rainbow (south) or Minaret Falls (north on John Muir/PCT trail). If you are in the area, don't miss this.
Amazing formation of the rocks can be very crowded at times but a must see. Great trout fishing along the river.
Beautiful. Interesting rock formations.
It was a calm hike to a very impressive geological site then hiked to rainbow falls instead of taking shuttle even took stairs to bottom of falls for a splash
