Devils Postpile National Monument

It's such a beautiful place. We had to drive a very scary road to get there. Then we had to hike about half a mile. It was not bad at all, but it's just uneven grounds. Thank God for the bathrooms. You can also see the posts from the top. Which we didn't do because I had to run back to the bathroom. Maybe next time. Lol

Very unique rock formation with an easy accessible hike. The columns continue around the entire loop and you can see varying perspectives, which is very cool. Highly recommend doing the loop - easy hike.

Super nice! It's definitely worth the drive to see it! Highly recommend it!
There is a long drive from the national park entrance to get to the beginning of this hike. About 35-40 minutes. Once you get there, there is plenty of parking and a couple of portable restroos. Once you start the hike, in about 15-20, you'll get to the Devils Postpile area. There are a couple of waterfalls you can hike to as well.

I loved it. Super easy to hike around. Lots of shade so it keeps the area nice n cool. Don't get me wrong, you will feel the heat after an hour of hiking. The water is very cold but it looks super clean as it us very clear. Lots of easy was to hike to different destinations. But going up to the top of the post pile is quite challenging.

The site is very educational. If you don’t have time to visit Devils Tower in Wyoming, you can visit here instead. Usually, people spend time in the bottom of the post-piles. There is a trail to the top. It is not hard and in the end, you can see all cool hexagons of piles.

*open on weekends only* Beautiful nature occurrence. Can't explain, just admire. Definitely recommend to visit, and walk the surrounding trails. Rainbow Falls is a must see.

The trail is highly accessible and fairly easy. Interesting rock formations. Clean area and restrooms around. Limited parking. You can hike to rainbow falls from the trail. Challenging hike. There are shuttles that go around but not sure about the path or where they stop. Did not see any around. Worth to stop by and go. Worth the hike.

This place is nothing short of spectacular! Nice, easy hikes? ✅ Breathtaking views? ✅ No crowds? ✅ Spend a night or two on local campgrounds for a full experience, just make sure you're prepared for every weather.

Amazing geological wonder that is accessible by a short, easy and dog friendly hike to the base of the postpiles from the Rangers station! The hike to the top of the post piles is a short moderate hike but worth it. You can also choose to continue the hike for another 4 miles (round trip from the postpiles) to visit the beautiful rainbow falls!

It’s best to get in before 7 am to beat the crowds and also to avoid using the mandatory shuttle bus from the Mammoth Mountain Adventure Center (costs $15 per person and there is a long wait to hop on a shuttle). The road to the ranger station is very narrow and windy. There is ample parking and restrooms.

So beautiful! Watch out for the shuttle bus. It’s best to get in before 7am in order to not have to use the shuttle bus. It’s dog friendly, easy-ish hike, and very beautiful views.

Amazing, beautiful, spiritual! Be in the park before 7am to drive straight to the trail head. Any later then that and you have to park below Mammoth and walk up to get a shuttle to the trail head. Tickets for the shuttle are purchased in the shop at Mammoth resort, the activities area. $15 per person for the shuttle. There are also ziplines and practice sluice box where kids can buy a bag of dirt with gems in it. Best birthday ever!

Fascinating and beautiful place! Highly recommend going by shuttle and letting a professional do that mountain driving, which is one lane in places. I also recommend taking the first shuttle at 7:30am. We were able to spend a few hours there with not too many people around. When we headed back to the shuttle stop we saw a lot more people and even more back at Mammoth Mountain waiting for the next shuttle. The shuttle ride takes about 30 minutes, and there are flushing toilets near where the bus drops you off.

It’s worth it to hike to the top of the pile to see the tops of the columns. We couldn’t figure out where the loop trail goes to get to the far side of the pile, so we just went back the way we came and continued exploring the base of the pile.

I find it so interesting to see how a volcanic eruption and subsequent pyroclastic flow turned into these amazing columns that cracked perfectly into hexagonal columns. It's a pretty easy trail to the bottom that gets moderately more difficult up to the top.

short hike. not busy at all on a fall weekend. cute little booth at the ranger's station for kids and families. ranger walks in the morning. no cell service

Getting there before 7 am meant we could drive all the way to the parking lot at the Rainbow Falls Trailhead. From there, it's a relatively easy hike (downhill going and uphill coming back) to falls. But I also recommend continuing downhill to the Lower Falls, where the river takes a major turn. It doesn't attract as many people, and it has plenty off-trail opportunities to explore.

this is an awesome place a must visit if your in the area gorgeous rainbow waterfall is close by

Awe-inspiring cliffs of geological formation, delightful short walk through the trail. Dogs are allowed on the trail (on-leash).

This was a great choice for our 5 kids. It was a short hike 0.4m, and not too challenging. We were able to take the jogging stroller with only one area where tree roots made it a little difficult to get past. The monument itself is amazing. There is a challenging and not stroller friendly climb to get to the top and see the hexagon tops of the basalt formations.

A must see! We visited while the shuttle was not running and the parking lots can fill up quickly. The drive down is a bit scary but doable! Thankful to the park for using the campgrounds as extra parking.

The Devils Postpile loop is a little taxing but short, and well worth it. We also hiked to the Rainbow Falls viewpoint. Take water and use sunscreen! The walk is roughly 2.5 miles and I couldn’t believe the amount of parents with kids with no supplies! Lots of sun and it’s warm!

I found it fascinating that the John Muir Trail and Pacific Crest Trail passed through this area. We decided to hike this trail north to get back to the ranger station. I cannot recommend this enough! Beautiful views and NO people. There were throngs of people on the Devils Postpile Loop and Rainbow Falls Trail.

Beautiful place!! Could easily spend a whole day there checking out all the sites. Short hike to the devil's postpile monument, about a quarter of a mile. About the same to get to the top, but all uphill. To rainbow falls is 2.7 miles. Great scenery! The parking lot area is pretty small. They have restrooms there, but limited amount. Not very clean, but still work! The drive up there is really nice, have camera ready. The road up is a narrow windy road. There's a fee to enter the reds meadows valley.
