It's an short, easy hike to from the parking lot to the Postpile. The additional moderate hike to Rainbow Falls is well worth ti if you are so inclined especially in early to mid spring when there';s plenty of water coming through.

The postpile itself, is quite impressive and I enjoyed taking a walk all over it, and spending some time overlooking the river from the bridge. ... thinking what a huge loss a small amount of dynamite could have caused.

A spectacular formation of rock, that gives a real insight to the wonders of volcanic activity. Nicely laid out and plenty of information points. A little hike from the bus stop. I saw a couple of very obese people who were struggling with the incline, heat and 1/2 mile walk.

A must see for Mammoth, and it looks just like The Giant's Causeway in Ireland, with 1/10th of the tourists.
