The first step is to go through the first section of the trial, until you’re at the first exit. There is no way to skip this that I know of, but there are none of the shadow creatures in this section, so it shouldn’t be too difficult. Eventually, you’ll reach this ramp at the end:

Instead of going up this ramp as usual, look a bit to the right, where there’s a space in the wall. Go into this gap and then spam jump up the left side of it.

Once you reach the top, go forward until you’re on the rock sharply pointing out.

Across from the rock you’re on is a ledge that you’ll have to jump onto. This jump is a bit difficult, so you might have to try multiple times. I find it helpful to jump a few more times while I’m in the air, in order to jump onto the ledge if I miss it slightly. The ledge should be in the general location of the circle here:

Don’t be discouraged if it takes many tries! It gets much easier with practice.

Once you’re there, jump on this rock to the right. Go carefully, it’s easy to fall off again!

After that, all you need to do is carefully walk forward until you reach the crack in the rock I’ve shown in the picture. Then, spam jump to the top.
