This is a fairly strenuous trail. It gets confusing because hardly any of the trailheads are properly marked. I lost sight of the trail when I rounded the first goblin cliff. There’s a point where the trail splits and goes to the goblin valley and goes further around the cliff. To get to the Goblin Lair, you have climb down maybe 10 or 15 feet of rock. Be careful because everything is sandy and the desert floor is far below. Once you’re past, there are, I guess, dunes of crusted sand that will crumble if you’re not careful. There may be easier way to get to the lair by climbing down to the desert floor and just walking there. The lair is basically an amphitheater of goblins. It’s worth the exhaustion.
