A sign by the trail. It reads: Congratulations! You've made it to the 1/4 mark. That was the easy section. Now comes the hard part. The trail gets steeper and narrower from here. So, do an honest check in: Feeling tired already? Used up all your water? Light-headed or dizzy? This is the best place to turn around. Beyond this point, downhill travel is not allowed.
