The trail leads from the parking area across the Mosquito Creek road and heads uphill north through an open pine forest with manzanita growing on dry slopes. The trail provides access to Alder Creek Falls a hidden gem within Yosemite's Wawona wilderness. I did the trail towards the end of February and as soon as you pass the fall the dense forest turns into a snow wonderland so waterproof boots and or clothes is recommended to continue north on the trail. Exact coordinates for the falls are as follows, 37.589660, -119.660483. Putting those coordinates in Google will get you there.

If you want to make this an overnight, you can learn more about permits here.
