A nice spot to start your hike at Huddart. Sorry if the coordinates aren't the best, dense tree cover here makes it hard to get it perfect. This one would be pretty tough without a hint, so here is where you can find the cache:
Start at the gate. Looking on the right side of the trail, you will pass a two trunked tree, then a large log, then a madrone. After the madrone, there will be 2 redwoods, one after the other. The cache is at the base of the 2nd one, next to a small/medium sized log, about 30 feet from the gate
