"The Hamilton Pool, this beautiful collapsed grotto, is a perfect place to go when needing to chill in some cold water. Linger in the pool andenjoy the clouds gliding across the sky and the cooling sight of water trickling down from the trees andlimestone roof ledge. It's a shortbut slightly ruggedtrailfrom the parking area down to the Hamilton Pool, and from there you can hike to other lakes. But be advised:The pool is limited to 20 people, and most mornings there's a line of 10 cars waiting to get in before the gates open at 9 a.m. (Call before you head out to be sure that the trail and poolare open, especially after heavy rain.)"
