But now this park is a popular destination for those wishing to immerse themselves in a thriving forest or enjoy the natural water slides along Linn Run.
Adam Falls would be lovely in the spring, after rains, but in July, it was a very thin stream of water, a dripple, really, comparable with what you get when you turn on the kitchen faucet. But we enjoyed seeing the grotto behind the falls before climbing back up to the trail.
The trail then became very rocky but lovely with the floor cover of leafy green ferns. We missed them, but apparently there are chimneys and foundations of old cabins along this trail.
This is not a long trail, so you'll likely have time to check out the Flat Rock Trail, a half-mile out-and-back trail that leads you along Linn Run, past the ruins of an old cabin that offers a fun detour to imagine what the rooms once looked like.
Bring water shoes and get your feet wet -- the stream is inviting. And the smooth rocks form a natural water slide, which, on the day we were visited, some kids were enjoying, shrieking with delight in the hot summer day.
