At just four miles roundtrip, Tin Mine is a nice year-round hike that features history and is kid-friendly. There are also lots of beaver ponds along the way and seasonal cascades as well.
At the back of the Gold Creek/Tin Mine parking lot is where the well-signed trail departs uphill through a second-growth forest. Not long after the trailhead there will be a connecter trail off to the left, this will take you down to the Gold Creek Trail. Keep right and continue uphill.
Shortly after the junction, there is a clear-cut area that is exposed. While this part of the hike isn’t all that great but you do get a great view of the eastern Olympic Mountains including Mount Elinor, The Brothers, and Mount Constance, and part of the Hood Canal on a clear day. You can also look down on nearby Tahuya Lake.
Continue uphill through the clear-cut area until you enter the forest again. This section has lots of seasonal cascades that are best viewed from November to May. Cross several streams on well-built bridges. Look down into a small valley to see a grassy Beaver Pond full of birdlife. This is a good place to go birdwatching for water-dwelling birds such as Red-Winged Blackbirds.
Just after the Beaver Pond overlook the mine entrance will be on your right. You are allowed to explore the mine if you wish. If you do choose to explore the mine then you need boots as the mine has standing water year-round. The mine goes back about 400 feet, with really cool stalactites and wooden posts supporting the mine tunnel. This mine dates back to 1895.
From here, you can either continue on to the nearby Lake Cherub or you can turn around the way you came.
