We did a 2 night backpacking trip along the Hoh River Trail. We decided stay 2 nights at Olympus since there was still snow pack up the mountain. We hiked in 10 miles the first day and the next day we left out stuff at our campsite and hiked up to Elk Lake and back.

The sites at Olympus are pretty spread out and include a couple group sites. There are also plenty of great spots for hammocks. They do have 2 composting toilets (one was full) which is all you can hope for when you are backpacking. The trip overall was fantastic and I highly recommend it!
