We had a spectacular hike today. Lots of people meant we passed someone every ten minutes or so depending on the trail. Other than a two inch piece of a glass bottle coming out of the ground in the middle of one of the trails, people respect the park extremely well. (And, yes, we dug it up and disposed of it because there are garbage cans in the bathrooms.) This was the first piece of garbage we found in three excursions here. The bathrooms ALWAYS need more attention, but you'll find the impressive trails and river beaches pristine and well groomed.
