We’ve been to another State Park this Sunday. It was great, we hiked the whole day and got totally lost in the wilderness (there were deer paths that looked like human paths :)). The waterfall is really ridiculous (see picture), but the wolf cave is really cool.
It’s a small (very small) tunnel-like cave where one can go (crawl) through. It’s not really advertised on the webpage (I guess they are afraid that some people just get stuck in the middle – this nearly happened to me as I realized that my shoulders are to wide for several passages in there :)).
