Went on the Green Peak Falls trail based on the positive feedback on this page, nice trail however would not recommend for smaller children. We hiked with our 3-year-old daughter and it was certainly challenging taking sharp, steep switchbacks and crawling over fallen logs. Older children should have fewer problems. Watch out for narrow trails with drop-offs. Dog did great and enjoyed the hiking, people practice good dog etiquette here.
The place was absolutely beautiful! I took my dogs and they loved it! However things aren't clearly marked to find where you want to go. I took a trail that was suposed to head towards a fall and it ended up being a dead end. Also many many people were there. It seems to be very well known and very well traveled.
It was very pretty I'm sure my wife and I will go again. It was confusing to find the green peak falls but well worth the confusion once you cross the bridge by Alsea falls you follow the trail until you pop out by a campsite you will walk down the road for a while after that keep an eye on the right side of the road and you a white sign that has seen better days pointing the way to green peak falls and there is a small trail marker just past the next campground to the right that starts that trail. My wife and I both lost cell signal once we got in the area so make sure you have any maps downloaded beforehand.
