You must see the Big Twigs, which is absolutely free. There are some signs up for Bobber and Oakley but not a sign easily seen for Happy.

Happy is located in wooded area behind playground area at campground. Easily access to all three. However, Happy is a little walk though. The trail to Happy may not be suitable for a stroller because it was a little muddy when we went and is little rough for stroller access. But definitely recommend going to park to see Big Twigs.
