The campground on the Boulder is Springcreek campground. Nice enough place. The Boulder can be a great creek if the fish are in the mood and it isn't too high or low (trout can get heat stressed). As someone else pointed out, there are numerous access points along the Boulder. A couple of interesting side notes about Springcreek campground. They used to raise trout (don't know if they still do) and had ponds for fishing that were pay by the pound. Be very careful, because if they still have them you can run up a very big bill, very quickly. Waters just below the campground used to be some of the best big trout waters for miles. The reason was a local game packer used that spot to dump the carcass waste. It was dinner on for the trout and they grew huge. The environmental concerns put that to rest a long time ago, however. Now you have to catch them sportingly, so to speak.
