Barking Dog is a fun natural standing wave on the South Fork American River near Coloma, shaped entirely by the river rather than any engineer. Access is the real story here—private property lines the banks on all sides, and Camp Lotus is typically the only landowner willing to let surfers cross through to reach it. It comes in during spring and early-summer runoff and carries an advanced rating, so it's not the place to learn to surf. Be a good guest if you go: respect the property, keep it low-key, and don't burn the access for everyone else.
