The end of the Confluence trail is at the dirt parking right across the bridge (next to a porterpotty). To get to the top of the tril, head alllll the way up the hill till you get to the top. At the top it will T, make a left, than an immediate left towrads the lake (forgot the name). It will be a small paved road, follow that. You'll see a small dirt parking lot (not much of a parking lot, about 5 cars can fit). That is where you start. When you go therough the gate, you can go 3 directions, go right up the hill. Keep going up the trail until you come to a big oak tree: That's where the DH starts. Just make sure when you see the first double go that direction: down the hill. The trail is easily to follow. You'll know you;re going the right way if you go under a massive culvert. It will take you to the road you came up on (the made road up the hill). Cross it and go staright across towards "Mammoth Bar". Take that for a little while, the last half of the trail starts on the right at a green horse gate. take that down to your car.
Sorry if that was confusing.
