HZ Wash had 1 defined parking area and another dirt road that could take you to some campsites. There is a bathroom building in the parking lot as well as shoreline access but it is posted 4 wheel drive vehicles only. HZ Wash has a good view of the Diversion Dam and is directly across the River from the Diversion Dam camping area. If you do take the dirt road to a campsite it gains in elevation and you will have to find a path and hike down the canyon side to get to the water.
