Peeler Park
It’s not clear how long you can remain camped at Peeler Park; the Water District has not published any such rule. You probably won’t want to stay here too long due to the limited amenities and the not-so-great cellular signal.
On the other hand, the parking lot is pretty level, and is all paved. Not many locals visit Peeler Park which means you can expect a lot of peace and quiet through the night.
Peeler Park is also great place to launch your kayak to explore the twisting water ways that extend from the southern point of Hubbard Creek Reservoir.
