Cattywampus starts up by the lookout bench along the Swamp Donkey
Trail; however, another easy access point comes straight off Center Trail
, the access trail, that leads down to the reservoir. It's marked by a small orange irrigation flag on the south side. This trail doesn't have a lot of technical riding and you end up right on the shore. Follow it along to the base of Swamp Donkey
, which is a great climb out of the ditch. Look for the "Bike Up" signs nailed to the trees along the way.
