I was suprised at the scenery and solitude of this hike. The River Trail parallels the Colorado River. I parked just ouside the fence. I hiked to the left along side the large man made ponds .. lots of nice ducks .. I kept going South on the narrow road to the River Trail trailhead. This tail is 3 miles each way, 6 total. The first mile has more dense trees. Then there is an interesting huge greenhouse with algae ponds. From here going West was when the hike got even better. To the right of the trail is a large natural pond with lots of birds. The trail curves some .. after about 1 1/2 miles the jeep road trail has a 'Y'. The right follows the power lines and left is very scenic. Lots of river views. On a sunny Saturday only saw 3 other people. Note: this park is closed at sunset with gate locked.
