Cleo's Nature Trail
Head toward Melba- take 12th till it turns into 45
When it starts to curve left toward Melba, stay right and you will drop down to the bridge over the Snake River
Don't go across the bridge though
Just to the right of the store/gas station is a sign for the museum
It's a dirt road- head down it and turn left into the gate
Enjoy the walking trail and peacocks and lulling river
It's free!
