Powers Garden trip over 3 days. We hiked up to Kennedy Saddle to camp the first night, down Corral Canyon to Rattlesnake Canyon and finally Powers Garden on the second day. Out on the Tortilla trail on the third day.
I'd say the Tortilla trail is the easier of the two trails to get to Powers Garden, but the views from Kennedy Saddle/Peak are awesome. It's a great place to go hiking.
