The highest mountain in the Elk range with a fun permanent snow field. From the parking lot hike up into the basin across the snow fields. The easiest route is to stay on the left side of the basin and do an ascending traverse along the snow. When you enter the basin that is just below Castle Peaks summit look to your left and you will see a strong trail that leads to Castles NE ridge. Take this trail to the ridge, then follow the ridge proper the rest of the way to the summit. Several trails lead off to one side or the other of the ridge that appear easier at first, don't be fooled stay on the top of the ridge.

Did a combined trail of Conundrum and Castle Peak. More technical than I was expecting (narrow ledges and scrambling). There was a lot of loose dirt and rock, which made it difficult to hike without slipping. However, there was a huge snowpack we slid down to cut off some mileage, which was amazing. Definitely worth it to bag two 14ers.
