I took this hike on August 17, 2018. The beginning temperature was 59° and sunny. When I completed the hike the temperature was 67° and sunny. I completed the hike as a loop ( which included the Iron Mountain Look Out, Cone Hill Trail and Tombstone Pass Trail ). As an added bonus on this hike, I was the only person on the 7.4 mile loop. Elevation gain was 1870 feet ( I went clockwise instead of counter clockwise ). The views were awesome. There was a slight haze from the fires down south, but every once in a while I could see the glaciers in the distance. The wildflowers were coming close to the end of their season, but there were still many varieties in bloom. I recommend this hike to anyone wanting to experience the best that Oregon has to offer! I had a great time!
