We arrived early and there were absolutely no cars in the parking lot!
This is a nicely, well marked trail. It took us about two hours to complete the loop with a short 10 minute break at the top. We took Oxen Bow Trail on the way back (highly recommend).
There is a steady incline for the first mile or so but well worth it for the fantastic views at the top! There was also a nice amount of shade on the way back which helped in the summer heat.
