Did this as a day hike Memorial Day weekend 2018. More than doable in one day. Almost everyone on trail was backpacking. As expected a good amount of foot traffic on a holiday weekend but nothing compared to a national park. This hike is absolutely stunning. Everything you could ask for on a hike. Plenty of running water. Just be careful of the river/creek crossing. Will need some degree of balance to cross over a log. If you are camping over night there is tons of room at the lakes.
