The spillway is one of our new favorite locations! Don't specifically listen to the reviewers that are complaining about the level of water on the specific day that they went because it changes. It had actually been flooded for a while up until a couple of weeks before we went. Thankfully, because of that, it was manageable to hike up through the water since the levels decreased. Otherwise, you have to hike completely around the spillway, which can be difficult. Main tip, wear anti-slip shoes as there are some pretty slick places. Overall, we absolutely loved it.
