Beautiful forest dipping down 800 feet in less than a mile to the river at a location with great skipping stones. Half hour down, hour or two back up. The terrain isn't technically difficult -- no rock climbing and it's a very wide trail (used to be a road) -- but it sure is exhausting going up. In the rainy season there are a lot of miniature waterfalls.

The old flume itself isn't that interesting -- just overgrown rock walls -- but the views on the rest of the trail are great. You can walk along the flume a bit but it quickly becomes overgrown.

Crowded on weekends, parking lot will fill midday on summer weekends, okay on weekdays.
