Features -none-


This trail a NEW local favorite. This loop gets it done and is the easiest option to climbing back up. There are many other options to this loop. This area has a vast amount of trails, go explore!

This trail was newly built and completed in 2013 as a joint project with the FTA and BONC. This is a true masterpiece of trail engineering. It has twisty banked g-outs, tabletop kickers, log and rock ride options, and such perfect flow it's unreal!! Very few tech sections, and not much cliff hugging. This smooth trail is packed down, but gets a bit chewed up after summer from all the traffic.

Need to Know

Riding back up the road in the summer season, on a weekend, can be a deadly proposition due to lake-going boaters that have big monster trucks and water craft trailers. Alternate route recommended.


From the Harmony Market hub parking, cross over the highway and pick up the paralleling trail on the roads shoulder on the east edge of the 5 Mile House parking lot. After a short flat roadside section you'll see the trailhead sign and the trail goes to the right and the fun begins. The trail starts out flat but after crossing a small private road, it is ON!!! Once your brain has been scrambled from a phenomenal downhill, you pop out on Casci Ranch Road. From here you have some choices, go up Casci, or back up the trail (ugh). To continue cross over and continue down to the lake.

The lakeside section on Scott's Flat Lake Trail is a perfect finish to a sweet downhill, it meanders along the shoreline with several places to hop in for a swim, or just catch some rays... When you get to the dam, that's the end of the line. Return the way you came, or climb up through the campgrounds and back to Hwy 20 on Scott's Flat Road.

Once you get through Scott's Flat Campground via the lake front trail segment, turn left and head up Scott's Flat Rd. The road gradually climbs back up the ridge, wraps around and takes you right back to Five Mile House/ Harmony Ridge Market hub.
