This the hardest and most remote section of the Timothy Lake Loop
. Timothy Bike Trail #537 was once called the Old 1916 Trail. It connects the Headwaters Trail #522
and Timothy Lake Trail #528
and travels east of Timothy Lake and parallels the Pacific Crest Trail #2000. The trail is more technically difficult than the rest of the Timothy Lake Loop
and offers more challenge. You'll find some longer climbs and some features throughout this section. Additionally, it's more remote than every other section, but you'll still encounter the horse groups and bikers, so be on the lookout. Also use the Trail Run Project mobile app
and pay attention to signs as there are numerous logging roads that can take you off trail.
There are some really nice smooth, rolling sections at the western end depending on your direction of travel. They make for a nice climb if heading clockwise. Good free parking can be found at the eastern end of this trail off the side of the road.
The actual connection trail between this and the Timothy Lake Trail #528
is via the Pacific Crest Trail. It's over a marsh and is very well marked.
