Entiat River Orv Tr1400 is the easy Entiat River trail option, an Orv alternative to the N. Fork Entiat Tr1437.
Meadows Tr1404 runs a short distance to Myrtle Lake and adds a little variety to the otherwise straightforward OAB ride.
With the help of a shuttle, Entiat River Orv Tr1400 can be used as the return for a Duncan Hill Tr1434 to Anthem Creek Tr1435 loop (2400' 1.7mi descent).
Half of the 20.5mi loop is the 3400' ascent from the Entiat River Orv Tr1400 TH to the Duncan Hill Tr1434, with a 3200' ascent remaining if shuttling between trailheads.
For those seeking backcountry terrain, Shetipo Tr1429 and Three Creeks Tr1428 can be combined into a CCW loop, but be aware that these trails are not ridden very much so depending on the season may be unrideable.
Wilderness Hiking: Entiat River Tr1400 extends into the Glacier Peak Wilderness area, to the Entiat Glacier, with major backcountry hiking loops around Pomas Pass, Borealis Ridge and Spectacle Buttes.
