As per COTA and the USFS, Tiddlywinks is a two-way mountain biking trail, but be careful and aware when climbing. Make sure to look ahead for riders coming downhill — especially in the newly re-worked middle “flow” section where descending riders will likely be going very fast and lines of sight are somewhat limited.
Tiddlywinks starts out at Wanoga Snow Park and is a little more flow-oriented than Funner, with less rock and more berms and jumps along the middle section. The top section of Tiddly is more XC style trail and rides out through some open, rolling terrain with some rock gardens, and then intersects Kiwa Butte trail.
After the intersection with Kiwa, the trail heads down through some heavy berms and flow style jumps on the order of Lower Whoops trail. COTA has invested a lot of time in converting this old road section on the trail to something really dynamic. The guys at Oregon Enduro invest a lot of time on this trail as well.
Along the upper-middle section there is a separate up route for those who are climbing.
