Some fun trails but lots of roots
I am a lower level intermediate rider. Surprisingly good conditions for January (had not rained heavily in 4+ days) with only a handful on standing water areas. Kudos to the trailer workers.
I hit Mainline, Lloyd's, Cedar Run, Ephemeral, Southern Traverse, Two Trees, and the Mountain Bike park. Cedar Run has some nice features (many too difficult for me) and I liked the twisty areas of the Mountain Bike park and some of the faster sections on Southern Traverse and Mainline. Lloyd's, Ephemeral, and much of Two Trees just have too many roots for my taste. Excellent for honing technical skills, but for me it felt more like work than fun getting through a lot of these sections.
Overall, some nice trails here but for my riding style Paradise Valley is probably not worth the drive compared to some of the other areas near Seattle. Still, it's a good winter option and definitely check it out for technical skill building.
