High Point

From the Mima Falls trailhead you can make several types of loops in a wide range of distances. The goal this day was to just ride the 4 primary sections out there.

There is only one I have a high direction preference and that is "Mima Falls West Rd to Rd" descent. It is simply way too fun for descending to waste it as a climb

So, I now always do this loop portion in CCW which means I climb "Greenline #6" on the north side of the loop on the way out during big routes like this one.

The rest of the loops out here I prefer in CW direction and there are certainly some sections that would just suck the opposite way due to the steepness or rooty sections.

Ok so maybe calling this trail mediocre was a bit unfair. This trail is quite decent and honestly with the length it’s actually a nice choice if you’re feeling something on the more long and mellow side. Even just one run down this makes for a fun day on a bike. If it wasn’t shuttle accessed it would be a different story though.

Very nice trail, when it’s wet still drivable but bring some extra clothes since it can be muddy

Definitely wouldn’t call this a mediocre trail. It’s a classic pnw XC trail that feels like you’re descending a mountain. Some lame climbing sections but lots of fun, fast downhills. Must ride if you’re shuttling. Along side little larch

This is in no way a black Diamond. Go ride the black diamonds at north slope and you’ll see what a black Diamond is. Honestly nothing on this trail is even that challenging. This is a pretty mediocre trail overall with a handful of fun technical sections. Little larch is a far superior trail.

Trail condition was good today. Dry and a little dusty in parts, but great in the woods. Leaves are starting to fall from the trees.

I think this is a challenging intermediate level course. A few pretty steep sections and tons of roots and small features to get a little air on. Rode this on our hardtails yesterday and had some root fatigue by the end for sure. Would be less challenging on a full-squish bike.

Not a black diamond i don't care what anyone says about that. It's a true blue and perfect for those trying to get more comfortable mtn biking. I'd say more classic than a flow trail but there's some fun berms and flowy sections. Do yourself a favor and ride the work roads or climb up to it...we came in awkwardly and rode up the last section to the top which was semi brutal.

Trail Crestline
Sucks there's no warning its closed for the last mile connecting to greenline. It was fun to ride and in good shape up to there. Not sure when they plan to reopen this!

Man this was sooo good! Super bummer there's no signs on the way that Crestline is closed coming in to greenline... that made a hard ride a lot harder going up green line to the start of it due to the wrong side of a 50/50 work road split decision...trails a little dry and loose but also grippy in spots currently.

I would say this trail is rated properly. I took a dated 2016 Trek EX8 29er down it and it was more than enough bike for this sometimes fast and flowery trail with some mild to moderate rock and root obstacles and maybe even a garden or two. The drops are small and don't sneak up on you. A couple of the switchbacks are tight if you come in too hot, but again, nothing you don't see coming.

Trail Crestline
Overgrown with nettles and thorny berry bushes at the top, but clears up pretty quick. Trail rode great a couple of days ago.

I would definitely call this a blue intermediate trail not a black diamond. There are roots and drops but the largest drop is maybe 15 inches and at the speed the trail provides it requires very minimal effort of the rider to compensate for the drop. I guess technically some of the drops are unavoidable but they are in the minority and are small.

Started at the Greenline Tie and there was a fair amount of snow there. Was able to ride it, but not much speed in the snowy areas. Once back in the trees it was good.
