californiagrownI'd suggest tokul. Tokul west is good fun single track with some free ride stuff, is a relatively short lap(1hour), and has maps available. Tokul east is more free ride but still super fun. And it is mtb in the traditional sense with free ride trails mixed in.
Regarding Tokul; it is currently closed due to fire hazard and does require a permit to ride there. Risk of trespassing charges are possible if riding without a permit.
The trails are completely worth it though. I'm hoping for some rain, which isn't in the forecast, so I can get back out there.
californiagrownHow is grand ridge? whenever i go to duthie im going because im feeling lazy haha fun singletrack or pretty meh with a fuck ton of climbing?
I'd ride Grand Ridge 11 times out of 10 over Duthie. More continuous ascents and descents, and tons of options for out and backs and one way trips. I prefer parking at Duthie and riding to I90 and mixing up with the trails near the retention pond and soccer fields. There are 3 total hills that drop down to I90 and it's nice to mix things up. Pretty easy to get 15-20 miles in with the out and back from Duthie. Good workout and worth checking out at least once. I'll show you around if you'd like.
byuboundNothing too techy, but pretty fast and a good time if you hit it at the right part of the day. Always go early in the morning or late if you want to go fast because its two way. Its rideable on an xc bike, but I enjoy it on my spartan.
Expect traffic on the weekends; it's inevitable. I ride there at least once a week and don't see too much traffic, but I ride mid-week mornings, or pretty early in the mornings on weekends. A 6" bike is overkill for Grand Ridge, but that doesn't mean it's not fun. I recently rode an X01 Nomad CC with Enve's on Grand Ridge which was complete overkill, but worth it. Most of my riding there is on my 150mm front/140mm rear Knolly, or my rigid fat bike.
Whatever you're willing to pedal up hill though, as long as it's worth it on the downhills.
