Driving past the entrance to Nine Mile Cyn off CA Hwy 395 got me thinking about the potential for bikepacking in that area. Tons of moto trails up there, high elevation, water, meadows.
Any experience?
No recent experience!

I did do a camping trip up there, with motos, but that was more than 20 years ago. What I recall was lots of trails, right up to the wilderness boundaries. In fact, I met a guy who's passion was trout fishing. He'd moto up to the edge of the Golden Trout Wilderness, then day hike in to some remote streams for a day of catch and release.
Trails back then were good - some fire road, but lots of singletrack, not too many signs, so there was lots of route finding involved. That end of the Sierras is pretty interesting.
I can't recall the name of the place we camped, but it was a forest service campground, in past Kennedy Meadows, and at a higher elevation, so more forested and cooler
