only thing hard on this trail is finding a fun offroad obstacle haha. smooth all the way to the parking lot where i found a honda accord had completed the trail i aired down for. there is one steep hill thats pretty long but pretty typical driveway in the foothills. at the end parking lot there is a gate and it seems to stop you about 90% of the way through the trail listed on alltrails. it does appear that the trail gets harder just after the gate but it can't be very long. anyway, very nice views of gross coming in, nice mountain views from up there and an easy trail that can be completed in just about anything. if you'd like to see some clips of this trail to get a feel or check out the other gross trail i have a video up at:

Stock Tacoma in the dark. Definitely not a hard trail. Moderate. Fun though, will go back when it snows.

A very driveable campable trail that has some nice vistas and great access to Gross reservoir, we saw some hummingbirds, snakes and fish, overall driveable even wet in a stock 4x4, in low range.

Real fun. Not the easiest run but still very doable with a stock jk rubicon. Wouldn't do it in anything smaller. Not a lot to look at on trail. More of a fun off road trail to ride.
