I did not see the comments beforehand... I should have read them!
Rode the climb eastbound after climbing Telegraph for a DC-Natl loop, definitely take the road to where it intersects with Holbert instead, becomes ridable again pretty much immediately after that (or just ride straight to BV Lookout). Otherwise it is rock steps and nasty stuff for days that are not easy to get up even with trials skills, unless literally not spending energy anywhere else that day and trying to clean this climb (maybe then? Maybe I should go back with my trials bike? hehe). Telegraph climb/HAB was a breeze by comparison
Looked like some fun rock rolls in a couple spots if headed downhill.

East bound Telegraph to Buena Vista…just take the road, the trail is unrideable.

I'll echo the recommended direction- east to west (downhill mostly). The other way (uphill) there's a lot of really high uphill steps that probably don't go unless you're a highly skilled trial rider, hence lots of hiking.
The downhill way was a blast. Some smooth. So chunk that all goes, definitely black. A couple really fast section with 2-3 foot drops with decent landings. Would recommend if you like chunk.
