Dirtbike loop in Landers area close to same as dualsport loop but shorter no Ptown. Dualsport always provides more options, but I like riding my 300 2stroke too. Pioneertown is not a must do destination for me. It is a very hip place though. Very quiet on weekdays but lots of folks on a nice winter weekend day if the wind isn;t howling. Harley bikers, offroaders, ADV riders,musicians, hippie chicks, cowboys, tourists. You guys need to check it out.
You guys could dualsport to Joshua Tree NP if you had a mind to. Spectacular scenery, dirt roads only once off pavement. No trails. Very easy dualsporting, big bikes ok. There is a park entry fee. As an added bonus, the smell of good weed and pachouli oil in the campgrounds!
