Good 2 hour loop with a fire road climb to start. Some downhill fire road, nice single track, tough downhill, and a couple tough climbs. A bit of everything.

    Steep on both sides (but less so on Palo Comado side). Overgrowth isn’t a concern but is a little dry and there are a few large ruts on the Palo Comado side of the ridge.

    Still overgrown on the Las Virgenes side of the ridge, quite tight and rutted, with multiple mustard plants sticking out at eye level

    Decently rutted but still very rideable, gets technical in the last half mile coming from Palo Comado canyon.

    Starting to get overgrown again. Still rideable, but you will be brushing up against mustard plants in places.
