this route has not been ridden yet, In the planning stage, hoping to tackle it before summer heat sets in. I have been on most of the sections and the route "seems" doable. depending on time left in the day single track can be easily avoided and fire roads can be utilized.

    Santa Ana River Trail (2E03) - Morton Peak Section
    Dec 21, 2025 @ 5:12pm (America/Los_Angeles)
    Dec 21, 2025
    		Trail has no major obstacles, but is overgrown in some sections. Nothing you can't get through with speed. Only some soft/rutted sections near the middle.

    		1 major washout that is difficult to cross and 2 others that were easier. plus erosion throughout the trail. its an adventure to ride it right now but needs a lot of work
    Morton Ridge Road
    Oct 3, 2025 @ 1:02am (America/Los_Angeles)
    Oct 3, 2025
    		In good shape. Open while closure order is lapsed Oct 2025.
    Santa Ana River Trail (2E03) - Post Office Section
    Oct 2, 2025 @ 2:16am (America/Los_Angeles)
    Oct 2, 2025
    		Rode this section 10-1-25 from the Post Office toward Middle Control Rd. Upper part is mostly in good shape though brush is starting to come in. At the 3.45mi mark (1.2mi from MCR) there is a significant washout at a gully that is very sketchy to cross. I was able to cross without the bike but couldn't figure out a safe way to get the bike across as both hands were required. Might be possible but still difficult heading west. With two or more people bikes could be handed down and up. From that washout to MCR the trail is in poor shape with lots of erosion and two large trees down.
    Plunge Creek Truck Trail (1N21)
    Aug 27, 2024 @ 7:34pm
    Aug 27, 2024
    		Dusty and little loose with the occasional sandy spot with no major ruts or problem area. The first mile coming from Old City Creek Road is a bit overgrown but manageable. The turnoff from OCCR is covered in shotgun shells, glass, and all kinds of trash. The main descent of Plunge Creek was epic with tons of speed to be had with nicely cleared trail. It was over too fast!
