This is a typical route for me on my Bowhead RX, an adaptive mountain bike. I start at the gate off Perseverance Road. The gate is pretty narrow, so if your bike is wider than a Bowhead RX, you might have trouble getting through it (see photos). In that case, you can head to the Quarry Hill trailhead carpark and start there. There are a couple short but quick descents after you start the trail, one of which has a paved surface. Fair warning, if you go past this point, you may not get back up - it's steep. After that it's a climb to the ruins. From there, it's another easier climb south to the edge of the park. There's a sharp U-turn (see photos) at the top to get onto a brief bit of single track - a little skill is required. Then some more easy climbing, followed by some fun descents. Once you reach the crossover gate that goes onto Range Road South (see photos), you'll want to head out and take the road for a little bit. If you stay in the park, you'll reach a crossover gate with a very janky exit that's a bit risky. The road is much easier. After that it's fun all the way down. Turn off of Boehm Walk (see photos) to drop onto a little bit of Wednesday Loop (Virgin Valley). The transition is rocky and stepped, but pretty navigable if you're a confident rider. From there ride to the trailhead, and back up around to where you started.
