The Fairbank trails should perhaps be considered a network instead of a loop configuration. You can ride the outer loop as described but the trail from the junction with the trail into the dry wash to the railroad bridge is very sandy. The parts that are firm are a really fun single track but a lot of the trail is a bike push even with very low tire pressure. Concerning the dry wash trail that connects with the Presideo trail. It is not really a trail at all. It is possible to get to the Presideo trail but it is very difficult and you will be sorry you brought your mountain bike along for much of it. I mapped it and the following instructions will help if you decide to try this on your own. The day I crossed the San Pedro river bed it was completely dry so that was no problem. Cross right where the big wash meets up with the river. On the far bank make your way North and West. You need to get up on the high bluff and connect with the abandoned railroad bed there. The easiest place is about 1/4 mile North. Once on this bed you need to come back South to a black post on the West side of the railroad bed right next to a sign with the number "17" on it. From here push through the bushes uphill a short distance to the West. You'll soon see the traces of an overgrown double track jeep road heading Northwest. Follow that up the hill to the intersection with the Western abandoned railroad bed near the Presideo. This is the Presideo trail at a point just South of the Presideo loop (see the Presideo Loop Trail). This "trail was just included because it is listed as possible on a trail sign and to tie this trail in with the Northern trails.
