Alamosa trailhead is just west of the junction of FDR 250 and FDR 260. There is limited parking here. Trail 703 begins here and goes to Comstock Campground on Rock Creek. The trail climbs steeply out of the Alamosa canyon, then becomes easier after the top is reached. It intersects with Trail 704 near the top. The descent into Comstock Campground is not as steep as the Alamosa Canyon side. The trail is open to motorcycle riding, mountain biking, horseback riding, and hiking.
