"<p>Located just 8 miles NE of downtown San Diego, <u><a href='http://www.mtrp.org'>Mission Trails Regional Park</a></u> spans almost 5,800 acres and boasts over 40 miles of trails, making it one of the largest urban parks in the United States.</p> <p>While there are a number of trails limited to foot traffic only, a majority allow bicycle (and some horse) access. Terrain varies from mellow doubletrack to the NE of the park, to nice easy singletrack (SW), to the extreme at the North side of North Fortuna Mtn. Climbs in the middle of the park are steep - 450-500' in ~half a mile - and can be loose.</p> <p><b>Major Trail Summary:</b></p> <p><b>Father Junipero Serra Trail:</b>Paved road shared (1 lane traffic SW to NE only, 1 lane foot and bikes both ways) by vehicles and visitor traffic. Connects the visitors center area with Mission Dam (foot only, but beautiful) and Grasslands Loop trails as well as the campground.</p> <p><b>Grassland Loop:</b> Accessed from the Mast Blvd parking area in Santee, or from Grasslands Crossing from Father Junipero Serra Trail. Very mellow doubletrack - good for family outings with youngsters.</p> <p><b>Oak Grove Loop:</b> Trailheads are at the SW end of Fr Junipero Serra Trail, on the east side. Nice pleasant singletrack - good loop to add to a warmup ride, or for families with kids.</p> <p><b>Visitors Center Loop:</b> Mostly singletrack with some waterboards and 1 significant hill. Widens to the northwest and provides access to the San Diego River Crossing trail. This ford is closed when the water is up.</p> <p><b>Mariposa Gulch:</b>Connects the Grasslands loop with Fortuna Saddle and North perimeter trails. Hilly doubletrack but not all that steep.</p> <p><b>North Perimeter Trail:</b>Steep, loose doubletrack with large jagged rocks. Think bulldozer trail blasting straight no matter the terrain. Connects to the North end of North Fortuna and Shepherd Pond Loop from Mariposa Gulch.</p> <p><b>Fortuna Saddle Trail:</b> Steep at times doubletrack ranging from Mariposa Gulch to
