D1821 is a short, dead-end spur off the 7UP trail that leads past a few small campsites to a fantastic overlook of the Sevenmile Canyon area. The trail is rough, rocky, and slow, with a few 10" slickrock steps requiring careful tire placement for vehicles with smaller tires. The ending provides a nice campsite for one or two vehicles and views of 7 Mile Point, Merrimac Butte, and the La Sal Mountains. The trail is suitable for any high clearance 4-wheel drive vehicle.
