From Colorado 160, east of Alamosa, turn north onto Colorado 150 toward Great Sand Dunes National Park. Drive over 3 miles and turn right onto Lake Como road (dirt). The type of vehicle you are driving will determine how high you can park on Lake Como road. Most cars can drive about 1.5 miles up before it gets rough. 4WD SUVs and trucks can slowly make it 3.25 miles to several pull-offs at 8,800’, before the road turns nasty. This is a popular parking spot and gets you within 4 miles of Lake Como. If you have a very high-clearance, small, 4WD vehicle, you can drive higher. An ATV or heavily-modified jeep/crawler can go to Lake Como.
