El Vado Lake State Park is both pleasant and gorgeous, and it's in the neighborhood of Heron Reservoir, and after a long day outdoors Best Western Jicarilla Inn & Casino is a great spot to spend a night or two. A close by type I-III whitewater part can be encountered on Rio Chama; the El Vado Lake to Abiquiu Reservoir segment is 33 miles long.
