A snow sled comprising a unitary body comprising a top portion having a seat portion, a bottom portion engageable with the snow, a rear portion, a front portion, and first and second side portions. The bottom portion and the top portion extend along a longitudinal axis substantially from the rear portion to the front portion. The top portion comprises a first wall portion. The lower portion comprises a second wall portion. The first wall portion of the top portion is spaced less than substantially four inches from the second wall portion of the bottom portion along said longitudinal axis. The top portion may further comprise first and second foot rest portions. The first and second foot rest portions comprise first and second wall portions.
