The Snoqualmie Pass Nordic Center and surrounding ski area officially frowns on people sledding or inner tubing anywhere except at the sanctioned sledding & tow rope area, so be ready for (friendly) ski patrol folks asking you to move on if you’re anywhere around the parking lots or trails. However, there are nearby open areas with small runs that are great for little kids, beyond the nearby chalets and within quick walking distance.
