Do I need AWD for Snoqualmie Pass from SeaTac in winter?

Verified: 2026-05-30

Quick answer

Chains required WSDOT; AWD recommended not mandated

Detailed answer

Trend index **65** Nov–Mar ski intent. WSDOT R-1 chain law can apply on I-90; rental contracts require **$25–$45/day** AWD upgrade when available. Kayak SUV **$61/day** vs economy **$29/day**. Pickup at CONRAC **5–8–10–15 min** shuttle after baggage.

Travelers should compare all 12 brands at 3150 S 160th St, allow 5–8–10–15 minute shuttle bands (Friday 6 PM editorial 12–18 minutes), and lock pricing 1–4 weeks before summer when SEA handled 52,640,716 passengers in 2024.
