Going-to-the-Sun RoadCheck official access before departure: The alpine crossing closes seasonally. NPS says the full road does not usually open before late June and alpine sections typically close around the third Monday of October, sometimes earlier. Vehicles longer than 21 feet (including bumpers) or wider than 8 feet (including mirrors) are prohibited between Avalanche Creek and Rising Sun; vehicles over 10 feet high may have difficulty beneath rock overhangs. NPS says vehicle reservations are not required in 2026; entrance fees and all closures still apply. Check current NPS conditions and future-year rules separately. Untimed planned road trace.
