Khanh Le Pass Closure Rerouting & Rescheduling Policy: Practical Field & Routing Guide

During the Eastern Truong Son monsoon season from October to December, Khanh Le Pass on National Highway 27C (reaching a summit elevation of 1,700m at Hon Giao peak across about 30 km of mountain road) occasionally enforces nighttime traffic restrictions or temporary daytime barrier closures to clear rockfalls. For travellers holding confirmed hotel reservations in both coastal Nha Trang and highland Da Lat, knowing how your private car service handles highway rerouting and schedule changes ensures peace of mind.

Sun Travel operates well-maintained 4, 7, and 16-seat vehicles with friendly local drivers under a transparent mountain safety policy: we recommend crossing Khanh Le Pass during daytime hours, proactively monitor pass closures during heavy fog in the October–December rainy season to advise rerouting via National Highway 27 (Ngoan Muc Pass / Phan Rang), and move your departure when the weather rules out the pass; rescheduling and cancellation follow the Trip terms on the route page.

Standard Rerouting Protocol via National Highway 27 (Ngoan Muc Pass) During Pass Closures

Overland transfers linking the coastal centre in Nha Trang Ward, Khanh Hoa Province with the highland centre in Xuan Huong - Da Lat Ward, Lam Dong Province rely on two main national highways. Whenever National Highway 27C over Khanh Le Pass (1,700m) faces heavy rain advisories or temporary barrier closures, our dispatch team contacts your group leader prior to departure to activate the southern corridor passing near Vinh Hy Bay in Vinh Hai Commune, Khanh Hoa Province and Phan Rang before climbing Ngoan Muc Pass (National Highway 27).

Operational Scenario	Sun Travel Dispatch Action	Route & Fare Policy
Khanh Le Pass is open but afternoon fog is forecast	Move pickup time earlier to 06:00 – 11:30 so the vehicle clears the 1,700m Hon Giao summit in clear daylight	Confirmed base fare remains unchanged; includes fuel, road/BOT tolls, and parking fees
Khanh Le Pass closure announced before departure (heavy rain or night traffic restriction)	Reroute via Nha Trang – Cam Ranh – Phan Rang – Ngoan Muc Pass (NH27) – Da Lat (adds about 65–70 km)	Dispatcher informs you of the added distance and agrees on any fuel adjustment transparently before departure
Traveller wishes to postpone or cancel due to severe weather	Reschedule to the next morning or cancel the booking per traveller request	Rescheduling or cancellation under the Trip terms on the route page; the earlier you tell us, the easier the car is to re-plan

How Dispatchers, Drivers, and Guests Coordinate on Monsoon Travel Days

1. 06:00 Morning Road Status Check: Throughout the October–December rainy season, our operations desk verifies live highway bulletins from road management stations at Khanh Vinh (Khanh Hoa) and Lac Duong (Lam Dong) at 06:00 each morning so you receive updates before checking out of your hotel.
2. Turning a Southern Reroute into a Coastal Sightseeing Drive: When switching to National Highway 27 via Phan Rang, your group can request to follow Provincial Coastal Road 702 past Vinh Hy Bay and Thai An vineyards, as the southern coastal zone around Phan Rang typically enjoys drier skies than the eastern slopes of Khanh Vinh.
