Khanh Le Pass
Đèo Khánh Lê
Khanh Le Pass (Đèo Khánh Lê) is a pass on National Route 27C in the west of Khanh Hoa province, Vietnam. Vietnamese Wikipedia puts its summit at 1,700 m and notes that a roadside sign at the Khanh Vinh foot of the climb gives the pass as 29 km, while other sources give 33 km[1]. Its summit stands on the boundary between Nam Khanh Vinh commune in Khanh Hoa and Lac Duong commune in Lam Dong province[1].
National Route 27C is 121 km long from Nha Trang to Da Lat[2]. Construction began on 20 April 2004, the first phase opened to traffic on 24 July 2007, and the route was upgraded from provincial roads to a national highway in June 2015[2]. It crosses Bidoup Nui Ba National Park[2].
The pass has a record of landslides. More than 50,000 m3 of earth and rock came down over a 300 m stretch in December 2024[3], and a rockfall in November 2025 killed six people and injured eighteen[4].
Geography and names
Vietnamese Wikipedia puts the summit of the pass at 1,700 m and its position at 12°12′12″N 108°44′06″E[1]. The road over it is signed as 29 km at the Khanh Vinh foot, although 33 km is the figure most sources use[1], and VnExpress also gives 33 km[5].
The pass carries several names: Đèo Omega, from the shape of the road, along with Đèo Hòn Giao, Đèo Bidoup, Đèo Long Lanh and Đèo Khánh Vĩnh[1]. Vietnamese Wikipedia notes that it is not the longest pass road in the country: O Quy Ho on the Lao Cai and Lai Chau boundary runs to nearly 50 km and Pha Din on the Son La and Dien Bien boundary to 32 km[1].
The road to Da Lat
National Route 27C runs 121 km from Nha Trang in Khanh Hoa to Da Lat in Lam Dong[2][5]. Construction started on 20 April 2004 and the first phase opened to traffic on 24 July 2007; the route was designated a national highway in June 2015, having previously been made up of provincial roads[2].
The road crosses Bidoup Nui Ba National Park, which Vietnamese Wikipedia describes as holding some of the most diverse biological resources in Vietnam[2].
The December 2024 landslide
In December 2024 more than 50,000 m3 of earth and rock slid onto the carriageway along a 300 m stretch in Son Thai, closing National Route 27C over the pass for about a week[3].
One lane was reopened at 07:00 on 22 December 2024, and driving over the pass was barred between 17:00 and 07:00 the following morning[3].
The November 2025 rockfall
A rockfall on the pass in November 2025 struck a passenger bus, killing six people and injuring eighteen[4]. Surveys afterwards identified nearly 100 landslide points along the pass, 55 of them large enough to spill earth and rock onto the carriageway[4][5].
From December 2025 the pass was open only between 06:00 and 17:00, and only to vehicles under 5 tonnes and passenger vehicles of 16 seats or fewer[4]. From 13 February 2026 all vehicle types were allowed again, between 05:00 and 18:00, with night traffic still barred because of rain and thick fog[4].
Repairs in 2026
Nine sites on the pass were under repair in 2026, at a total investment of nearly 125 billion VND and a contract value of over 105.5 billion VND[5]. The work ran from 8 June to a deadline of 5 October 2026[5].
On 13 September 2026 the work stood at 40 to 50 percent of volume, and at one reinforcement site 26 of 48 reinforced concrete piles had been finished[5]. On that date the authorities were still advising drivers to avoid the pass between 18:00 and 05:00[5].
