What Is Doi Co Hong?
Doi Co Hong — literally "pink grass hill" — is a cluster of rolling hills about 25 km north of central Da Lat where a native grass species called "co tuyet" (Imperata cylindrica) flushes pink during its seeding phase. The hills sit near Suoi Vang (Golden Stream) Lake in the Ta Nung commune area, at roughly 1,500 meters elevation. For most of the year, the landscape is unremarkable green scrubland. But for a narrow window between late October and early December, the grass heads turn a dusty rose-pink that catches light in a way that looks genuinely surreal against the pine forests and highland sky.
This isn't a curated park or a ticketed attraction. It's open hillside — agricultural and forestry land that happens to do something photogenic once a year. That rawness is part of the appeal. There's no entrance gate, no manicured walkway, and no gift shop. Just grass, wind, and a lot of people with cameras.
Why Travelers Go
Da Lat already draws domestic and international visitors year-round for its cool climate and highland scenery, but Doi Co Hong adds a time-specific reason to visit. The pink grass season has become one of the most photographed natural events in the Central Highlands (중부 고원 / 中部高原 / 中部高原). Vietnamese photographers and social media creators treat it as an annual pilgrimage. For international travelers, it's a genuine oddity — seasonal grasslands that shift color aren't common in Southeast Asia.
The hills also sit in beautiful surroundings. Suoi Vang Lake is right there, the pine forests of the Da Lat plateau stretch out behind you, and the light at this altitude — especially in the golden hour — is distinctly different from coastal Vietnam (베트남 / 越南 / ベトナム).
Best Time to Visit
The pink grass peaks between mid-November and early December. Some years it starts as early as late October; some years it holds into mid-December. The timing depends on rainfall — a heavier wet season can push the bloom later. If you're planning around it, aim for the last two weeks of November for the safest bet.
Morning visits (before 9 AM) get you softer light and thinner crowds. Late afternoon, from around 4 PM, is the other golden window — the grass practically glows when backlit by low sun. Midday is flat and crowded. Weekdays are significantly less packed than weekends, when Saigon day-trippers and local photography groups arrive in force.
Da Lat (달랏 / 大叻 / ダラット)'s dry season runs roughly November through March, so you're catching the tail end of occasional showers. Bring a light rain layer just in case, but most days are clear.
How to Get There
From central Da Lat, Doi Co Hong is about 25 km north, roughly a 40-50 minute motorbike ride depending on which hill cluster you're heading to. The most popular spots are along the road toward Suoi Vang Lake, near the intersection with routes heading toward Da Sar village.
By motorbike: The most practical option. Rentals in Da Lat run 120,000-180,000 VND/day for a semi-auto Honda. The road is paved most of the way, with some dirt tracks for the last stretch to specific hillsides. Manageable for confident riders, but not ideal if you've never ridden in Vietnam — the final sections are uneven.
By taxi or Grab: A one-way trip costs around 250,000-350,000 VND. Getting a return ride can be tricky since you're in a rural area with weak phone signal. Book a round trip with waiting time, or arrange a pickup in advance.
By tour: Several Da Lat operators bundle Doi Co Hong with Suoi Vang Lake and the Langbiang area for a half-day tour, typically 350,000-500,000 VND per person including transport. These are efficient but give you limited time at each stop.

What to Do
Walk the Hills at Golden Hour
The main activity is walking through the grass and watching the light change. The hills are gently rolling, not steep — comfortable for anyone with basic mobility. Pick a hillside away from the main parking clusters and you'll find relative solitude even on busy days. The pink grass is tallest (knee to waist height) on slopes that face east.
Photograph Suoi Vang Lake
Suoi Vang Lake is a 5-minute ride from the main grass hills. The lake itself is photogenic — still water reflecting pine forest — and some of the best pink grass actually fringes its banks. Early morning mist over the lake is worth setting an alarm for.
Visit Da Sar Village
A short ride beyond the grass hills, Da Sar is a K'Ho ethnic minority village with traditional longhouses. It's not a tourism set-piece — people live and farm here. Be respectful, don't wander into private homes uninvited, and buy something from a local stall if you stop.
Hike Toward Langbiang
If you want to extend the day, the Langbiang mountain area is about 12 km further north. The lower trails are an easy walk through pine forest. The full summit hike takes 2-3 hours and gives you a panoramic view of the entire Da Lat plateau.
Just Sit
Seriously. Bring a thermos of vietnamese coffee, find a quiet hillside, and sit for an hour. The Central Highlands have a pace that rewards doing nothing. This isn't a checklist destination.
Where to Eat Nearby
There's no restaurant scene at Doi Co Hong itself — a few mobile vendors sell "banh trang nuong" (grilled rice paper with toppings) and corn on the cob. For a real meal, eat before or after in Da Lat.
Back in town, seek out "lau ga la e" — chicken hotpot with "la e" leaves, a Da Lat highland specialty you won't find in Saigon (사이공 / 西贡 / サイゴン) or Hanoi. Restaurants along Nha Chung street specialize in it, with pots starting around 180,000-250,000 VND. For something quick, the "banh mi" stalls near the Da Lat central market do solid work for 25,000-35,000 VND.
Where to Stay
Stay in central Da Lat and day-trip to the hills. No real accommodation exists at Doi Co Hong itself.
- Budget: Hostels and guesthouses in Da Lat's Ward 1 area run 150,000-300,000 VND/night. Basic but clean.
- Mid-range: Boutique hotels and homestays near Xuan Huong Lake go for 500,000-1,200,000 VND/night. Many have balconies with highland views.
- Splurge: The handful of resort properties on the outskirts (toward Tuyen Lam Lake) charge 2,000,000-4,000,000 VND/night.

Practical Tips Locals Would Tell You
- Wear long pants. The grass is scratchy, and ticks are present in the scrubland. Shorts invite itchy legs.
- Bring your own water. There's minimal vendor infrastructure at the hills themselves.
- Charge your phone before you go. Cell signal is weak to nonexistent in some spots. Download offline maps.
- Don't pick the grass. Seriously. It's tempting. But pulling up handfuls degrades the hillside and it's been a growing problem. Take photos, leave the grass.
- Wear sunscreen. Highland sun at 1,500 meters is deceptive — you'll burn faster than you expect, even on overcast days.
Common Mistakes to Avoid
- Going at midday on a weekend. You'll share every hillside with wedding photographers and tour groups. Early morning weekday is the move.
- Expecting a groomed attraction. There are no bathrooms, no shade structures, and no paved paths. This is countryside. Plan accordingly.
- Visiting outside the season. If you come in March, the hills are just green scrub. The pink window is narrow — check local Da Lat photography groups on Facebook for real-time bloom updates before committing.
- Skipping Suoi Vang Lake. It's right there and adds real variety to the trip. Don't just photograph grass and leave.
Practical Notes
Doi Co Hong has no entrance fee as of 2025, though local authorities have discussed formalizing access — this could change. The area falls within the expanded Lam Dong province. Budget half a day for the round trip from Da Lat including time at the hills and Suoi Vang Lake. Pair it with a Langbiang hike for a full day in the northern highlands.
