Ang Kaew Reservoir at Chiang Mai University (CMU), situated at the base of the Doi Suthep mountain range within the Suan Sak campus along Huay Kaew Road, is one of the city's most beloved public green spaces. Built in 1962 as a water catchment reservoir for the university, this tranquil lake features a grassy terraced amphitheater, a paved promenade along the earthen dam ridge, and sweeping panoramas of Doi Suthep. It serves as Chiang Mai's premier community hub for sunsets, picnics, and dog walking. Open daily from 05:00 to 22:00 with free admission.
History & Civil Engineering Heritage
Constructed two years prior to the official opening of Chiang Mai University in 1964, Ang Kaew was engineered to capture mountain runoff from the Huay Kaew stream descending Doi Suthep. Its primary purpose was twofold: serving as the raw water reservoir for the university's water purification plant and preventing monsoon flash flooding on the lower urban plains.
Over the decades, shaded by towering rain trees (Samanea saman) and benefiting from microclimates that keep the air 1–2°C cooler than the city center, the reservoir transitioned into an organic wellness sanctuary where students, local families, and international travelers congregate daily.
4 Essential Activities at Ang Kaew Reservoir
Stroll the Dam Ridge ➔ Lawn Picnic with Mountain Views ➔ Sunset Dog Gathering ➔ Waterside Coffee Break
1. Sunset Picnics on the Sloping Lawn
The eastern shore features a gently sloping Bermuda grass bank. Visitors bring small woven mats to read, relax, and socialize. Facing due west, the grassy bank offers an unhindered panoramic amphitheater view of the sunset sinking behind Doi Suthep.
2. Jogging & Walking Along the Dike Promenade
The flat, paved 500-meter walkway crowning the earthen dam provides an invigorating pedestrian corridor. It links seamlessly with shaded campus avenues, making it a prime early-morning and late-afternoon running course. Looking for more outdoor time around Chiang Mai?

3. The Sunset Pet Social ("Dog Kaew")
Between 16:30 and 18:30, the lawn spontaneously transforms into northern Thailand's most famous informal pet gathering. Golden Retrievers, Corgis, Samoyeds, and Poodles socialise alongside their owners, creating a joyful, heartwarming scene for animal lovers.
4. Lakeside Coffee at Living A Dream by Angkeaw
Perched right at the water's edge, this contemporary glasshouse cafe commands a 180-degree vista over the reservoir. Guests can enjoy single-origin pour-overs, iced matcha lattes, and fresh pastries inside the air-conditioned lounge or out on the wooden lakeside deck.

Local Insider Tips
- The Magic Photography Window: Arrive between 17:00 and 18:15. The sun dips directly behind the mountain ridge, washing the water in soft pastels, amber reflections, and deep twilight silhouettes.
- Vehicular Access & Campus Gates: Campus security gates on Huay Kaew Road and Suthep Road welcome visitors. If driving a rental scooter or car, observe strict parking lines (never park on red-and-white curbstones). If using Grab, set your pin directly to "Ang Kaew Reservoir".
- Pack a Picnic Mat & Bug Spray: The lawn is clean but lacks rental benches. Bring a compact travel mat. After 18:30, lake midges and mosquitoes emerge, so apply organic mosquito repellent before settling in.
