Kosamphi Forest Park

This section is being updated and will be available shortly.

Kosamphi Forest Park is Maha Sarakham's best-known green space, a riverside woodland in Kosum Phisai district on the banks of the Chi River, famous above all for its large resident troop of long-tailed macaques. Shaded, compact and easy to visit, it is the province's classic family outing.

The monkeys are the draw: hundreds of macaques living semi-wild among tall trees beside the river, a spectacle that delights children and photographers alike. Add the riverside setting, cool shade and the adjacent district town, and you have Maha Sarakham's most accessible slice of nature.

Watching the macaque troop go about its social life, from grooming circles to acrobatics in the canopy, is the headline. The Chi River frontage gives the park its scenery, and the mature trees make it one of the shadier, most pleasant walks in the province.

Stroll the paths under the big trees, observe the monkeys at a sensible distance, and enjoy the river views. The park suits picnics in the calmer corners away from the troop, and Kosum Phisai town next door offers markets and local food to complete the trip.

The macaques themselves are the attraction, best observed mid-morning when the troop is active. The riverside walk along the Chi and the towering old-growth trees that shelter the colony are the park's other signatures.

Quieter stretches of riverbank away from the main monkey zones offer peaceful water views and birdlife. Early morning, before visitors arrive, the park belongs to the animals and the light through the canopy is at its finest.

Local attitudes to the monkeys, tolerated and even cherished as long-standing neighbours, say much about Thai coexistence with animals, echoing temple-monkey traditions elsewhere in the country. Kosum Phisai's markets and riverside temples add everyday Isan culture to the visit.

The park preserves riverside forest along the Chi, Maha Sarakham's major waterway, with tall dipterocarps and fig trees supporting the macaques plus squirrels and abundant birds. Walking is flat and shaded, making this the most comfortable nature outing in the province.

Children love the monkeys, but supervise closely: macaques are wild, bold and quick to snatch food or shiny items. Keep snacks sealed and out of sight, hold small children's hands, and the visit becomes a safe, memorable family highlight.

The park closes with daylight and Kosum Phisai is a quiet district town in the evening. For night markets and livelier dining, return to Maha Sarakham town, an easy drive east.

Portraits of macaques in soft canopy light are the prize; a modest zoom keeps a respectful distance. The river bend, tall buttressed trees and monkeys silhouetted on branches at dusk all work well. Guard your gear; monkeys grab dangling straps.

The forest here survived as riverside common land and was designated a forest park to protect both the woodland and its long-established macaque colony. Kosum Phisai district grew as a Chi River trading stop, and the park has been its recreational heart for generations.

The district lives with the monkeys as a fact of life, and local identity is tied to the river: fishing, ferry memories and riverside temples. Isan language and food dominate, and the park fills with local families on weekends and holidays.

November to February offers cool, dry weather and comfortable walking. Mid-morning is prime monkey-watching time, while weekdays are quieter than weekends. The rainy season keeps the forest lush but paths can be slick.

Expect Isan's cycle: hot from March to May, wet from roughly June to October when the Chi runs high, and cool from November to February. The dense shade moderates heat better than most places in the province.

Kosum Phisai marks the Thai calendar with Songkran in April and Loy Krathong on the river in November, when the Chi comes alive with floating offerings. District fairs and merit-making events occur through the year; check locally for dates.

Arrive mid-morning for the monkeys, walk the riverside paths, then lunch in Kosum Phisai town. Continue to the ancient Buddha images of Kantharawichai district on the way back, or return for sunset at Kaeng Loeng Chan Reservoir near the provincial capital.

One to two hours covers the park and monkeys comfortably; add time for a district-town lunch. It slots easily into a half-day loop west of Maha Sarakham town.

The park sits beside Kosum Phisai town on the route between Maha Sarakham and Khon Kaen, making it one of the easier provincial sights to reach. Buses and songthaews along that corridor pass the district, though a private vehicle remains the most flexible option.

Inside the park, flat shaded paths make walking easy. Kosum Phisai town is adjacent and strollable; for anything beyond, your own transport or passing songthaews on the main road are the means.

Kosum Phisai lies on the Maha Sarakham to Khon Kaen road corridor with regular passing services. Khon Kaen airport is roughly an hour away, closer than Roi Et from this district, and Khon Kaen also hosts the nearest major railway station.

The park is typically open during daylight hours, roughly early morning to evening, in the manner of Thai forest parks. Monkey activity is best mid-morning and late afternoon; check locally for any seasonal changes.

Entry is generally free or nominal, as is usual for forest parks. Vendors near the entrance may sell food; note that feeding the monkeys is discouraged for everyone's safety.

Kosum Phisai town, right next to the park, has noodle shops, som tam stalls and a market with Isan staples. Riverside eateries serving Chi River fish are a district specialty worth seeking out.

Freshwater fish from the Chi, grilled or in spicy soups, headlines the local table alongside standard Isan fare of sticky rice, larb and som tam. Market snacks in Kosum Phisai make an easy movable feast.

Simple guesthouses exist around Kosum Phisai, but most visitors stay in Maha Sarakham town or Khon Kaen city, both within easy reach, and visit the park as a half-day trip.

Costs are minimal: little or no entry fee, cheap district-town food and short transport hops. Even with a chartered vehicle, this ranks among the cheapest wildlife-watching outings in Thailand.

Kosum Phisai's market covers local produce and everyday goods, with occasional OTOP craft items. Serious craft shopping belongs to the province's weaving and pottery villages or town OTOP outlets.

Treat the macaques as wild animals: no feeding, no eye-contact challenges, no visible food or dangling items, and keep bags zipped. Supervise children constantly. If a monkey grabs something, let it go rather than struggle. Paths are safe but watch for droppings.

Flat, shaded terrain makes the park one of the province's more accessible natural sites, though surfaces are earthen rather than paved and facilities are basic. Visitors with limited mobility can enjoy monkey-watching near the entrance areas.

Thai and Isan prevail; English is limited though the park's popularity means gestures suffice for most needs. Sawasdee and khop khun cover courtesies, and a translation app helps with anything more, such as asking where the troop is gathered.

Secure everything before entering: glasses, phones, snacks and water bottles all tempt the macaques. Visit mid-morning, keep a respectful distance from mothers with infants, and combine the park with Kosum Phisai's market for the full district experience.

Bring water in a zipped bag, sun protection, and a camera with a zoom lens. Leave food, loose jewellery and plastic bags in the vehicle; the monkeys associate bags with snacks. Insect repellent is useful in the rainy season.

Do not feed the monkeys; artificial feeding fuels aggression and dependence. Take litter out, keep noise down, and support Kosum Phisai's vendors and eateries so the community benefits from protecting its forest and troop.

Kosum Phisai town and its riverside temples adjoin the park, while the ancient standing Buddhas of Kantharawichai district lie along the road back to Maha Sarakham town. Khon Kaen city, with its museums and lakes, is an hour in the other direction.

The park is managed under Thailand's state forestry and protected-area authorities as a designated forest park. Tourism enquiries for Maha Sarakham are covered by the Tourism Authority of Thailand office responsible for the Khon Kaen area; check locally for current conditions.
