MacRitchie Reservoir and Windsor Nature Park - Singapore's Oldest Reservoir with the iconic Tree-Top Walk
Mention MacRitchie Reservoir to any Singaporean, and two things usually come to mind: the dizzying TreeTop Walk suspended high above the forest canopy, and the long-tailed macaques who have ruled these trails for generations. But Singapore's oldest reservoir offers far more than a single bridge and some monkeys — it is a sprawling green sanctuary where history, biodiversity, and recreation intertwine.
Named after municipal engineer James MacRitchie, the reservoir sits within the Central Catchment Nature Reserve — Singapore's largest nature reserve and one of its last remaining patches of lowland rainforest. Together with its smaller neighbour, Windsor Nature Park, this area forms the heart of the island's "green lung," drawing hikers, joggers, birdwatchers, and families seeking an escape from urban life.
History & Heritage
📜 Did You Know?
Prior to colonisation in 1819, much of Singapore would have been covered in lowland rainforest. Today, less than 0.5% of the original primary forest cover remains — and the largest surviving fragments are found right here in the Central Catchment Nature Reserve.
The reservoir's origins date back to 1868, when a generous donation from Straits Chinese merchant Tan Kim Seng enabled the construction of Singapore's first impounding reservoir. It was officially opened in 1878 as the Impounding Reservoir, renamed Thomson Road Reservoir in 1907, and finally MacRitchie Reservoir in 1922 to honour the municipal engineer who oversaw its expansion.
Over the decades, the reservoir was expanded twice to meet the demands of a growing population. Today, it is one of 17 reservoirs in Singapore's comprehensive water catchment system, which covers roughly two-thirds of the island's land area. Rainwater falling in these zones is channelled through a vast network of drains, canals, and rivers into the reservoirs — part of Singapore's famed "Four National Taps" alongside imported water, NEWater, and desalinated seawater.
The Central Catchment Nature Reserve itself was established as a nature reserve in 1990 under the Singapore Botanic Gardens' directorship. It now spans over 2,000 hectares and harbours more than 1,600 native plant species, offering a precious glimpse of the landscape that once covered the entire island.
War Hero's Resting Place
Nestled on a quiet hill within the park lies the tomb of Major-General Lim Bo Seng, a WWII hero who led Force 136's Gustavus V Operation against the Japanese. Captured in 1943, he died in captivity at Batu Gajah Gaol in Perak in 1944, aged just 35. Signboards within the park guide visitors to his memorial — a poignant reminder of Singapore's wartime history amid the tranquillity of nature.
MacRitchie Reservoir Park
The park has been transformed under PUB's Active, Beautiful, Clean (ABC) Waters Programme, which aims to bring communities closer to water. Whether you are after a leisurely stroll or a heart-pumping hike, MacRitchie delivers.
What to Do at the Park
- Reservoir Boardwalks: The Prunus, Chemperai, Jering, and Petai boardwalks hug the water's edge, offering flat, scenic walks perfect for families and photographers. The submerged boardwalk section is particularly atmospheric.
- Kayaking & Water Sports: The Paddle Lodge rents out kayaks and canoes. Shower facilities are available nearby. Note that the reservoir is primarily a water catchment area, so swimming is strictly prohibited.
- Fishing: A designated fishing area exists near the park entrance, but fishing is not permitted within the nature reserve trails. Always check designated zones.
- Outdoor Fitness: An outdoor fitness station sits near the Lornie Trail entrance for those who want to work out with a view.
- Bandstands & Benches: The iconic bandstand — with its distinctive pagoda-style roof — is a favourite photo spot and rest area.
Flora at the Park Entrance
As you enter, rows of vibrant Bauhinia kockiana (with its bright orange flowers) and lipstick palms create a tropical welcome. Purplish bougainvilleas dot the landscape, while rare specimens like the Singapore Kopsia and massive Tiger Orchids reward the observant visitor. When Tiger Orchids bloom, they are truly a sight to behold — though these plants can also be found in other parks across the island.
The TreeTop Walk
The undisputed star of MacRitchie is the TreeTop Walk — Singapore's first free-standing suspension bridge and a genuine bucket-list experience for nature lovers.
🌉 TreeTop Walk Quick Facts
- Length: 250 metres
- Height: ~25 metres above forest floor
- Type: Free-standing suspension bridge
- Connects: Bukit Peirce & Bukit Kalang
- Traffic: One-way only
- Entry: Via Ranger Station (Peirce Track)
⏰ Opening Hours
- Tuesday – Sunday: 9:00am – 5:00pm
- Monday: Closed (except Public Holidays)
- Last entry: 4:30pm from Ranger Station
- Admission: Free
The bridge offers a breathtaking bird's-eye view over the mature secondary forest canopy. On clear days, you can see all the way to Upper Peirce Reservoir. The bridge sways gently underfoot — enough to thrill, but perfectly safe. Because it is narrow and designed for one-direction traffic only, you cannot turn back halfway. Visitors with a fear of heights should proceed with caution.
⚠️ Important
Plan your timing carefully. If you reach the Ranger Station after 4:30pm, the gates to the TreeTop Walk will be closed and you will need to complete your hike without crossing the bridge. During thunderstorms, the bridge may close for safety.
Hiking Trails & Routes
MacRitchie offers six marked trails ranging from easy boardwalk strolls to challenging full-day loops. Here is a breakdown to help you choose:
| Route | Distance | Time | Difficulty |
|---|---|---|---|
| Green Reservoir Boardwalk | 3 km | 1 hour | Easy — flat, shaded, stroller-friendly |
| Purple Lornie Trail Loop | 4.8 km | 2 hours | Easy — wide gravel path, mostly flat |
| Yellow Full Loop (incl. TreeTop) | 11 km | 3–4 hours | Moderate — some slopes and stairs |
| Orange MacRitchie Nature Trail | 7 km | 3–4 hours | Moderate to Difficult |
| Pink Cross-Reserve Route | 9.5 km | 4–5 hours | Difficult — terminates at Rifle Range Road |
| Blue Full Perimeter | 10.3 km | 4–5 hours | Moderate to Difficult |
Route Recommendations
For first-time visitors: The Venus Drive / Windsor Nature Park → TreeTop Walk → return route is the sweet spot. At roughly 5 km round trip (2.5 km each way), it delivers the full rainforest experience and the iconic bridge without committing to the gruelling 11 km loop. Allow 2.5 to 3.5 hours.
For the full experience: The complete 11 km loop circles the entire reservoir, taking you through varied terrain including forest trails, boardwalks, and ridge paths. There are hilly sections and exposed stretches, so bring plenty of water. Water points are available near toilet facilities, but not along the interior trails.
For families & casual walkers: Stick to the Prunus and Chemperai boardwalks along the reservoir edge. These are flat, shaded, and offer excellent water views without the exertion of the forest trails.
Jelutong Tower
Don't miss the Jelutong Tower, a seven-storey observation tower that rises above the tree line. It offers 360-degree views of the forest canopy and is a fantastic spot for birdwatching and photography. Like the TreeTop Walk, it is accessible more quickly via Windsor Nature Park than from the main MacRitchie entrance.
Windsor Nature Park
Hugging MacRitchie on its north-eastern edge, Windsor Nature Park is a 75-hectare gem that offers a gentler, more accessible forest experience. It is particularly popular on weekends, so arrive early if you prefer solitude.
The park's street names — Venus Drive, Jupiter Road, Capricorn Road, Leo Road, and Libra Road — add a charming celestial theme to the neighbourhood. Near the entrance along Venus Drive, rubber trees and coconut palms hint at the area's past as a kampong where villagers worked as rubber tappers.
Trails at Windsor Nature Park
| Trail | Length | Time | Highlights |
|---|---|---|---|
| Hanguana Trail | 350 m | 10 min | Wheelchair-friendly; features endangered native plants Hanguana neglecta and H. rubinea |
| Venus Loop | 1.8 km | 45 min | Part boardwalk, part natural trail; connects to Venus Link |
| Squirrel & Drongo Trails | 2.2 km | 1 hour | Elevated boardwalks up to 4m high; sub-canopy views; freshwater swamp habitat |
| Venus Link | — | — | Connects to MacRitchie Nature Trail and TreeTop Walk (~7 km total, moderate-difficult) |
| SICC Public Access Trail | 1.8 km | 30–45 min | Connects to Upper Peirce Reservoir Park; open 7am–6pm |
The Squirrel Trail runs alongside a stream through freshwater swamp forest, while the Drongo Trail is an elevated boardwalk that lets you experience the forest at sub-canopy level. The steps at the end of Squirrel Trail climb a steep forested slope to connect with Drongo Trail, offering a nice variety of terrain for such a compact park.
💡 Pro Tip
If your goal is the TreeTop Walk, starting from Windsor Nature Park cuts the hiking distance roughly in half compared to starting from the main MacRitchie entrance. It is the preferred route for those who want the highlight without the full 10 km commitment.
Wildlife Spotting
MacRitchie is one of Singapore's best wildlife destinations. While it may not have the wetland crocodiles of Sungei Buloh, its forest ecosystem supports a remarkable diversity of creatures.
🐒 Long-Tailed Macaques
The park's most famous — and infamous — residents. Also known as the crab-eating macaque (Macaca fascicularis), these monkeys are among the most common primates in Southeast Asia. They are frequently spotted near the bandstand, jetty, and Ranger Station.
⚠️ Macaque Safety
- Do not feed them — it alters their natural behaviour and encourages aggression.
- Do not make eye contact or show your teeth (macaques interpret this as aggression).
- Keep bags zipped and do not carry plastic bags or food in your hands.
- Do not use flash photography or attempt selfies at close range.
- If a macaque approaches, stay calm, back away slowly, and do not run.
🦎 Monitor Lizards
Malayan water monitors are common sights, often seen basking on trails or slipping into the water. They may look intimidating but are shy and harmless if given space.
🐍 Snakes
Several snake species inhabit the reserve, including the venomous king cobra and Wagler's pit viper. Sightings are rare, and snakes generally avoid humans. If you encounter one, calmly step back and allow it to pass. Never attempt to touch or handle snakes.
🐾 Other Wildlife
- Sunda Pangolin: Critically endangered and incredibly elusive. A sighting would be the highlight of any visit.
- Colugos (Flying Lemurs): These gliding mammals are sometimes spotted at dusk, moving between trees.
- Squirrels, Skinks & Tree Snakes: Abundant and active throughout the day.
- Birds: Kingfishers, woodpeckers, eagles, owls, sunbirds, and drongos are regularly spotted. The reserve is a haven for birdwatchers.
- Butterflies & Dragonflies: Particularly abundant near the water's edge and along forest clearings.

🚫 Restricted Area: Syonan Jinja
The Shinto Shrine (Syonan Jinja) lies within a restricted part of the Central Catchment Nature Reserve. There are no designated trails to it, and entering closed areas is an offence. Always stay on official paths.
Coast-to-Coast Trail
MacRitchie Reservoir sits at the midpoint of the 36 km Coast-to-Coast Trail, which stretches from Jurong Lake Gardens in the west to Coney Island in the northeast, linking 18 parks along the way. It makes an excellent anchor for a longer hiking adventure across Singapore.
Final Thoughts
Whether you are tracing the boardwalks at dawn, swaying across the TreeTop Walk at canopy level, or spotting a drongo in the sub-canopy at Windsor Nature Park, MacRitchie offers an authenticity that few urban green spaces can match. It is where generations of Singaporeans ran their first cross-country races, where war heroes rest among the trees, and where monitor lizards still rule the forest floor.
So lace up your hiking shoes, fill your water bottle, and step into the green heart of Singapore. Just remember: the macaques are watching — keep your snacks hidden.
