1. Overview & Significance

Wilpattu National Park is located on the northwest coast of Sri Lanka and stands out for its vast area, ecological diversity, and unique hydrological features. The name “Wilpattu” comes from the Tamil/Sinhala word villu, meaning natural lakes or water basins, which are scattered across the park in large numbers.

Covering approximately **131,693 hectares** (about 1,317 km²), Wilpattu is among the country’s largest national parks. :contentReference[oaicite:1]{index=1}

The park is a mosaic of ecosystems: dry evergreen forest, monsoon scrub, open grasslands, wetland systems associated with the villus, as well as coastal fringe zones. This diversity supports a remarkable array of wildlife and plant communities.

2. Entrance & Access – Eluwankulama Gate

The Eluwankulama entrance is one of the main access points into Wilpattu National Park. It is favored by many safari tour operators due to its proximity to popular villus and high-probability wildlife zones. From here, visitors can embark on game drives that traverse some of the park’s most scenic and wildlife-rich landscapes.

2.1 Getting There

Eluwankulama is accessible via the Puttalam–Anuradhapura road, turning off to a more rugged park road leading into Wilpattu. Many safari providers will pick up guests from nearby towns or accommodations and transport them directly to this gate.

2.2 Permit and Regulations

To enter the park, visitors must obtain a permit. The Department of Wildlife Conservation (DWC) manages entry and regulates the number of vehicles to minimize environmental disturbance.

2.3 Best Time to Enter / Visit

The ideal months to visit Wilpattu are from **February to October**, when the weather is relatively dry, and the villus are more visible. Safari drives are often scheduled early in the morning or late in the afternoon, times when wildlife is more active, and the light is favorable for photography.

3. Historical Background

Wilpattu’s history is as rich and layered as its ecosystem, involving both natural and human narratives.

3.1 Early History & Archaeology

Archaeological evidence scattered throughout Wilpattu indicates that the area was part of an ancient civilization that practiced irrigated agriculture. There are ruins of Buddhist monasteries, stupas, and rock inscriptions, hinting at long-standing human presence.

The Mahāvaṃsa, a chronicle of Sri Lankan history, mentions that Prince Vijaya – credited with founding the Sinhalese lineage – landed near the area now within Wilpattu’s boundaries. There are also references to royalty, such as Prince Saliya (son of King Dutugemunu) who, according to tradition, spent time in this region with his bride Asokamaala.

3.2 Protected Area Status

Wilpattu was first declared a Reserved Forest in 1903 under colonial-era forest ordinances. In 1905, it was designated as a wildlife sanctuary, reflecting growing awareness of its ecological importance. } On **25 February 1938**, it was officially upgraded to a National Park, making it one of Sri Lanka’s earliest national parks.

3.3 Civil Conflict & Reopening

During Sri Lanka’s civil war, large parts of Wilpattu were closed to the public (from December 1988) for safety reasons. The park suffered from neglect and reduced management capacity during this period. Following the end of the war in 2009, the park was gradually reopened, with full public access resuming in the early 2010s.

3.4 Conservation & Modern Challenges

Conservation efforts are ongoing, including infrastructure rehabilitation, anti-poaching measures, and restoration of natural habitats. While eco-tourism offers an opportunity for sustainable engagement, there have been challenges – such as illegal roads fragmenting wildlife corridors. The Sri Lankan Supreme Court has taken action against such developments to preserve the integrity of the park.

4. Geography & Climate

Wilpattu’s geography and climate are vital to understanding its ecological complexity.

4.1 Topography

The park ranges in elevation from near sea level up to approximately 152 meters above sea level. Its terrain includes dry forest, scrubland, open grasslands, and over **60–100 natural villus** (water basins) of various sizes. These shallow saucer-shaped basins fill with rainwater and create seasonal wetlands that are fundamental to the park’s ecology.

4.2 Water Systems

Wilpattu is bounded by two prominent rivers: Modara Gamaru to the north and Kala Oya to the south.Some villus are freshwater, while others are brackish or salt-impacted, especially near the coastal fringe.

There are also ancient irrigation tanks within and around the park, reflecting the region’s long history of water management and agriculture.

4.3 Climate Patterns

Wilpattu falls within Sri Lanka’s **tropical dry zone**, characterized by a mean annual temperature around **27 °C**, though daytime temperatures can rise to 30 °C or slightly more. Average rainfall is roughly **900–1,000 mm per year**, primarily from the northeast monsoon (December–February) and the inter-monsoonal rains (March–April).

During the dry season (May to early September), many of the villus may shrink or dry up, concentrating wildlife around water.

9. Conservation Challenges & Future Outlook

Despite its protected status, Wilpattu faces several ongoing conservation challenges:

9.1 Habitat Fragmentation & Development Pressure

One of the biggest threats is the fragmentation of habitat due to illegal roads or infrastructure development. :contentReference[oaicite:76]{index=76} Such fragmentation can disrupt wildlife movement, especially for large mammals like elephants and leopards.

9.2 Poaching & Human-Wildlife Conflict

Although poaching has declined compared to past decades, illegal hunting and snaring remain potential threats. Human-wildlife conflict, especially in fringe communities, is another ongoing issue.

9.3 Water Resource Management

The villus are central to Wilpattu’s ecology. Changes to water availability — from climate change, altered hydrology, or upstream water use — can severely impact the park’s wildlife.

9.4 Restoration & Monitoring

Management efforts increasingly focus on habitat restoration, reforestation, species monitoring, and community engagement. The DWC and partner organizations are working to strengthen infrastructure, improve patrols, and support sustainable tourism.

9.5 Community Engagement

Local communities around the park rely on forest resources, agriculture, and fishing. Effective conservation includes working with these communities to balance livelihoods with wildlife protection.
