Toloa Rainforest Reserve
LOCATION: The Toloa Rainforest Reserve is located within the grounds of Tupou College in the Eastern District of Tongatapu, near the village of Malapo and close to Fua'amotu International Airport.

OPENING HOURS: Monday to Friday: 8:30am – 3:00pm Saturday & Sunday: Closed
ABOUT: Toloa Rainforest Reserve is one of the last remaining fragments of lowland tropical rainforest in Tonga. Lowland rainforest once covered nearly all of Tongatapu, but today only small patches survive — and Toloa is the largest and most intact of them all.
Spanning approximately 84 hectares within the 750-acre Tupou College campus, the reserve is home to over 200 plant species, many of which are endemic to Tonga and found nowhere else in the kingdom. Towering native trees that Tongans once used for medicine, food, and making dye for tapa cloth still grow here, largely unseen by younger generations of Tongans.
Wildlife is abundant. Keep an eye out for large fruit bats (flying foxes) overhead, the Pacific pigeon, the red shining parrot, butterflies, and lizards throughout the forest. Birdwatchers regularly spot the rare Tongan whistler here.
THE TRAIL: A well-maintained walking trail winds through the reserve, lined with interpretive signage identifying native plant species and explaining their cultural and medicinal significance to Tongan people. The walk takes approximately 10 to 20 minutes to complete and is suitable for all fitness levels. A new Information and Education Centre on site provides additional context for visitors, with photos and displays about the rainforest ecosystem — particularly popular with school groups and families.
CONSERVATION: Tupou College has been the custodian of the reserve since the school relocated to Toloa in 1948. Since 2014, teachers and students have actively worked to remove invasive plant species and mammals, replant native trees, and restore the forest to its natural state. The reserve is officially recognised by the Tongan government and has been nominated as one of Tonga's dedications to the Queen's Commonwealth Canopy initiative. Restoration work continues today in partnership with international environmental organisations including SPREP.
INTERESTING FACTS:
- Toloa was the site of Tonga's first capital, approximately 1,000 years ago
- Tupou College, established in 1866, is the oldest secondary school in the Pacific Islands
- The reserve is strictly protected — all visitors must enter through the college campus
- Over 2,000 invasive plants have been removed from the reserve as part of ongoing restoration efforts
VISITING TIPS: Wear comfortable walking shoes and bring water. Entry is through the Tupou College main gate — introduce yourself at reception before entering the reserve. The trail is short but rich — take your time reading the interpretive signs. Best visited in the morning when wildlife is most active.
