Believed to contain the most biodiverse marine habitat on the planet, the waters surrounding Raja Ampat are home to 600 species of hard coral and 1,500 types of fish – more than anywhere else in the world – which makes for exceptional diving and snorkelling experience.

3rd03 | NovNov | 202626 | Semarang, Indonesia | ||||
Semarang is one of the oldest cities in Indonesia, situated on Java's north coast between the shore of the Java Sea and a small ridge of mountains. Ceded to the Dutch West India Company in 1677 by King Amangkurat I in payment of his debts, it became their headquarters and the seat of the Dutch governor of the northeast provinces. Semarang's usefulness as a port waned due to the gradual silting up of the harbor; by the 19th century, Surabaya had eclipsed Semarang as Java's premier port. With a population of over one million, a third of whom are thought to be of Chinese extraction, Semarang is the largest city in Central Java and its administrative capital. The city consists of two parts: the coastal lowland where most of the commercial activities are found; and the hilly residential area. Although more a business center than a city for tourists, Semarang serves as a popular gateway to the mountainous interior of Central Java and to fabled Borobudur. Semarang, a bustling port city, offers a captivating blend of Javanese, Chinese, and Dutch influences. Its colonial architecture, vibrant markets, and delectable cuisine make it a fascinating destination. However, the allure of Central Java extends beyond the city limits. Borobudur, a world-renowned Buddhist temple and a UNESCO World Heritage Site, is an awe-inspiring monument, and a testament to the architectural brilliance of the Sailendra Dynasty. Its intricate carvings and serene atmosphere offer a spiritual and historical experience like no other. The journey from Semarang to Borobudur is a picturesque adventure. As you venture into the heart of Central Java, you'll be greeted by rolling hills, emerald rice paddies, and charming villages. This idyllic countryside provides a tranquil escape from the city's hustle and bustle. Approaching Borobudur, the landscape transforms into a lush, tropical paradise. The majestic temple emerges from the greenery, a breathtaking sight that will leave you in awe. Spend the afternoon exploring the temple's grounds, enjoying its serene atmosphere, and gaining insights into its rich history. | |||||||
4th04 | NovNov | 202626 | Kumai, Indonesia | ||||
Kumai is a port town in southern Borneo and serves as the gateway to Tanjung Puting, one of the most important national parks of Indonesia. This largely undeveloped and wild national park possesses the largest and most diverse examples of coastal tropical heath and peat swamp forest of southern Borneo. Declared a National Park in 1982, orangutan and other primate species can be found in the park. Using Zodiacs and local boats to cruise into the Tanjung Puting National Park one of the main goals is to take a private tour of Camp Leakey, the landmark research station. Meeting Dr. Biruté Mary Galdikas, one of the founding scientists, and learning of her 45 years devoted to the study, care and preservation of endangered orangutans will be a highlight of the Camp Leakey visit. In the late afternoon we arrive at the heart of Central Kalimantan, Kumai. As your expedition vessel arrives, you'll be greeted by the lush tapestry of Borneo's rainforest. This evening, experience the magic of the night as you glide through the tranquil waters of the Sekonyer River. This enchanting nocturnal adventure offers a glimpse into the hidden world of the Borneo rainforest. Keep a watchful eye for elusive creatures as you navigate the river. The rhythmic symphony of the jungle, punctuated by the twinkling lights of fireflies among the nipa palms, creates an unforgettable ambiance. | |||||||

Embark on an unforgettable adventure through the lush rainforests of Tanjung Puting National Park. This iconic reserve is home to a diverse array of wildlife, most notably the endangered orangutan. Cruise along the meandering Sekonyer River aboard a traditional Klotok houseboat, immersing yourself in the heart of Borneo's wilderness. Encounter proboscis monkeys, gibbons, and a kaleidoscope of birdlife as you navigate through the dense vegetation. Visit the renowned Pondok Tanggui Rehabilitation Centre, where you'll have the extraordinary opportunity to witness orangutans in their natural habitat. Learn about the park's vital conservation efforts and the dedicated work to protect these magnificent creatures. Continue your journey to Pesalat Conservation Education Centre to deepen your understanding of the challenges faced by the park. Conclude your time in Kumai with a morning visit to Tanjung Harapan, where you can observe orangutans during their feeding. This awe-inspiring experience will leave you with a profound appreciation for the delicate balance of nature and the importance of conservation.

8th08 | NovNov | 202626 | Singapore, Singapore, disembark the Greg Mortimer | ||||
The main island of Singapore is shaped like a flattened diamond, 42 km (26 miles) east to west and 23 km (14 miles) north to south. Near the northern peak is the causeway leading to West Malaysia—Kuala Lumpur is less than four hours away by car. It is at the southern foot where you will find most of the city-state’s action, with its gleaming office towers, working docks, and futuristic "supertrees," which are solar-powered and serve as vertical gardens. Offshore are Sentosa and over 60 smaller islands, most uninhabited, that serve as bases for oil refining or as playgrounds and beach escapes from the city. To the east is Changi International Airport, connected to the city by metro, bus, and a tree-lined parkway. Of the island's total land area, more than half is built up, with the balance made up of parkland, farmland, plantations, swamp areas, and rain forest. Well-paved roads connect all parts of the island, and Singapore city has an excellent, and constantly expanding, public transportation system. The heart of Singapore's history and its modern wealth are in and around the Central Business District. The area includes the skyscrapers in the Central Business District, the 19th-century Raffles Hotel, the convention centers of Marina Square, on up to the top of Ft. Canning. Although most of old Singapore has been knocked down to make way for the modern city, most colonial landmarks have been preserved in the CBD, including early-19th-century buildings designed by the Irish architect George Coleman. Disembark in the early morning and bid a fond farewell to fellow travellers before a transfer to the airport to continue your journey. |
