Spend most of the day exploring the incredible Angkor temple complex, one of Southeast Asia’s greatest archaeological sites. Visit the many temples inside the royal city of Angkor Thom, including the magnificent Bayon, and other less-visited outlying temples. Particularly impressive are Banteay Kdei and Ta Prohm, the latter still wrapped in jungle roots, just as it was when it was rediscovered almost 140 years ago. For lunch, you can eat in the Angkor temple area, before the tour ends around 3.30pm to 4pm. The rest of the afternoon is free for you to return to the hotel and relax, enjoy the pool, or you can explore the city and market. Alternatively, have lunch in town, then return to the Angkor zone to continue the temples tour, which then ends around 5pm to 5.30pm. Your tour leader will discuss the best option for the day. Accommodation: Baitong Heritage Hotel (or similar)

Visit Angkor Wat, the standout temple in Angkor, for sunrise, witnessing the magnificent structure as the day breaks. Return to the hotel for breakfast, before heading back into the Angkor temple complex for one last exploration. After, you fly to Phnom Penh, ready for your exploration tomorrow. Accommodation: Ohana Hotel (or similar)

Immerse yourself in Phnom Penh today on a full-day tour. This includes the beautiful Royal Palace and the Tuol Sleng Museum (Museum of Genocide), which graphically displays the horrors of the four years when Pol Pot systematically ordered the murder of between 2m and 3m Cambodians. Tuol Sleng was originally a school but was used as a torture and interrogation centre between 1975 and 1979. It is a sobering, depressing and enlightening place to visit. After, we travel out to the ‘Killing Fields’ of Choeung Ek, a mass gravesite discovered after the fall of the Khmer Rouge. Many of the dead were former inmates of the Tuol Sleng prison. Phnom Penh is a city in transition; despite its horrific recent history, it has started to find its feet. Some of its former French colonial buildings have been restored and there is a small but lively restaurant and bar scene developing along the riverfront. The Royal Palace and Silver Pagoda date back to the 19th century and were built in classic Khmer style under the French protectorate. Here, you discover a priceless collection of historical objects giving you an insight into the past achievements of the Khmer Empire. Accommodation: Ohana Hotel (or similar)

Fly from Phnom Penh to Ho Chi Minh City (transfer to Phnom Penh Airport and international flight included). You join the Cycling Vietnam group at the hotel this evening on Day 1 of the main tour. If booking this after Cycling Vietnam, you are transferred (included) to Phnom Penh Airport where your add-on tour ends.
