The Best Places to Visit in Cambodia in October

If you don't mind the hot and humid weather conditions too much, October may interest you as the last month of the year when you don't have to join large crowds of visitors in the major tourist attractions. Here are some of the best places to visit in October.

1. Angkor Wat

Visit the Angkor Wat temples for a tour of one of the world's top heritage sites. Local tour guides can tell you the legends of the mysterious ruins, take you to awesome places for a photo session, and show you the best spots for viewing the sunset. You should be careful when visiting the Angkor Wat temples in October, because there might be sudden downpours. Come prepared with a raincoat, just in case it starts raining during your outing.

2. Phnom Penh

As the capital of Cambodia, Phnom Penh is rich in ancient temples and museums, where you can enjoy shelter and history for long periods, even on rainy days. Spend a day to explore the Royal Palace complex and National Museum to appreciate the beauty of the architecture and learn more about the history of Cambodia. It is worth spending some time at the Killing Fields of Choeung Ek and Tuol Sleng Museum (the notorious S-21 prison) to learn more about the historical terror Cambodia suffered under Khmer Rouge rule. There are numerous fun things to do and see too in the capital city.

3. Kampot

October is suitable for exploring Kampot's richness of waterfalls, mountains, and caves. Located in the south of Cambodia, Kampot is well-known for its beautiful scenic landscape and old colonial buildings. There you can explore the French hill station of Bokor National Park to learn more about its colonial history. Explore the ancient ruins at the Kampot Kampong Trach caves, or wander around the town's French-colonial and Chinese-style shop houses. You can also take a small boat on the Kampot river to cruise through the small town.

4. Kratie: Natural Beauty and Wildlife

October is a good time to explore Kratie, as the tropical province is as completely green in October as the rest of the dense northern jungle of Cambodia gets. The area encompassing Kratie boasts a big variety of flora and fauna, especially in the huge nature reserves, where monkeys, different species of reptiles, and rare river dolphins can be spotted. Spend some time to visit the Mekong Turtle Conservation Center and Phnom Sambok Pagoda if you have more time.

5. Battambang

October is the best time to view the beautiful landscape of Cambodia as the downpours wash everything clean and green. There are numerous activities you can do in Battambang, including crocodile watching, birdwatching, biking around the villages, kayaking along the river, visiting the countryside, or taking a bamboo train to explore around the city.

Crowding and Costs in October

October is the last month of the wet season, when Cambodia receives only a few visitors before it enters the peak season. Many 3-star and 4-star hotels offer fantastic deals during this month. Only a few of the most popular outdoor activities are open in the major tourist cities of Cambodia. You do not need to book a hotel in advance because, during this time of the year, Cambodia has very few visitors.

Clothes to Wear in October

During the daytime, when the weather is hot and humid, wear light clothes, t-shirts, shorts, and other summer clothing. It is recommended to pack some warm clothing, such as a jacket or jeans to avoid feeling cool on some evenings and early mornings, especially in mountain areas like Kratie. Rain mostly falls in the afternoon or late at night. A raincoat or umbrella is generally advisable to take if you are going out during this month, though.
