The Best Places to Visit in Cambodia in September
September is a great month to travel to Cambodia if you are keen to avoid crowds and happy to take a chance with the rain, which often falls in the afternoon and night. Here are some of the recommended places to visit in September.
1. Angkor Wat
No matter when, Angkor Wat is a must-see destination for most guests traveling to Cambodia. The crowds are sparser in September, making it the best time for a relaxed tour. You can expect to see photogenic temples reflected in pools of water, glistening stone structures, and deep green vegetation. Take a moment to breathe in the fresh, rain-washed air in September.
2. Mahendraparvata for the Phnom Kulen Waterfalls
September is a good time to see the waterfalls of Cambodia. Cambodia is home to several breathtaking waterfalls, which are a delight to visit, especially during this rainy time of the year. Do consider venturing out to the Phnom Kulen Falls in the ancient city area of Mahendraparvata. This recently rediscovered city is symbolic to Cambodians, as it is believed that this was where the Khmer Empire began. Other waterfalls you can stop by include Teuk Chhou Waterfalls in Kampot and the famous Boo Sra Waterfall in Mondulkiri Province.
3. Tongle Sap Lake
September is a good time to visit Tonle Sap Lake (biggest lake in Cambodia) as the frequent and fierce rainfall makes the lake bigger and at its most vibrant. Many birdwatchers come to take photos at this time. Take a boat tour to visit the flooded forests and floating villages around Lake Tonle Sap and relax yourself by breathing the clean and fresh air after the downpours.
4. Kratie: Natural Beauty and Wildlife
The tropical province of Kratie turns completely green in September, like the rest of the dense northern jungle of Cambodia. The area encompassing Kratie boasts a 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. Phnom Penh
The capital Phnom Penh should be on your list for a trip in September. There is so much waiting for you to explore in the capital of modern Cambodia and the ancient Khmer kingdom. There you can explore the Royal Palace complex to appreciate the beauty of the architecture and learn more about the history of Cambodia. Spend some time at the Killing Fields of Choeung Ek and Tuol Sleng Museum (notorious prison S-21) to feel the historical terror the nation suffered under Khmer Rouge rule.
Crowding and Costs in September
September is in the low tourist season because of constant rainfall, which makes it challenging to visit different destinations. For this reason, fewer tourists visit Cambodia this month, and most hotels offer good accommodation deals and bargains. All of Cambodia turns lush green, and the lakes expand in size due to the countrywide rise in water levels.
Clothes to Wear in September
Although September falls in the wet season, it is important to note that Cambodia is a hot and tropical country. Synthetic clothes have the benefit of being more quick-drying and breathable, but choose natural fabrics such as silk, cotton, and linen to keep you cool and comfortable when not so active. Loose-fitting light clothes such as long-sleeved shirts and trousers will help protect you from mosquito bites. As it tends to get warm or hot during the day and stay warm in the evenings, jeans would not be a good choice. As there is much rain during September, remember to pack a raincoat or poncho and a light pair of walking boots or shoes, depending on the activities you plan on engaging in.
