3 Things to Do in Cambodia in August
It is best to plan indoor activities in Phnom Penh in August, although it is the city with the least number of rainy days in this month. In Sihanoukville and Koh Kong, the beaches and major attractions are usually not so lively, because the roads leading to them become muddy. Also, the sky will be overcast, making it hard to enjoy the beach atmosphere.
However, Phnom Penh is known as the “Pearl of Asia” because it offers an excellent destination to retreat to. You can appreciate the country’s architecture at the Silver Pagoda and the Royal Palace. In addition, you can shop for handicrafts at the Central Market.
1) Appreciate Another UNESCO World Heritage Site at Angkor Wat
The awe-inspiring temples at Angkor Wat are a must-visit. Appreciate the statues, Buddhist temples, and ancient structures during the off-peak season, when there will not be as many visitors.
Tour guides at the entrance of the site do not charge as much as they do during the peak tourist season.
2) Visit the Silver Pagoda and the Royal Palace in Phnom Penh
Recommended duration of visit: 1–2 hours
Cost: USD 20 per person
