In April, I embarked on a week-long journey to Vietnam, focusing on exploring its northern regions. Beginning in Cao Bang province, I then ventured to Ha Giang before concluding my trip in Sapa. This account will concentrate on my experiences in Cao Bang province. One of the highlights of this area is undoubtedly Ban Gioc Waterfall, accompanied by stunning caves and picturesque countryside adorned with majestic mountains, flowing rivers, and lush rice fields. Renting a semi-automatic motorcycle enabled me to efficiently explore all of Cao Bang's attractions in just one day. Additionally, I will provide details regarding budget considerations, transportation options, and accommodation.
