I participated in mid-June, and it was incredibly hot, so a parasol and sunglasses were absolute must-haves. Our guide, Van, gave very clear explanations! Most importantly, her English was very easy to understand. She mentioned she had learned it herself, and although I was initially worried about understanding, it wasn't too difficult and was very educational. Reviewing the places we visited after returning home will surely deepen my understanding, which is my task now. It was also helpful that we could specify pickup and drop-off locations (within the designated area). The tour includes lunch and two bottles of water, so no worries there! You can enjoy it even if you're traveling alone!
