According to the official Wulingyuan Scenic Area website and other travel reports, it is possible to buy a ticket for the Baofeng Lake drifting tour separately from the overall Wulingyuan Scenic Area ticket.
However, please note that during peak seasons or special events, some attractions within the scenic area might be affected by restrictions or capacity issues. In such cases, purchasing the comprehensive ticket may still provide better access and flexibility in your itinerary.
Before making any final decisions, I recommend checking with the official Wulingyuan Scenic Area website or contacting a local travel agency for the most up-to-date information on tickets and package deals.
