Visited in mid-October after Golden Week — still crowded, but the autumn scenery made it worthwhile. The overnight train was comfortable and well-organised, and our guide managed transfers smoothly between train, bus, and hotel. Jiuzhaigou was stunning — crystal-clear lakes, golden forests, and snow-capped peaks that looked unreal. The park is huge, so having a guide plan the route helped us cover the highlights efficiently. Huanglong was equally beautiful but challenging due to high altitude — bring oxygen canisters and pace yourself. Meals were decent but salty, and the hotel was basic yet clean. Overall, this 3D2N tour offers great value for anyone wanting a fuss-free way to see both Jiuzhaigou and Huanglong. Logistics were seamless, views were unforgettable, and despite the crowds, it’s absolutely worth the trip.
