Hồ Thuỷ Tiên, an abandoned water park near Huế, Vietnam, is a unique urban exploration destination known for its eerie, decaying attractions, particularly the iconic dragon-shaped aquarium. Easily accessible by scooter or taxi from Huế city center (15-20 min ride), it's best explored independently or with a small group, as no official tours exist. While officially closed and without an entrance fee, visitors might encounter unofficial caretakers charging a small fee (approx. 10,000-20,000 VND). The park is open year-round, but the dry season (Feb-Aug) is preferable due to better ground conditions and less risk from crumbling structures, while the rainy season (Sep-Jan) can make it muddy and hazardous. A typical visit lasts 1-2 hours, allowing ample time for photography and exploration. Visitors should exercise caution due to unstable structures, wear sturdy shoes, and note the absence of facilities like restrooms or food stalls.
