Ru Cha mangrove forest stands quietly like a sentinel guarding Tam Giang - Cau Hai lagoon system. Through countless seasons of storms and heavy rains, the ancient Cha trees have remained firmly rooted in the soil, embracing the surrounding villages, blocking waves, trapping sediment, and sustaining the unique ecosystem of the lower reaches of the Perfume River.

On the 10-acre field of red chiem rice (a traditional red rice grown in brackish lowlands of Hue City, sown by April and harvested by July), each planting season requires 40 to 50 hired laborers, and the harvest stretches over several days. Left untended and unfertilized, the rice grows naturally under the generous sun and rain. Some call it “heaven’s rice” — a variety grown from the grace of Tam Giang’s waters.

From May to early September each year is considered the low season for international tourists. However, Vietnam's tourism industry in general and Thua Thien Hue in particular are implementing various strategies to attract foreign tourists, especially from target markets.
