Love Waterfall (Thác Tình Yêu), which lies within Hoàng Liên National Park (Vườn quốc gia Hoàng Liên; declared an ASEAN Heritage Park). It takes 30 minutes to walk from the entrance of the park to the waterfall. The path is paved with flat but slightly uneven stones and has many steps going up and down. there are many shaded areas for rest along the way. Silver Waterfall (Thác Bạc), regarded by some travellers as less picturesque than Love Waterfall, is alongside the road between Sa Pa and the entrance to Hoàng Liên National Park. You have to take a few hundred steps up to see the waterfall.
Fansipan
At 3,143 m (10,312 ft), Phan Si Păng or Fansipan is the highest mountain in Indochina (Cambodia, Laos and Vietnam), and lies within the Hoàng Liên National Park (Vườn quốc gia Hoàng Liên). Hikes to the summit lasting from 1-3 days can be arranged from tour companies in Sa Pa. Most of them recommend taking the 2- or 3-day options; few guides will take tourists on the round trip in a single day. A very small village offering accommodation and food is around 1,500 m (4,920 ft), and there is an overnight camp at 2,800 m (9,190 ft). Most booked trips will include the use of these facilities in their price should they be required. You should be fairly fit to attempt the ascent.
