The lake is within walking distance of the city center. At the lake you can rent a pedal boat for 40,000 dong for 30 minutes, or 80,000 dong for an hour. Pedal boats are available only on weekends and when the weather is good.
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.
