If you are looking for a “cool” place to escape the sun in Hanoi, then Ho Quan Son is quite a worthwhile choice.

This area is about 40–50km from the center, notable for its large lake, surrounded by rocky mountains and greenery, making the air much more pleasant than in the city center. Going out by boat in the middle of the lake will clearly feel the coolness and tranquility.

The best time is in the morning or early afternoon, when the sky is bright but not too harsh. Many people choose to go for a day trip, just enough to change the atmosphere without needing too much preparation.

Reference prices:

Entrance fee around 15,000 – 30,000
Boat rental around 100,000 – 150,000

Address: My Duc, Hanoi

If you need a place with both water and trees, and not too far from Hanoi, then this is a very suitable type of location to visit on hot sunny days.
