Geology Museum Hanoi
The Geology Museum (Bao Tang Dia Chat) tells the story of the geologic processes that created such breathtaking spots as Halong Ray; however, most of the explanations are in Vietnamese.
It’s located at 6 Pho Pham Ngu Lao (see Central Hanoi map), and is open from 8 am to noon and 1.30 to 4.30pm from Monday to Saturday; but don’t be surprised if it’s closed during ‘opening hours’; entry is free.
