Yen So offers lakeside paths and lawns for an outdoor family break in southern Hanoi. A February 2026 ward report documents a management handover and improvements. Older advertisements for tents, bicycles or barbecues should not be treated as evidence that those services or permissions still apply.

Stroller
Accessible
Age guide A short walking section can suit different ages with close adult supervision near extensive water edges. Do not assume every lawn, play area or path suits strollers or under-threes.
Address and visiting notes
Yen So Lake area, Yen So Ward, Hanoi
The ward's February 2026 report describes a handover and improvement period, not a current service menu. Choose an entrance and turnaround point; consult local notices on closures, parking and permitted activities before bringing picnic equipment.
Around Bay Mau Lake, Thong Nhat Park now has an opened perimeter following the fence removal documented in December 2025. This supports short walks from surrounding streets, but families need a clear meeting point and attention to the transitions between park paths, traffic and the lake.
Cost
Free
Stroller
Accessible
Age guide All ages; good for a short stroller walk, early walking practice and observing trees and the lake with ages 0–3.
Address and visiting notes
Tran Nhan Tong–Le Duan–Dai Co Viet area, Hai Ba Trung Ward, Hanoi
The 21 December 2025 report records full fence removal; a 13 June 2026 report describes an off-lead dog enforcement campaign. Neither guarantees every route is always open or every dog controlled. Set an identifiable meeting point and keep children away from roads and the lake edge.

Nghia Do's January 2026 renovation opening documents paths, a children's playground, toilets and shelters. For families around Nguyen Van Huyen Street, it offers an outdoor visit that can alternate a short play stop with walking. Newly refurbished equipment should not be assumed suitable for every age.
Cost
Free
Stroller
Accessible
Age guide Family paths and a playground are documented, but not every item is confirmed for under-threes. Follow posted guidance and match equipment to the child's abilities, with close supervision near the lake.
Address and visiting notes
Nguyen Van Huyen Street, Nghia Do Ward, Hanoi
The ward records the renovation opening on 29 January 2026. This documents completed works, not a current inspection of each piece of equipment. Follow on-site guidance, avoid maintenance areas and lake edges, and do not treat lighting or cameras as a substitute for adult supervision.
