An easy city with small children: distances are short, and the attractions that work best sit on the outskirts, each one bus or tram ride from the centre.
Tallinn Zoo
A large zoo in Haabersti at Ehitajate tee 150 / Paldiski mnt 145. The grounds are open 09:00–20:00 with the entrance and ticket office until 18:00; indoor houses close at 18:00 and the children's zoo runs 10:00–18:00. It is spread out — allow half a day.
Energia avastuskeskus
Hands-on science at Põhja pst 29, a short walk from the harbour museums, open daily 10:00–19:00. Adults €16 on weekdays and €18 at weekends, children 3–5 and over-65s €6. Tesla-coil lightning shows at 11:00, 13:00, 15:00 and 17:00 and a 10 m planetarium are included in the ticket.
Tallinn TV Tower
Kloostrimetsa tee 58a, out beyond Pirita, with what the tower calls Northern Europe's highest open viewing platform. From 2 September 2026 it opens Sun–Thu 10:00–19:00 and Fri–Sat 10:00–21:00; an evening ticket from 17:00 is €10, and poor visibility earns a free return visit within two months.
Nõmme Seikluspark
Six high ropes courses plus a separate area for two- to eight-year-olds, at Külmallika 15a in the Nõmme pine woods, with free parking. In September it runs Fri 14:00–18:00 and Sat–Sun 11:00–18:00, weekdays by booking only; trails close by 20:00.
Pirita beach
The city's main sand beach, at the mouth of the Pirita river about 6 km east of the centre on the coastal bus routes. Free, shallow, and genuinely busy only for a few weeks in July and August; the flat coastal path back towards Kadriorg takes a pushchair.
