Lithuania may lack a Disneyland-style theme park but a multitude of places can be well enjoyed by children and their parents alike.
1.Spend a day at Druskininkai Indoor Water Theme Park, where there are both twisting water slides and a wide array of calm saunas and pools.
2.Vilnius Indoor Water Theme Park is a somewhat smaller alternative to Druskininkai, but a more convenient one if you anchor your trip in the capital of Lithuania (Soviet boroughs). The next-door Ozas hypermarket offers a large non-wet zone of attractions, from to "rock climbing" to foosball.
3.Explore the Vilnius toy museum (in the Old Town) that is especially rich in Soviet toys and copies of Medieval toys. Children may enjoy the toys (playing allowed with some) while adults may either remember their childhood or be interested in learning what toys Lithuanians of their age played in their childhood years.
4.Explore the Museum of Military Vehicles in Vilnius (Antakalnis borough). Many vehicles there may be freely entered.
5.Seek for entertainment at the Basanavičiaus street at Palanga in summer. It hosts numerous seasonal rides, "4D"-to-"9D" cinemas and lotteries while adults may be more interested in live gigs and other events.
6.Cross the Curonian Lagoon to Klaipėda dolphinarium in Smiltynė. Dolphin shows there are aimed at children but may impress a grown-up as well. This is Lithuania where basketball is the second religion, so dolphins show their ability to perform slam dunks. For additional fauna-related family fun, Klaipėda suburbs also host a mini-zoo and a park of dinosaur sculptures.
7.Spectate a match of motoball in Kretinga, which is a kind of football played on motorcycles, practiced only in a few countries. The season is spring-to-autumn.
8.Chill at the HBH park near Palanga. It is large but the rides are "low-scale" without a single theme, such as overbloated replica beetles, a collection of old Soviet cars, a zorbing hill and a paintball field. Adults may also enjoy a multitude of Lithuanian cuisine restaurants.
9.If it is summer you may also visit the nearby family-friendly resort of Šventoji, where there are arguably more rides, rental boats, and other such entertainment. Moreover, the possibility of swinging a narrow pedestrian bridge (so-called "Monkey bridge") while others are walking on it mesmerizes kids.
10.Visit the Museum of Technology in Vilnius. Located in a former power plant (Žirmūnai borough) its old array of turbines has been joined by historic cars and "science games" where children may learn some physics through experimentation.
