If you visit Bali with family and kids, the chance is, your kids might be bored to go just to the temples. Although beaches can be entertaining, it still depends on how far you stay from the nearest beach, and whether that particular beach is safe and fun for the kids. If you are looking for another option to entertain the kids apart from the in-house kids club in your hotel (if available), different playgrounds for kids in Bali can be a good choice, too.
Bali has tons of playgrounds available in each region, such as Sanur, Kuta, Canggu, and Jimbaran or Nusa Dua. Most of them have a single entry price or membership rate for more hours to spend, and some manage to provide playschools if you happen to stay in Bali for a longer time. Note that almost all of them require socks for children and adults to enter and play, which you can bring along your own or purchase them there.
In Sanur, there is a "peek a boo" playground with 1,000 sqm (10,764 sq. ft.) indoor and semi-outdoor playing area for baby, toddler, and children under 10 years old. A good thing about this playground in Bali is that adults can order food and chill at their air-conditioned cafe area while waiting for the kids playing. They also provide regular classes every month, such as gymnastics, aikido, capoeira, etc.
Further down the south-west of Bali, Canggu has friendly playgrounds with an indoor and outdoor playing area. Some are the Cubby House Kids Club (they have cooking school every Saturday), or Parklife Bali (a multipurpose venue for family, including a park, playground, playschool, and restaurant. Free activities are included with the park entry). Some other places and restaurants in Berawa also have enjoyable playgrounds to play, such as the Tamora Gallery (perfect place to eat, shop, and play), and The Joglo Café restaurant in Berawa. This region is developing so they might have more in the future.
Kuta is located in the south of Bali. Although Kuta is packed with vibrant life for adults, it also has something for the kids. For example, Beachwalk Mall Kuta has a Minneapolis playground on the third floor (malls are always favorable for the whole family). Sunset Road has a Hide N Seek (they have a restaurant and café as well), and Legian has an underwater-themed indoor Waka Waka Bali Playground (located inside the hotel by the beach, but its playground is open for public). Each hotel in this area might also have an excellent playground in Bali for kids to play.
Jimbaran and Nusa Dua
In Jimbaran and Nusa Dua, although you stay in the area surrounded by many top-rated resorts, which might have an in-house kids club, it is always good to have some options outside to keep away the boredom of the kids. In Jimbaran, we have a Jungle Play Bali with a treehouse, playhouse, mini farm, and some add-on activities with additional charges. Meanwhile, in Nusa Dua, Pirates Bay can also be the place to chill by the beach while your kids playing outdoors; well, who doesn't love everything about pirates anyway?
