This week marks an important holy festival for the Islamic world, Qurban Bayram (Feast of Sacrifice), also known as Eid al-Adha, which will also be celebrated throughout Turkey. As this is the last week before schools start and parents will get time off from work because of the holy festival, children are expected to make the most of it. Theme parks all over the city offer a variety of actives for families to participate together. Whether you want to spend you day with dinosaurs, underwater creatures or roller coasters, Istanbul's theme parks are ready to offer you and your children the most entertaining of times. Jurassic LandLocated at Istanbul Forum Shopping Mall in Bayrampaşa district, Jurassic Land invites people of all ages to discover the world of dinosaurs.

Captain Gaga, the mascot of the theme park, also draws children's attention and helps have a good time. From age seven to 70, people who want to live or re-discover their childhood are invited to experience unlimited entertainment at Vialand.LegolandGrowing up almost everyone played with Legos. Although our sources were limited when we were kids, today's children are much luckier as they can do more than merely play with Legos. For instance, now they can visit a whole park dedicated to Legos, the Legoland Discovery Center. What makes Legoland fun is that children cannot get in without the presence of an adult, and adults are not allowed inside without a child. So, if adults want to have fun, they have to go back to their childhood. The entire entertainment center focuses on creating the environment where parents can spend quality and entertaining time with their children. Considering this fact, Legoland will be a good escape route for families during the Qurban Bayram holiday. Legoland offers various attractions to children: Professor Bric-a-brac takes children on a tour though the Lego Factory and shows them how to make Lego bricks from raw plastic material; the legendary wizard Merlin tests children to see whether they are capable of being his new apprentice; and kids are invited to Olivia's house for a karaoke party.Sea Life IstanbulLocated within Forum Istanbul Shopping Mall in Bayrampaşa, Sea Life is the biggest aquarium in Turkey and one of the best places to spend time with your family. Apart from being a major tourist attraction, the aquarium is also used as a center for marine research and conservation. Children and their parents are able to see over 10,000 sea creatures, including sharks, thornbacks, octopus and sea turtles in an 80-square-meter underwater glass observation tunnel and watch caretakers feed all these animals. Moreover, children are allowed to have their pictures taken with sharks under the supervision of experts and have their birthdays celebrated surrounded by their friends as well as sharks and other sea animals.ForestanbulThe biggest problem about living in a city is that there is not enough open-air space for children to do sports or have fun. Forestanbul aims to provide various activities for children and adults who are yearning to have a breath of fresh air in the middle of the city. Located in Belgrade Forrest in Istanbul's Eyüp district, the park covers 65,000 square meters and offers a variety of activities and adventures for people of all ages. If you want to your children to climb wooden towers – under the watch of professionals of course – or learn archery, Forestanbul is the best choice during the bayram holiday.
