Most exercises that target your thigh and glutes will definitely help you get rid of cellulite effectively.
One important thing you should pay attention to is working on your overall body fat, especially fat in unwanted areas. So you might want to include some cardio to burn fat.
If bicycling or jogging seems too intimidating for you then you can do some stair climbing A.K.A power stepping or step ups, to get the calories burning.
This can be done with any stairs whether public or private, whichever is convenient for you. The reason why this exercise is recommended is that it’s fairly easy to get started for a beginner and it’s low-nature impact which reduces the risk of injury and strain on joints.
