You can try either of these:

Trust Fall Circles

Form players into circles of between 6 to 10. Players should begin shoulder to shoulder with their hands palms open in front at shoulder height. One player moves to the centre of the circle and is told to close their eyes or is blindfolded. The instructions are that the player in the centre is to allow himself or herself to fall, keeping the feet together and the arms by their side. The players forming the circle must not allow the falling body to breach the circle; they must gently allow the body to circulate among them. Repeat until everyone has had a go in the centre.

Blind Friends

Players pair off. Studying their partner they try to think how they could identify each other if they met blind. They should be encouraged to touch each other�s hair, skin, and the fabric of the each other�s clothes. After a few minutes of exploration the players are told to close their eyes and walk in a random direction being careful how they bump into others. Partners should be well and truly mixed, give the order to try meet up without talking. Once partners have been reunited they should move to the side of the room leaving space until the final two unite. A second step is the players follow the same procedure as above but must find their partners without using their hands.

Blind Discovery Walk

Again, players pair off. This activity takes place outside, preferably in a garden, or enclosed area. One player closes their eyes, and is guided by the other, who must lead the blind partner, taking them to objects that they must try to identify. For this exercise to be effective, the person who is blind should remain so for at least ten or fifteen minutes.

My kids love doing a color hunt, they have to find something for each color, say "This is a (red flower)" or "That is a (white cloud)" and so on and draw a picture of it. There is a worksheet in my printables if you are interested.
