There is a place called Marutiwadi water sports centre, you can try there Kayaking , flying fox, air rifle shooting, very small cliff jumping barely 6 -7 ft. waterfall rappelling...
You can try white water rafting at Vaitarna River, they may charge around 1000 per person. Another two activities you can do if you like hiking and trekking is Kalsubai Trek and Tringalwadi Trek. Both can take approximately two to three hours depends upon the time you spend. Weekend would be ideal and there are many camping sites which you can try to have a different experience altogether.
You can trek to kalsubai or camping at bhandardhara or sports activities in marutiwadi or fireflies in purushwadi (just before monsoon). you can also explore Vipasna centre there if you want some different experience.
