Check out their website for the latest volunteering opportunities with TRDC. And incase you’re difficulty figure something out for yourself, just shoot them a general email; Anil Abbi will surely help find something specific for you to do. They however prefer longterm volunteers as it takes time to understand their different projects. Also, their projects are located 4-5 hours outside of Bangalore. So paying a visit itself may take a week or so after one starts volunteering – as visits are planned once/twice a month at best and your visit will be combined with this.
