Suggestion for 1 week car trip from Pune in March

Hello, I want to plan something in mid-March with Family for 1 week, basically a road trip in car. The options that I am negating are mysur-cooorg-ooty and Ratnagiri-Konkan belt as I have already done these trips recently. Considering it will be summer need something that is not outright hot. Any suggestions please....Kid want to just do road trip
