For stay, I would suggest Homestays near Jog Falls (Reseve Camp area). If u arrive in the morning, get down at Sagara and take bus to Sigandur. Return to Sagara by noon. Then take bus to Jog Falls. Check in homestay and visit Jog Falls in the evening. Next day, check-out and continue your journey towards next destination. Nearby, u can visit Honnemaradu, Sharavathi Nature camp, etc.
