Tell me whether 'Sri Nimishambha Temple, Ganjam' refers to Ganjam district in Odisha (far from Tamil Nadu/Karnataka) or a different local Nimishambha temple; also give your start city, number of days, and travel mode so I can plan logistically.
Please state travel dates, preferred daily pace (relaxed/moderate/fast), accommodation budget, and any mobility limits so I can tailor walking and hill visits (Chammundi Hills, Tiruvannamalai) accordingly.
