I did the trip successfully and it was enjoyable despite the heat ( which peaked at 43 degrees near Kovilpatti ).
Day 0: Started at 7pm from Whitefield. 11pm Salem.
Day 1: Salem - Ettaiyapuram (Bharatiyar house, Ettappa Palace, Kali temple, Muthuswamy Dikshitar memorial ) - Panchalankurichi ( Veerapandia Kattabomman fort ) - Ottapidaram ( VOC house ) - Arumuganeri ( in search of the famous Kattabomman bells ) - Tiruchendur. The stretch between Peikulam to Ambedkar Nagar and thereabouts is so lush green, thanks to the perennial Tamiraparani.
Day 2: Tiruchendur temple - Theri Kadu Dunes - Kanyakumari.
Day 3 : Kanyakumari - Suchindram - Aralvaimozhi windmill road - Nagercoil temple - Padmanabhapuram - Anantya
Day 4 : Anantya - Neyyar - Anantya - Chittar 1 - Chittar 2 dam - Lower Kodhaiyar Dam ( Denied permission ) - Pechiparai dam ( visited the dam and the backwater which is accessible via the CSI church road : you can actually take a dip in the water and there is quite a bit of water - in fact, nearly full ) - Perunchani dam ( had to request many times before they let us in ) - Anantya.
a) At Pechiparai checkpost, they didn't let us go further to Kodhaiyar. They said that entry was allowed only when the Kodhaiyar falls has water. Despite clear boards that vehicles will be allowed at a charge, I was not allowed. Returned without being able to visit.
b) Likewise, near Pechiparai Police station, the gate was closed. I was hoping to drive up to a village called Thottamalai the road for which would go along the backwater, but the gate was closed. They said that we could walk a bit to get some good views or ask someone to open the gate ( the person was not found and I didn't want to invent excuses to venture into a cordoned off area )
c) The good thing is that there are Govt buses to all these places : Pechiparai, Keeriparai, Kothaiyar and at each place I could see the buses either going to the destination or returning.
Day 5 : Anantya - Thirupparappu falls ( absolutely nothing right now ) - Thadikkarankonam - Kalikesam temple / river ( Kalikesam entry closes by 3pm, opens at 9 am ). There was some greenery and the river still gurgled gently along. Was a good experience; then took the Andithoppu road to Aralvaimozhi ( Boy, what a wonderful scenic road ) and then to Tirunelveli (Iruttukadai Halwa and Temple ). Took an auto from the hotel to temple and on the return leg, the kind auto driver showed us important landmarks in the city ( e.g, the double decker bridge from the 70s, Sulochanamudaliar bridge and the story behind it, Vanchai Vilas eatery etc ).
Kalikesam:
Day 6: Tirunelveli - Kayatar (Kattabomman memorial ) - Bangalore. 580 kms in 8.5 hours driving sedately below the speed limit.
I couldn't visit the following due to the paucity of time
a) Kalakad
b) Mundanthurai
c) Manjolai
d) Banatheertham
e) Navakailayam
f) On the Tiruchendur side ( Vanamamalai, Vana Tirupathi, Punnaikayal, Alwar Thirunagari, Sri Vaikundam )
g) Karaiyar
h) Servalar
i) Upper kodhaiyar
j) Kurukkuthurai Murugan temple
Anantya is a fabulous place, glad we booked there!
Thanks all for the inputs. Tinneveli sure has a lot of places.
