OK, one slight problem with Zone 3.
On the way up we did run into a bit of a traffic jam - I think, even by Indian standards. Normally this road is pretty quiet, but with the first day of the year, and a Hindu temple close to the entrance of Zone 3, it quickly became a mess.
The road was barely wide enough for two cars to pass - and as you can see, there are cars already parked on both sides. Add a couple hundred pedestrians, scooters, and cars trying to go up and down the hill - it was ugly. Perhaps the worst part was when one of those large safari trucks tried to make it up the hill. It was really each man for himself - so those scooters you see there would have a tendency to literally jam themselves into an opening. In one it took us about 10 minutes to back up and make enough space for a car to come down - only to have it filled with scooters. We were lucky - it only took us 45 minutes to go 300 feet to the entrance of Zone 3.
Another woman we met, who was in one of those larger trucks took 2 and a half hours for the same distance - almost too late to even go in the park at all.
