You can never forget your first time. For me, it was in Tadoba, the very first time I saw a tiger in the wild. It's a game of sheer chance to see a tiger in its own territory. You can't believe something so majestic and pristine could ever exist. You feel humbled and blessed even overwhelmed by this miracle of nature.
You won't experience the same thrill to see a tiger in captivity. You need to see a king in all his glory on the battle ground, not in a prison cell where he has ceased to be a king.
