To fill an evening differently from a daytime plan, start with Chiang Mai Night Safari Park. Riding a tram to view animals after dark, it works as an alternative on a night you would rather skip the Tha Phae Gate crowds.
For a hands-on Thai experience, consider the Chiang Mai Muay Thai Gym Thai Boxing Class. It suits an active daytime session before an evening spent at the countdown party.
For teenagers who want more activity, Grand Canyon Water Park is an alternative. Built into a former quarry, it makes for an active day that can wind down into a calmer evening ahead of the countdown.
To fill the evening with a performance, compare Siam Dragon Show Chiang Mai and Miracle Cabaret Show Chiangmai. Both run in an evening slot that wraps up before midnight, leaving time to head on to the Tha Phae Gate countdown afterward.
For an indoor fallback, look at Art in Paradise Chiangmai. Its trick-art indoor exhibition works well for a light one- or two-hour visit.
To take photos near Tha Phae Gate, Sweet Thapae Thai Costume Chaing Mai lets you rent a traditional outfit for pictures around the countdown area. For a short animal visit with children, Tiger Kingdom Chiang Mai is another option. Seats and pickup slots tend to fill earlier than usual over the New Year holiday, so book your preferred date and time ahead.
