Hi Summi, there are plenty of trekking options in Mizoram. The only issue is that the trails aren't marked at all. Therefore, it is best to trek with local guides. Besides getting lost, there are no other safety hazards in Mizo hills. The most popular trek in Mizoram is the Phawngpui Peak Trek. The trek takes place within Phawngpui National Park which is home to Tigers, Sambar Deer, Hoolock Gibbon, Barking Deer, Bear and many species of birds.
