It seems counterintuitive for a growing tour operator to deliberately cap how many people it takes to a destination — but in ecologically fragile places like Deosai Plains or Fairy Meadows, overcrowding is exactly what damages the experience for everyone, including the environment itself.
Group-size caps limit trail erosion, reduce waste at fragile campsites, and keep wildlife encounters undisturbed. They also mean every traveler in the group actually gets a guide's attention rather than being one face in a crowd.
