We had visited pelling in off-season (june ending).
Overall it is a very nice place for those who love natural beauty and adventure. It has scenic lakes, awesome waterfalls, rapids, gorge bridge, rock garden and monasteries. Yes lots of waterfalls , monasteries. You also get to see scenic views of everest, K2 , himalayan peaks.It's thin roads are prone landslides frequently.
Only problem we suffered was for food. We had to order 2 hours in advance, no restauran had ready food available. On top of that very few choices left for veggies in cuisine.
If food is not the priority then it is a must visit .......... as it is a very different and un-touched hill station.
