This would be a lovely place to watch the sunrise and reflect off the mountains. If you could get there early enough to grab a front spot.
There was a traffic jam to get up the hill and you need to get out and walk the last bit, with hundreds of others.Unless you are 8 tall, dont expect to see much except other peoples heads! I did manage to get a good spot ( thanks to a very accommodating tour guide) but for the majority of those who also got up at 4am it would have been a disappointment.
There are other places to view the sunrise if you are travelling around West Bengal and Sikkim, so I would have a lie in and save your energy!
