I purchased this map while preparing for a trip to Sikkim. Someone somewhere gave it excellent marks. Plus, I mean c'mon, how many choices do you have for a map for Sikkim?!? We didn't need to navigate ourselves because we hired cars and drivers while there, but I always like a back-up confirmation of where we are and where we're going. This map delivered. It also gave us, during planning, a very realistic view of what we could expect traveling in a mountainous region. It helps figure out how much time (much more than you might think) it will take to get somewhere, etc. For our first trip we made it only around East Sikkim but I'm keeping this map for a hopeful future trip to West Sikkim. Anyone planning to go there, this map will help you.
