There is no definitive answer to this question as Gangotri is a revered pilgrimage site and therefore any possible drawbacks may be overlooked by some people. However, some possible negative aspects of visiting Gangotri could include the difficulty of the trek to the site, as well as the possibility of crowds and congestion during peak season. Additionally, the high altitude of the area could present some challenges for visitors who are not used to living and travelling at high elevations.
