State Government tourist departments provide authorised and what is more important in Jeetlandia, vetted tourism service providers for like heritage walk or something, a list of them basically, mind you it will limit your options though, city subreddits are a good resource as well, below are some examples

Also most state governments run their own Tourism Corporation hotels which are strategically located near wildlife sanctuaries, Archeological sites etc., although quality varies state to state and to be frank most in North Indian states are abysmal, best to stick to central government resources wherever available

One archaeological site I'd suggest is the Chausath Yogini Temple in Madhya Pradesh
Some good old world famous sites are the Ajanta and Ellora caves although they no longer allow people inside the caves
