Permissibility of a female visiting Darghas,mazaars

Slm’s respected Mufti, i would like to ask for maaf first in taking time out of your hectic schedule. i have one question & hopefully Mufti will be able to help me. i know it is not permissible for a woman to visit any grave but what about the graves of saint’s & the mazaars & darga’s of these pious people that i witnessed so many women go to. is that permissible? if yes can a woman recite the quraan or yaseen inside one of the mazaars visited…please help me maaf if this is a stupid question to ask but i need clarity.
jazakallah,
slms & dua’s.
