If your Rabbi allows you to go to the Temple Mount or you haven't asked anyone yet and you are thinking of asking a Pro-Temple Mount Rabbi.
Here is a video you might find helpful.
Title of the Video: Rabbi Moshe Dovid Tendler on the Temple Mount
https://www.youtube.com/watch?v=cw91yrKuQec&spfreload=10I suggest you contact Rabbi Chaim Richman of the Temple Institute, "Machon Hamikdash" to ask about the details of the preparations one has to make (such as immersion in a mikva in accordance with halacha) before visiting the Temple Mount.
It is best for someone going the first time to go with someone who has already been there and knows what to do and to inform you which areas are off limits, because there are areas that demand higher levels of purification than just immersion in a mikva, before you can enter them, under normal circumstances.
You should be aware that most (but not all) of the Charedi Rabbis and those that control the Chief Rabbinate are for various reasons against going to the Temple Mount. Some of them are afraid of angering the Arabs. Some claim we might know well enough which areas are permitted to us and which is it a sin to enter. Some claim that for going to the Temple Mount you need a 7 day purification process, with a dip in a Maayan and not just a mikva. Some claim that by religious Jews going up who follow all the rules, this will encourage non-religious Jews who don't follow all the purification rules, etc. to go up to the Mount and they want to claim, we have to take the reactions of the not-so religious into account. Some say the nation has to be on a greater spiritual level as a whole before we can encourage people to go, etc. etc.
Concerning non-Charedi Orthodox Rabbis, I don't believe there is a consensus about the Temple Mount, at least here in Israel, one way or the other.
