Yes. To enter the building where religious ordinances are performed it is necessary to be a member of the congregation, but even if you are not yet a member of the Church, you can visit the gardens outside and enjoy the peace of those fields. And if you have questions, you can ask the people who manage the area for explanations of your questions. I think the important thing is to visit the area and feel the peace of that beautiful place.
You can be outside but you need to be a member to enter. There is a desk with information outside as well.
Please note that the Temple is closed Sundays and Mondays.
