Question: If Moses received the Torah on Mount Sinai by G-d himself why is this Mountain not visited by Jewish people or tourists around the world?
Answer: We would not want people to worship the mountain or to even think that it had more holiness than any other place. The mountain enjoyed a special holiness only for the time that Gd spoke to Moses there. Once that moment passed the mountain reverted to its previous status. We also are not certain of the location of this mountain. The mountain that Christians have identified as Mt. Sinai and have even built a church on has not been verified as the right location.
All the Best,
Rabbi Azriel Schreiber
