I was inspired (most) at the following locations:
Kosel (Western Wall) – Jerusalem
Kever Rochel – Bethlehem
Me’orat Hamachpeila – Hebron
Kever Yosef (Hatzadik) – Nablus (Shechem)
Rebbi Shimon bar Yochai – Meron
The following are famous as well:
Har Hazeisim (Jerusalem) – Zecharya Hanavi, Bartenura, Ohr Hachaim and more
Tzfas Cemetery (Safed) – Rabbi Pinchas ben Yair, Rabbeinu Bchayei, Arizal, Beis Yosef and more
Teverya (Tiberias) – Rebbi Meir Baal Haneis
There are many other places in Teverya (Imaos, Reb Chiya, Talmidei Rav, Cemetery etc.)
On the road between Tzfas and Miron you can make many stops (Rebbi Yehuda bar Iloi, Krispidoi etc.)
There are more Kevarim in many small towns in the Galilee.
