Truly appreciate why ‘Our Lady of Paris’ (french for Notre Dame Cathedral) is a gothic beauty from its towers. Sounds cliche but it did felt like I was on top of the world, surrounded by sculptures of saints and monsters, and bird-eye views of the city. Worth the climb!
PS: We used the Paris Pass to get free entry to the towers. Note the ticketing process though to get your preferred reservation. We did not do our homework and had to return later to ascend the towers in the evening even though we arrived at the cathedral early in the morning. Expect a queue!
