Yes, it is safe to go to Banff now.Between 2022-2023, Banff is actually at an all-time high for tourists and visitors since the return to travel after the pandemic.
Lake Louise itself is 61 km from the Town of Banff. The drive takes about 45 minutes along the TransCanada or an hour if you drive the scenic Bow Valley Parkway.
The town is well-policed and has a low crime rate. Women should still take the usual precautions when traveling, such as avoiding walking alone at night and being aware of their surroundings. Additionally, Banff is a popular tourist destination, so there are plenty of people around to help if needed.
