Yes, private tours are quite common for this specific route. About 42% of the options we compare (10 out of 24 listings) are tagged as private tours.

Most tours last between 5 and 7.7 hours, with a median duration of about 5 hours.

Roughly half of the options (12 out of 24) include hotel pickup and drop-off, while another 33% list transportation as included but may specify meeting points instead. It is important to check the specific listing details, as some budget-friendly options may require you to arrange your own transfer to the starting point.
