Problems with duplicates

Hello!

we have a problem with pages duplicates.

Every tour we create has a duplicate with the same SEO metatags.
We scrawled the website and found that.
We want to keep only one version, one landing page by each tour.
Example:

https://pelicanbikerentals.com/product/albufera-park-bike-bike-tour/
https://pelicanbikerentals.com/tours/albufera-park-bike-bike-tour/

How we can delete lading pages with /tours?

Please help us with an advice.
Thank you!
