New York (CNN Business) Airbnb is adding trip packages as it evolves into a full-fledged travel company.

The home-sharing company on Thursday launched Airbnb Adventures , which it describes as a collection of "bucket list worthy multi-day experiences" in places around the world. The packages vary widely in price, depending on the length and location of the tour.

Airbnb is entering a crowded space dominated by other companies, including Contiki and G Adventures. But Airbnb, which is worth about $31 billion, is transitioning its business model from exclusively renting homes and apartments into building a platform that helps people with all aspects of travel, including where to stay, what to do and how to get there.

Adding Adventures helps Airbnb diversify as it gears up to go public. Airbnb cofounder and CEO Brian Chesky has previously said that the company could potentially go public "later this year."
