What are some harbors?

The harbors were the entry points of many immigrants coming from Europe. Some came with very little money, and settled in the cities by necessity, hoping to get factory or labor jobs. In addition, many of the necessities needed by the colonists came from Europe and the Caribbean and arrived at the harbors, which made these locations desirable for merchants.
Cities on the eastern seaboard of the United States that have harbors include Baltimore, Charleston, Boston, and Providence. Cities with harbors on the Gulf Coast include Galveston, Key West, Mobile, and New Orleans. Towns with harbors on the west coast include Anchorage, Los Angeles, and San Francisco.

Your grammar is a bit...ambiguous, but perhaps you mean "did Europe's navigable rivers and good natural harbors make trade difficult? If this is the case, then the answer is no. Rivers and harbors HELPED European trade. Goods could be moved up rivers or into natural harbors for docking, making trade easier.
I am going to try and improve this answer slightly. I think with the word "port" there is a little more guarantee that there is "port authority" involved and more police patrol, protection, guarantees for security for import and export trade business etc. A harbor doesn't necessarily define that. However many ports are called Harbors because they originally were harbors without port authority. All ports are harbors. All harbors are not ports.
