Kenny, on the other hand, likes the view that he gets from the top of the mountain, and he enjoys hiking in the forest. what sentence type is it?

The answer is: compound sentence.

Compound sentences contain two or more independent clauses. They can be joined with a comma and a coordinating conjunction, or a semicolon plus a comma after the coordinating conjunction.

In the example sentence, the clauses separated by a comma and a coordinating conjunction are independent because they are both complete thoughts on their own: "Kenny, on the other hand, likes the view that he gets from the top of the mountain," and "he enjoys hiking in the forest."
