How to link taxonomy terms to custom views

How to link taxonomy terms to custom views

I have a vocabulary "destination' with 4 terms (dest1, dest2, dest3,
dest4) Then I have another vocabulary "category" with tons of terms
(parents and childs)
I need to create a custom view (not from core) that will display the
"destination" and also the "category" my content types are associated with
(something like: /dest1/category/child/child, /dest3/category/child).
my setup in short: - I have a view of type "Term", displaying as a block
with one field set as Taxonomy: Term ID set to "Exclude from display" and
another one set as Taxonomy: Term name (linked to its taxonomy term page)
- I have a second view of type "Node" (this is the default drupal taxonomy
term view) with a page display and a Taxonomy: Term ID argument
The setup works (for "category" anyway) until I try adding a destination
to appear in front!! From what I understand I would need to create 3 other
pages with a modify the paths but as soon as I try to change the path
/taxonomy/term/% it defaults back to core display.
any help would be greatly appreciated (hope I gave enough information...
not easy to describe a problem when confused)
Thanks
