If using the Pages or Structure modules, just pass in the entry_id of a page to obtain a full path to the page. 

{exp:page_url entry_id='29'}

The base site_url is included by default. To return just the URI to the page, and not a full qualified http:// path, just set include_base to 'n'

{exp:page_url entry_id='29' include_base='n'}
