Filtering data on most recent date

Content

I am creating a report using a custom object linked to a contact. I want to display only the most recent date that is contained in the date column/custom object field for the person. It might make more sense looking at my data:

Contact ID	Park Visited	Date Visited
456789	Hyde	12/05/2014
456789	Smith	10/10/2013
456789	Black	05/05/2015

So all 3 entries belong to the 1 contact, but in my report I only want to see Black Park and the date of 05/05/2015 for Date Visited.

I am not really sure about using functions in expressions etc, so would love some assistance please!

Thanks in advance!
