As much as you'll want to laze around on the beautiful beaches of Cambodia during your honeymoon, what you should actually be doing is, trying out the delicious local food and sharing smiles with the locals. Visit the S.E. Mountains, the largest mangrove forest in Asia, take up an adventurous trek, head to the last natural Island, Rabbit Island of Kep, or sign up for a motorcycle tour to explore the remote and unexplored parts of the country with your special one.
