Hay-on-Wye. Also known as "the town of books", this little village in Wales is quite possibly the most charming and simultaneously intellectually stimulating community in the world. Renowned for their many bookstores and annual literature festival (which Bill Clinton once called "the Woodstock of the Mind"), Hay is a bookworm's dream come true.
The Houston Zoo is a must-see if you are visiting the city! The zoo grounds are very well maintained and the landscape is beautifully designed. If you love spending the days outdoors, this is a great place to just wander. Check out Hermann Park too, which is walking distance from the zoo.
