For any first-time visitor to Bangkok, there are certain "must see" sights that you have to visit. While "the Big Mango" is home - literally - to hundreds of museums as well as assorted palaces, temples and other tourist spots, there are three destinations that most will say you need to visit to have "done" Bangkok: The Grand Palace, Wat Po (The Temple of the Reclining Buddha) and Wat Arun (The Temple of Dawn.)
In addition to the 'big three' I've also selected a dozen or so other sights - some popular, some interesting but a bit off the tourist trail - that are easily accessible using the city's train and boat system.
My eGuide, "Bangkok Essentials", combines the detailed information about these sights with useful information about how to get there, as well as how to make your way around Bangkok quickly and easily. The content, most of which is taken from this web site, is enhanced with end-notes giving you background information and bits of trivia you won't find anywhere else. You'll find far more detail than you'll get from any travel guide, in a small format that's easy to take with you.
