One day in Bangkok
Bangkok is a city of contrasts. The city's cultural heritage dates from 1782, when Rama I built his new capital on Rattanakosin Island. In this itinerary, you'll explore this historic island with its famous temples in the morning. When the sun gets at its strongest, it's best to cool down in some air-conditioned malls or indoor attractions. The evening will show you more of Bangkok's modern face, with its bustling and hip nightlife scene.
Note that the Grand Palace, Bangkok's most popular attraction, is purposely not included in this itinerary. As the Palace is located right next to Wat Pho, you can visit it instead or even try to squeeze in both if you wish, but the palace grounds are so large that it's probably best to visit it on a separate day.
According to the World Meteorological Organization, Bangkok is the world's hottest city, so do not underestimate the heat. Start out early if you can, because temple-tramping during the afternoon heat is draining and there won't be much air-conditioning along the way. Drink enough fluids, but don't carry huge bottles of water in your backpack, as there are plenty of convenience stores selling cooled beverages. As you will be walking most of the time, wear comfortable shoes and dress for the climate. Don't go overboard though, pants must have long sleeves and shoes must be neat, as temples and neat restaurants have strict dress codes. There are surprisingly few (good) places to eat in Rattanakosin, so pack in a good breakfast before you go.
There are two parts to this itinerary: a morning of canal cruises and tramping through temples, and two choices for an evening of entertainment, fine food and drinks. As you will be criss-crossing through the city the whole day, get familiar with Bangkok's public transit system. The BTS Skytrain and MRT Metro are the easiest ways to move around Sukhumvit and Silom. Getting to Rattanakosin can best be done over water, with the Chao Phraya Express Boat and the Saen Saep Express Boat. You can also pullover a metered taxi, but you might need to bargain about the fare.
If you keep an eye on your budget, the day won't cost more than B1000, unless you visit Siam Ocean World, which by itself is already a whopping B850. Entry of temples and short taxi rides are not more than B50, while mid-range lunch and dinner are around B250 each. If you are really on a budget, you might want to eat at street restaurants for not more than B50 a meal.
If your accommodation is around Sukhumvit or Silom, your starting point will be Ratchathewi station (N1), easily reached from the Skytrain Sukhumvit line. Take exit 1 and head a few hundred meters south (after walking down the stairs, turn 180 degrees and walk down the street) and walk over the bridge across the Saen Saep canal. To your right, you will see the small, rickety pier called Tha Saphan Hua Chang. Board the next canal boat that comes barreling down towards the west (make sure the boat is heading left as you stand on the pier, from under the bridge) — but move quickly, because these boats don't wait for lingerers! Pay your fare (B10) and enjoy a view into the backyards of Bangkok. Some point of minor interest that you will pass along the way include:
Disembark at the Phan Fa Lila terminus near the Golden Mount. If your accommodation is around Khao San Road, you can just get here on foot. To your left, you'll see a small bridge with oncoming traffic, and a large bridge with multi-lane traffic. Cross the large bridge, pass the white Mahakan Fort and cross the street for Wat Rajanadda, one of Bangkok's unappreciated temples. Entry is free, just take your shoes off and climb into the tower for a bird's-eye view of Rattanakosin.
Once finished, head back to the main street and hail a metered taxi (not a tuk-tuk) for a quick trip to Wat Pho; if you insist on the meter, this won't cost you more than 50 baht. Entry into Wat Pho will set you back another 50 baht. The world's largest Reclining Buddha is in the perennially busy building to your right as you enter. For good luck, you can do as the Thais do and buy a bag of 25-satang coins to plink, plink, plink into the pots behind the Buddha. Explore the rest of the large complex, and if you feel like taking a break, pop into the famous massage school towards the back of the temple grounds. (Building 17 on the maps scattered around the temple).
When done, exit through the west gates (behind the Reclining Buddha) and look for signs pointing towards the pier of Tha Tien, which you will find half-hidden past a market alley full of stalls selling dried squid and such. You will see the white spires of Wat Arun (Temple of Dawn) across the Chao Phraya River. Hop aboard the angular little ferry and pay 3 baht (each way) for the trip. Seeing Wat Arun closer from the gardens around it is free, although quite frankly, it looks better from a distance. You will be charged 50 baht if you want to climb up. Note how the decorations of the spires are in fact all made from millions of bits of smashed white porcelain painted with patterns!
Head back across the river on the ferry you came on and cross the pier to the Chao Phraya River Express dock, clearly identified with blue-and-white signs. Wave down the next southbound (downriver) express boat and ride down all the way to Tha Oriental (N 1) for 13 baht. From there, get to the Oriental Hotel, often judged the best in the world. Just walk down the alley leading from the dock and turn left. Reward yourself with a drink at the famous Bamboo Bar, although (alas!) live jazz is played only in the evenings. It's expensive though: a beer will cost you a whopping 250 baht. You won't get in if you are wearing sandals either.
From the Oriental, head for the Saphan Taksin BTS station (S6) by either taking the express boat one last stop downriver to Tha Saphan Taksin (Central) or by walking out onto Charoen Krung Road, turning left and walking some 15 minutes south.
Take a breather from the sweltering heat at the hotel swimming pool... or, if you still have energy to burn, go shop in any of the air-conditioned shopping meccas on Sukhumvit. Teens will love MBK and women will love the Emporium and Siam Paragon, at least as long as their credit limits allow. Families may like to visit the Siam Ocean World in Siam Paragon, which sets back a whopping 850 baht for adults and 650 baht for children. All attractions can be found at the Siam Square Skytrain station, except Emporium, which is headed at the Phrom Pong Skytrain station.
If you're up for more cultural sights, you might want to visit Jim Thompson's House, which you've seen earlier when boating your way through the canal. The former residence of the American expat Jim Thompson is a kind of ideal-house in Thai-style, and a nice escape from the traffic chaos elsewhere in downtown. Entry is 100 baht and it is easily accessed by the National Stadium Skytrain station. From there, walk 200 meters north into Soi Kasemsan 1.
Two alternative routes here: either the traditional Bangkok of teak houses and go-go bars, or the brash new Bangkok of super hip restaurants and clubs.
Dine at Baan Khanitha, a fair hike down the soi from Skytrain Asoke (E5). Excellent Thai food, although the amount of chili is toned down for tourists (just ask, and they'll spice it up if you're brave enough to try!). Particular favorites here are the pomelo salad (tam som om) and roast duck in red curry (kaeng daeng phed). Mains mostly range around B200.

Hop on the Skytrain and change trains at Siam for Sala Daeng station (S2). Follow the crowds a few hundred meters down Silom Road and through the street market until you spot the signs of Patpong to your right. Pick a go-go bar of your liking, perhaps King's Castle III if you're adventurous and want to see transvestites strutting their stuff. Beers around B70 a pop.
Dine at Bed Supperclub, a fair hike down the soi from Skytrain Nana (E3). A super cool space of pure white where you will lie on futons and dine on a multi-course meal of international fare, complete with a weekly changing floor show. Very expensive by Bangkok standards though, so expect to pay around B1500 per head with drinks. Reservations are obligatory as there is only one setting daily at 9PM. Feel free to stick around for an active nightlife most days of the week (Wednesday is model night).
Take a taxi to State Tower at the western edge of Silom Road, easily spotted thanks to its golden dome, and then ride the elevator to the 63rd floor for The Dome, the world's tallest rooftop bar/restaurant with mind-boggling nighttime views of Bangkok below. Drinks B170 and up, and a live jazz band for free. Take note that there is a dress code: no shorts or sandals.
Touts can be a hassle at many of the better-known tourist sights. Don't trust a single word of unsolicited advice, especially if it involves temples closed for Buddhist holidays, 20-baht tuktuk rides and/or their cousin's jewelry shop. Don't let strangers steer you away from your intended destination.
When taking a taxi, be sure to insist on the meter. If the driver refuses, or quotes silly prices, just walk out and get a different one, as usually there are plenty of them available. If multiple taxis refuse to take you, or you just want to ride it once, you can take a tuktuk. Always agree on a price in advance though.
In the go-go bar zones, beware of touts who try to drag you into the upstairs bars with offers of ping-pong shows and 100-baht beer. The beer may well be 100 baht, but the "show" you'll be treated to will be 1000 baht or more. Rule of thumb is, if you can't see inside from street level, the establishment is best avoided.
