For a first Bangkok temple day, focus on old Bangkok: Grand Palace, Wat Pho, Wat Arun, and one smaller stop if you still have energy.
Do not turn temple visits into a checklist. Heat, dress rules, crowds, and transport make a focused route better than trying to see every famous name in one day.
Dress and behaviour
Dress modestly for temple visits. Shoulders and knees should be covered, and shoes usually come off before entering important halls.
Keep your voice low, avoid blocking worshippers, and do not treat Buddha images as photo props. If a rule is posted at the entrance, follow the local sign rather than an old blog post.
Old-town route
The classic route is Grand Palace and Wat Phra Kaew, Wat Pho, and Wat Arun across the river. This works because the sights are close enough to make a logical route.
Start early if you can. The old city gets hot, and the biggest sights can feel crowded later in the day.
Wat Pho
Wat Pho is one of the most rewarding temple stops because it combines the Reclining Buddha, courtyards, chedis, massage history, and a location close to the river.
It is a useful anchor for a first temple route because it sits between the Grand Palace area and the river crossing to Wat Arun.
Wat Arun
Wat Arun is best treated as a river stop. The temple is visually strongest from across the water, but visiting the grounds adds texture to the route.
Use the river rather than forcing every movement by road.
Other temple stops
Wat Saket gives a different old-town view from the Golden Mount. Wat Traimit pairs naturally with Chinatown and Yaowarat Road. Erawan Shrine is not a temple in the same route sense, but it is a central religious landmark near Ratchaprasong.
My Bangkok advice
Plan temples around heat and respect, not only photos. Wear the right clothes from the start, carry water, move by river where possible, and leave space in the day for a slow meal or shaded break.
