BTS Saphan Takin is on the Silom line in Sathorn district in Old Town Bangkok. The great thing about it is it's connected to many nearby piers and tourist attractions. From the pier, you can easily go to Asiatique, Icon Siam, Long 1919, Chee Chin Kor temple, or simply take a cruise on the Chao Phraya River and stop at the flower market, the Grand Palace or Wat Arun. From the bridge itself, you have the views on the river and the Ferris Wheel of Asiatique further away, which is pretty scenic with all the boat sailing up and down the river, a great place to do some timelapses. Another view would be under the bridge where some long exposures are nice with Shangri La hotel in background. Another famous building nearby is the ghost tower, but at the time of writing, it's still forbidden to go inside, even by paying the security guard. Instead you could book a room in thee Lebua Tower where you can get beautiful views from your balcony and enjoy one of the best rooftop of Bangkok (very pricey though). Lastly, you can shoot what we call the trident of Bangkok, either from Villa Sathorn condominium rooftop (if you're invited) or by drone from the small park at the branch.
