Skip those 800-baht longtail "tours" that target tourists. Bangkok's regular Chao Phraya River ferry system hits all the same temples and sights for a fraction of the cost – starting at just 15 baht for short hops or 150 baht for an all-day express boat pass.

You get identical views of Wat Arun, the Grand Palace, and Wat Pho, but you're riding with locals commuting to work instead of being trapped with other tourists. Boats run every 10-20 minutes between major piers from 6am to 7pm. The orange flag express boats cost only 20-40 baht and skip some stops, perfect for temple hopping.

Best route: Start at Saphan Taksin BTS station pier, take the ferry to Wat Arun (Tha Tien pier), then continue to the Grand Palace (Tha Chang pier), then Wat Pho (same Tha Tien pier). Total cost under 100 baht vs 800+ for private tours.

Huge advantage: hop off whenever something looks interesting instead of being stuck on a tour schedule. Plus you can grab authentic 40-baht boat noodles from vendors at the piers instead of overpriced tourist traps. Did the math – saved 740 baht using ferries, bought three proper meals with the difference.
