Don Khon is an island in Si Phan Don.
This is a relatively small island (approx 4 km by 3 km) next to and connected to the even smaller but better known Don Det, but is more upmarket, quieter and with less of the party crowd found on Don Det.
Note that this is not the same island as Don Khong.
From Ban Nakasang you can reach Don Det in 10 minutes by longtail boat, and then walk or tuk tuk to the south end of the island to the bridge (3k nice walk along the west side of the island)
The current “list price” for the transfer is 15,000 kip one way, but most bus tickets include the transfer (save you ticket!)
Crossing the old French railway bridge from Don Det will cost tourists 35,000 kip and 5,000 kip for locals. However this will gain you access to the Li Phi falls for no additional cost.
The toll is not always enforced on the bridge itself, particularly between late afternoon and early morning, but if you want to visit the falls then you may as well pay here as tickets are checked (but are also available) at the falls themselves
