If someone has visited Oc Eo under their own steam, can you give me some logistical tips? (here or via els@worldheritagesite.org)
Tour companies from HCM don't seem to be keen to go there, not even for a private tour.
Was thinking of taking the public bus to Can Tho and arranging further transport from there (but it still is 2h away). Or Long Xuyen which is closer but has not so many buses.

Will be there late January.
