Buses leave from Pakse's southern bus terminal and drop you off at the purely ornamental central roundabout. If you are coming on a rented motorcycle you will need to negotiate the ferry crossing. This is not hard. If you are nervous about loading the bike across the gangplank get one of the crew to do it for you. The ferry from Ban Muang on the eastern side of the river costs 10,000 kip. Make sure you bring a hat: There is no shade from the burning sun and the crossing takes 15 minutes. It is real heatstroke territory unless you are careful.
Champasak is eminently walkable. Guesthouses also rent rattling bicycles.
