Last weekend we took a morning bike tour on the Mekong islands. We took a ferry, then biked across one island to another ferry then biked across another island and ferried back to the mainland. In total it was about 25km of trail. Some of the trail was road and some was narrow trails in between farms and banana trees.
Along the way we stopped at a silk worm farm and silk weaving place, and a pagoda, but overall the biking was the best part.
