I took a walking trip with Octo a week ago and came back for a bike tour (day-trip). The trip was about 30km if I'm not wrong. They took you through small lane in Bangkok and cross the river by ferry to the other side of Bangkok. Only a short part was on the road but staff always look after us. I must admit that I've never been to this floating market before although it is so near. Lot of things to see and lot and lot of local foods to try. There is an optional boat ride at floating market (approx. 60 Baht). The ride is about an hour where you can explore life along the klong of this unique city. Enough for Bangkok trip this time and now gotta go back to Phuket.
