My friend and I really really enjoyed our 4 day, 3 night cycle tour of the Mekong Delta with Sinhbalo and would recommend it unreservedly to anyone wanting to see this part of the world by bike.
First, our guide, Loc. He did a great job. He was always on time, gave us great information at each place we visited, took us to really good restaurants and ordered a wonderful range of dishes that we hadn't tried before. He was super helpful with my friend who had raging tonsillitis for the whole trip. He did everything he could to make the trip comfortable and meet both our needs, given that my friend needed to rest while I felt fine and could do the usual itinerary.
On that note, I also want to acknowledge how great the company was regarding last minute changes to our group (a third friend was supposed to join us but had also been taken down by some super flu bug) and changing our accommodation to a hotel instead of a homestay so we could be closer to a hospital on the last night.
The tour lived up to the description given to us regarding getting off the beaten path. I think we saw other tourists cycling only once in four days and that was only when we had to use a larger road to get to the next smaller path. The routes we took had a different feel each time and we felt like we got to see a nice range of places in the delta. Cycling on little paths between the houses and having the local children call out hello to us as we went past was my favorite part.
The tour included a nice mix of cycling, activities such as boat tours of a mangrove forest, fish farms and a floating market, and downtime to relax. Pretty much everything is included in the price apart from a few drinks. It was really enjoyable to not think about organising anything or paying for anything for those days.
All in all, I highly recommend both our guide, Loc, and the company as a whole. You won't regret taking one of their tours.
