The best walks and cycle rides are the ones where you can escape the hustle and bustle of the city. One way of doing this in Samut Prakan is to do the Gulf of Thailand route which is 11.6 kms one way. You can either return the same way or come back along Sukhumwit Road. I first did this route back in 2009 (see blog here). At that time it was only suitable for walking. However, they have now paved much of this coastal route. Though, please be aware, with storms hitting the coastline, there is no guarantee that the path will still be in a good condition.
One of my favourite destinations in Samut Prakan is Ban Khun Samut Chin. This is an isolated community along the coast that has moved numerous times due to land erosion. The only people that refused to move were the monks at Wat Khun Samut Chin. The temple is now surrounded by the sea and is only accessible by an elevated walkway. I first visited this community about nine years ago in 2007. It’s not easy to reach there as there are no roads. You have to rent a boat and then walk about two kilometers. But, the effort is certainly worth it. Although I have now been many times, I had never been all the way by bicycle before. This was the challenge when I set off there recently with two cycling friends. It wasn’t an easy route, and certainly you need to be fit and able. Plus you must take plenty of water and food too. But, it was well worth the effort.
