I can definitely recommend a trip with G-Adventures to everyone. Whoever doesn't have the energy or time to prepare their trip and is open to meeting new people is in good hands here. You also have the opportunity to learn about the background stories of the individual countries and support local people or villages. I will definitely do more trips with G-Adentures in my future.

Colors of Bangkok – Half Day Cycling Tour - September 2026

Trip customizable

Best price guaranteed

Colors of Bangkok is a popular half-day cycling tour in Bangkok. Enjoy pedaling through narrow streets and backyards, visit Wat Bang Krasop temple and Sri Nakhon Khuean Khan Park, enjoy delicious Thai meal and explore Bang Krachao “the green lung of Bangkok”. Your tour begins as you cross the Chao Praya River on a ferryboat. While standing on the riverbanks of the Chao Praya River, the many loops running in and out the Bhumibol Bridges I & II at 40 m is sure to impress you. Once you reach the other side of the river, you will find yourself in Bangkrachao sub-district, also called “The Green Lung of Bangkok” or “Bangkok’s green jungle”. It is the biggest & greenest area near the city (about 16 kms). Here, you will cycle on elevated pathways through lush vegetation and under the shade of coconut, palm and banana trees. Our first stop in Bangkrachao is a local, non-touristy Buddhist temple (Wat Bang Krasop). Mind your head when stepping inside the old temple. If time allows, we will pay a short visit to the elementary school next to the temple to say hello to the children. We continue the bicycle ride deeper into the jungle until we reach a Muay Thai boxing gym. Take time to learn about this national sports. Those keen in trying it out can also do so and take a short lesson from the master. Then, we continue our ride crossing a market (if it is open) and visit the beautiful Sri Nakhon Khuean Khan Park, where we take a break and enjoy the scenery. During the ride, we will also make a stop at a local restaurant to offer you a typical Thai meal like “Pad Thai” or “Kao Pad” (fried noodles or fried rice) with shrimps, crab, pork, chicken or vegetarian. Communicate your preference with your guide. After our meal, we return to the pier where we take the ferry back to Bangkok and end the tour. You don't need to be an avid cyclist to join the tour. Colors of Bangkok is an easy paced and relaxed biking trip that is suitable for the young and the old. Note: RBB reserves the right to change advertised itineraries, since schools and local shops may be closed during the weekend, school holidays and national holidays.

What an amazing experience!! We worked with the tour agent for over a year to plan our vacation and it couldn’t have turned out more perfect! Tracey listened to all over our hopes and interests, and delivered an itinerary that ended up being a dream vacation! We spent 2 weeks exploring Vietnam, Cambodia and Thailand with our family of 5 and the guides we had in each city were wonderful, knowledgeable, and felt like our friends just showing us around their country. We will absolutely go through them again when we find time to explore more of Asia!

This trip was a real eye opener into a very different way of life. It was very educational. We enjoyed the perspective of the local people when it came to past issues i.e, the war in Vietnam, the genocide in Cambodia. The group size was wonderful and we got to know each other very well.
