The journey takes me just over an hour and is mostly flat, before leading me up a winding tree-lined hill. On the way up the hill I stop to buy petrol from a small stand and get talking to the owner, a friendly robust woman called Pim.
Pim laughs when she hears that I intend to climb to the top of Erawan Waterfall, the majestic seven-tiered fall that is about 1,500 meters high. "You cannot do it," Pim grins - "you are much too fat!"
I thank Pim for her kind words and continue my journey, noticing how empty the road is and how beautiful the scenery. Before long I have reached the park and leave my bike in the car park.
As I walk through the forest to the first level of the waterfall, I pass by a guide giving instructions to a group of brightly-clad tourists. "Remember, the monkeys like to bite. Last week a monkey bit of someone's hand!" the guide grinned at the look of alarm at the tourist's face. "No, I am joking. But take care."
I pass the group and reach the first level, which is stunningly beautiful. Although only a shallow fall, the water is clear and inviting and the forest backdrop is very pretty. Several people are already at this level, splashing in the water, balancing on logs or eating picnics.
I continue up a flight of steps to the second level, which features a deep pool filled with cool water. It is a long climb up to the third level, and I am hot and breathless by the end of it. I remember Pim's words and wonder if I will make it to the top.
The fall at level three is much larger and extremely pretty. This seems like a good place to swim and its not long before I'm splashing about in the crystal clear aquamarine water. But I am not alone. After a few seconds I am attacked by a school of fish, who are intent on eating my skin. Luckily, these fish are only about an inch long and simply want to feast on my dead skin cells, so I'm safe enough. Still, the fish are persistent ands swimming with them is like being struck by a series of minor electric shocks.
Erawan falls is situated in Erawan National Park, which covers 550 sq kms and receives around 60,000 visitors each year. The falls are named after Erawan, the three-headed elephant of Hindu faith as the falling water is said to resemble the mighty beast.
After sitting sunbathing on some rocks to dry off, I embark on the challenging climb up ton level five. Sweat is pouring off me as I struggle to climb the steep hill. Luckily, there is a lookout point halfway up and I take the opportunity to rest as I enjoy the spectacular view across the lush landscape.My spirits are lifted as I reach level five and am greeted by the sweet sounds of singing, music and laughter. A group of Thai teenagers have somehow carried their guitars up the mountain, and I rest for a while enjoying the way the light blends with the sounds of the birds and the breeze in the trees.
The climb to level six is equally challenging, but once there I am greeted by the sight of a large waterfall and deep pool. This level is completely deserted, and I welcome the opportunity to wade in the waters once more.
After I have rested, it is time to ascend to the seventh and final level. I search in vain for a pathway, finally realising that to reach the top I must climb the steep rock face to the left of the fall. Expecting to stumble at any moment I eventually make it to the top, cross a stream and somehow manage to climb the last 100 metres to the summit.
Hot, sweaty and breathless, I stand and look around. To my surprise I am actually above the level of the jungle and can see for miles in every direction, where varying shades of green mix with bursts of bright colour and the sparkling blue of distant rivers.
Finally, it is time to descend from my lofty perch. On the way back down I am surprised by a group of monkeys, who climb past me down the rocky path without even giving me a second glance. I look jealously at the effortless way they scamper down the mountainside, feeling slow and heavy in comparison.
Finally I am at the bottom and climb aboard my waiting motorbike. On the way back I stop to tell Pim about my adventure. The friendly woman looks at me in surprise. "Maybe you are like an elephant," she tells me. "They look slow but are very powerful." I grin at Pim, realising that this is as close to a compliment as I am ever going to get.
