You should say:
I'd like to describe Doi Inthanon National Park in Chiang Mai, which is home to Thailand's highest peak. I first visited it during a university field trip about five years ago, and the experience left a lasting impression on me.
The park is quite unlike the tropical beaches Thailand is famous for. As you ascend the mountain, the landscape transforms dramatically — from dense tropical forest at the base to misty cloud forest near the summit, where the temperature drops to near zero in winter. The summit is often shrouded in fog, and there are beautiful twin pagodas surrounded by manicured gardens that feel almost surreal against the wild backdrop.
What I find most inspiring is the sheer biodiversity — the park is home to hundreds of bird species and an extraordinary variety of orchids and ferns. Standing at the summit on a clear day, you can see an endless canopy of green stretching to the horizon, and the silence is almost absolute except for birdsong.
The experience reminded me that beauty doesn't always require a journey abroad — sometimes it's waiting in your own backyard. Since that trip, I've returned twice and recommended it to every nature-loving friend I have. (≈205 words)
