Last summer, I joined an ecotour in Cúc Phương National Park, Vietnam’s oldest nature reserve. The tour focused on wildlife conservation and sustainable travel. We trekked through dense forests, observed rare langurs, and visited the Endangered Primate Rescue Center. Our guide explained the importance of preserving biodiversity and reducing human impact. We also helped plant native trees to restore damaged areas. Staying in eco-friendly lodges and using reusable materials made me more aware of green living. The experience was very fun, amazing, and wonderful. It taught me how tourism can support conservation and inspired me to be more environmentally responsible in everyday life. I would definitely recommend it to anyone who loves nature.
