Lumbini is a small town in Nepal where Buddha was born. It is one of the most calm and peaceful places you'll ever visit. The main tourist site there is the Maya Devi Temple, a simple white building marking the exact spot where Buddha was born. Inside the Mayadevi temple you can even see a stone marker believed to be his footprint. Right outside you will find an old pillar put up by Emperor Ashoka over 2,000 years ago, and also a quiet pond where Mayadevi (Mother of Buddha) is said to have bathed. Walking through the gardens, you'll pass dozens of monasteries built by different countries like Myanmar, Thailand, Japan, and Cambodia, each with its own style and colors. You'll very often spot Buddhist monks in their robes walking quietly or sitting in prayer. Also the soft chanting of prayers for some monasteries honestly makes the whole place feel even more sacred.
Drive/Fly from Kathmandu/Pokhara to Bhairahawa, transfer to Lumbini, check into your hotel, and begin exploring the Sacred Garden including the Mayadevi Temple and Ashoka Pillar.
Explore the various international monasteries in the Monastic Zone, visit the World Peace Pagoda, and potentially visit Tilaurakot (ancient Kapilavastu) or Kudan.
Enjoy breakfast, some free time for reflection or last-minute exploration, and transfer to Bhairahawa for your onward journey.
