If you're living in Hanoi and too busy to get few days trip, Palm Hill Villas is definitely the right place for you. The resort is about 40kms north west of Hanoi. It'll take 30 minutes to travel by car.
My family rented a villa in 2 days. The price is about 3.5 - 4 million VND ($150-200) for a 2 floors villa per night included breakfast. Sounds seem expensive but the villa can accommodate 10 adults. We planned to participate in some outdoor activities such as: swimming, playing soccer, riding bicycle. My mom was preparing some raw ingredients at home so we can hire a charcoal grill to make a BBQ party.
If you are looking for an entertainment center or a cinema. There's nothing like that here. It just only you and nature. I love the moment when I could sitting alone and thinking about life. Maybe I would not think anything at all. I still wanted to sit there, closed my eyes and took a deep breath. I thought it was a special smell of the forest after rain.
How long since the last time you've heard a bird tweeting in the morning? Take that chance now!
