The Muak Lek Arboretum is open to visitors every day from 08:00 AM to 04:30 PM, with no weekly holidays, allowing travelers to experience the refreshing Muak Lek Waterfall and diverse plant species throughout the week. For those wishing to photograph flowers or enjoy a peaceful atmosphere, it is recommended to arrive in the morning to avoid the intense midday sun and breathe in the fresh air before the crowds increase later in the day.
