A great outing in Goa is a trip to the Dudhsagar Waterfall, which is one of the most popular natural attractions in the area. The falls are located in a tropical jungle near the Goa-Karnataka border, and are surrounded by a network of gently flowing streams and pools. Swimming, hiking and picnicking are popular pastimes at the falls and the deep pool beneath the falls is a favourite nature spot. The waterfalls are among the 100 highest in the world, and visitors who take the difficult climb to the top will be rewarded with breathtaking views of the Western Ghats' wooded mountains. There are usually monkeys to be found in the jungle and around the falls and they tend to be very tame because tourists often feed them; feeding the monkeys is prohibited because they quickly become a nuisance when they associate people with easy food. They are fun to watch and interact with but be cautious with your food and possessions as they may try to take something. The most common way to get to the falls is to take a fun 30-minute Jeep ride from the entrance to the jungle, but some intrepid travellers choose to walk along the train rails from Castle Rock Station. The hike is beautiful but it is over eight miles (14km) and should only be attempted by the fit.
