A day trip lasts from when you are picked up at your hotel around 7 AM until you are returned to your accommodation in the early afternoon at roughly 2 PM. Picnic breakfast and lunch are included, as are a few drinks. Your guide is very experienced and is well-trained. You can enjoy the fantastic nature of the river, look out for birds and watch the animals of the National Park that come to the water to drink.
You can also book multiple-day canoeing tours with overnight.
