Almost any tour to Laos includes some kind of excursion. In fact, this is an excursion country with opportunities for active pastime. Holidays in Laos can be creative, meditative or adventurous. You have to be prepared for the fact that this country is not rich at all, but is already spoiled by tourists.
There are many guests here, and a full-fledged infrastructure is being formed for them. Reviews about excursions in Laos primarily mention the capital of the country, Vientiane. This is not a very big city, in which there is not a single noticeable skyscraper.
But there is the Mekong River, and interesting rafting is possible downstream or upstream. Such tours cost from 10 USD depending on many factors, ranging from distance, to the boat you take for sailing, and the presence or absence of a guide. Of course, a normal full-fledged voyage along the Mekong or its tributaries will cost 70-100 USD.
Due to the complexity of the flight and distances, the cost of tours to Laos is not too low. But here, too, options are possible. If for a tour that will include the sights of Vietnam and Thailand, you will pay from 1500 to 2500 USD, then for tours to Laos without neighboring routes you can pay up to 1500 USD.
Prices for excursions in Laos itself are not too high. So, for visiting the Pak U caves they ask about 40 USD. A visit to the temple complexes in Luang Prabang costs from 20 USD. You can visit the elephant park in the same city for 70-100 USD.
Religious tours around the country are quite popular, so explore the sights of Laos and choose which temples you want to visit.
