This is an ideal place for backpackers who can take care of themselves. Do not expect luxury restaurants, souvenir shops or any guided tours. So it is important to prepare yourself carefully (e.g. it is not a rule that afternoon you will get a bread in local grocery store or that there are lunches served in the inns. So take with you what you may really need.
But the result of the trip could be amazing. Nature is really not too much touched by tourists. If you wan t to observe dark skies - this is an ideal place. Of course, having in mind weather forecast. And watch the forecasts also before hiking into the mountains. There are no shortcuts for return - and the tours are pretty long.

This national park is especially famous for the dark sky observations. We went there in the early night and spent several hours looking at the stars, it was truly amazing experience. Must do for city people who don't get a chance to see such sight due to high light pollution. Definitely recommend a trip when you're around.
