The park runs five simple hotels (glorified guesthouses, really) ranging from 2500T to 5000T per person (breakfast/lunch/dinner 500/1500/1000T), bookable via the park offices. You can camp for free at one location on each route.
The guesthouses in the park offer full-board, but the food quality is nothing to get excited about. Bring own supplies if camping.
Typical prices from Outfitter KZ for a two-day trip range from 60,000T to 100,000T for transport (up to four people) plus around 10,000T per person for accommodation, food and park fees (less if you camp).
