This place does not have electronic ATM, and they do not accept Cards! Cash only to enter the reservation! $15 for sightseeing is what I was charged at the time. The Nambe Falls is interesting. The overlook hike took 10 mins 1 way, beware the water had a strong ammonia sulfate smell. The Lower Nambe Falls trail requires wet shoes and wear short. The water can get up to 2 feet while walking towards the Nambe Water Fall. There are sharp rocks when treading the water. It took me about 17 min before you're required to get further out under the water fall. I stopped because I didn't have spare shoes, and I was only visiting and trying to stay dry, which I did. The rest may take another 3 - 5 mins to get to the Nambe Water Falls? There was some traffic of people if it got busy or a lot of people just in the way.
