Cutimbo is a tiny settlement some 30 km from Puno, in the Peruvian Altiplano, mostly visited on a short daytrip. Although the ruins at Sillustani are greater in most aspects, they also get loads of visitors. Come to Cutimbo, and you could spend hours, all by yourself.
Vans depart from Puno as soon as they fill up, usually every 20-30 minutes.
There is no visible commerce around.
You can probably camp here.
