An ecoconscious adventure-tour agency and shop run by the knowledgeable, English-speaking Vlado Soto. In addition to trekking tours away from the crowds, it organizes mountaineering, mountain-biking and river-running trips. It's one of the few shops selling decent topographical maps of the area and is a venerable source of information for those hoping to explore this region on their own.

Be careful of copycat travel agencies that use the Colca Trek name and/or web addresses that are similar to the agency’s official site.
