Alejandro Velasco Astete International Airport Car Rentals: Best Rates & Zero Hidden Fees

Your US license alone won't cut it—Peruvian law requires a Spanish translation or an International Driving Permit (IDP). The IDP is the safer bet since police checkpoints are common, especially on routes to Machu Picchu and the Sacred Valley. You can get an IDP through AAA before departure (about $20). Without it, you risk fines of 200-400 soles (~$55-110) and possible vehicle impoundment.

Yes, most agencies require drivers to be at least 21 years old. If you're under 25, expect a "young driver surcharge" of roughly $15-25 per day—this is standard across all major agencies like Hertz and local companies. Some agencies in Cusco set the minimum at 23 instead of 21 for 4WD vehicles due to mountain terrain. Budget accordingly: a $40/day rental can easily become $60-65/day with surcharges.

Cusco's altitude is no joke—your engine will lose 20-30% of its power compared to sea level. Turbocharged diesel vehicles handle it better than naturally aspirated gas engines. Avoid aggressive acceleration on steep climbs (yes, the road to Rainbow Mountain is that steep). Let the engine warm up before pushing it, and watch for overheating on long ascents. The thin air also means brakes work differently—downshift to engine-brake on long descents rather than riding your brakes.

For most tourist routes (Cusco to Ollantaytambo, Pisac, Sacred Valley), a 2WD sedan works fine—the main roads are paved and well-maintained. However, skip the sedan if you're heading to Rainbow Mountain (Vinicunca), Humantay Lake, or the Sacred Valley's more remote corners—those require 4WD with high clearance. Wet season (December-March) can wash out even main roads, making 4WD near-mandatory. Budget 200-400 soles ($55-110) more per day for a 4WD, but it's worth avoiding a stranded rental.

The wet season runs December through March, and yes, it complicates driving significantly. Daily afternoon downpours are common, causing landslides on mountain roads (especially the PeruRail crossings near Ollantaytambo). Road to Rainbow Mountain becomes treacherous or closes entirely. If you must drive during these months, leave before 6 AM to avoid afternoon storms, and confirm road status with your rental agency—local knowledge beats GPS in these months. Most agencies include free 4WD upgrades during wet season anyway.
