I climbed Pena de Bernal with these guys and strongly recommend the place and the service. Simeon's communication before and after was impeccable and the guide he provided, Carlos, was as conscientious as he was warm and I always felt in good hands. Bernalina was amazing -- 250 m, 6 pitches, perfect level of difficulty for an intermediate climber like myself. The rock and the weather couldn't have been better. I'll be back!
