In Colombia, Suecsa is a small town an hour bus ride outside of Bogota. There you can stay in a beautiful climber's hostel that will cost peanuts. Your climbing, gear shop, and food is all located within walking distance. The main sanstone cliff is about 1km long with sport and multi-pitch trad. There are plenty other great sport crags nearby.
La Mojarra is a remote cliff outside of Bucaramanga. There is a great climbers hostel there situated directly on top of the cliff comprised of 80+ stellar sport climbs on perfect orange fine-grained sandstone. The place is a paradise.
Colombia and Colombians are incredible.
If you need more info message me, and also start learning Spanish in your spare time. It is not necessary but knowing a little will make your trip exponentially better. Get some audio books to listen to while driving to your local crag.
