Cartagena...
The city truly is amazing - all that the guide books say, and more. Truly is Colombia's jewel. The first (non-local) settlers and construction date to the early 1500's. Mostly Spanish.
It's a walled city, with several miles of walls 10-ish feet thick, and up to 20' feet tall, with forts at strategic places; the most gigantic Spanish fortress ever constructed stands at the mouth of the key inlet (pictures below).
The Spanish resorted to the walls/forts/fortress because during their years of looting the country's gold and other treasures (which they amassed and stored in Cartagena prior to shipment to Spain), they kept getting attacked (successfully) by pirates (the most successful and famous was Frances Drake).
After the walls and fortress, the city never fell again. Easy to see why!
Couldn't resist including one with me...
Beneath the fort's surface there's a maze of tunnels that connect the living quarters, mess halls, supply rooms, medical facilities, etc., and also provide shortcuts for fast transitions to/from any part of the structure. The tunnels are cool with a constant breeze - I'm sure they provided welcome relief from the hot temperatures on the all-rock surfaces above.
If you look closely at the church door on the left, you'll see one of the utilitarian doors.
Cartagena is actually 3 cities: the lovely old walled city; the new city of skyscrapers and haciendas; boutiques and gourmet restaurants; casinos and other toys for the mega-wealthy; and the "underbelly" where the local and indigenous people live in abject squalor. The city is advertised as safe, and it is - in large part because each and every day (and night) there are 2,000+ armed police patrolling the streets. Outside of the city, it is definitely not safe - even for the police.
Lots of art in the plazas and parques.
The ocean is awesome - always a breeze blowing. It would be quite intolerable here if that weren't the case, as it's pretty hot, but with the breeze, seems moderate. The beaches are a mixed bag - they're beautiful, but - the good news here is that they're all public - the businesses and condos are set back, across the road. But the fact that they're all public is the bad news, too - they're public to every vendor wanting to hawk some wares.
The two main beaches within walking distance of the old city are Bocagrande (above - ocean-side) and Castillogrande, (below - bay-side). The day I took the beach pictures it was morning and overcast. When the haze burns off, the water is tropical turquoise.
It takes me a day or two in a new place to find my "level" - it was harder in Caartgena than in most places because it's one of the wealthiest cities in the world, and the shops and restaurants reflect that. But I did find my favorite street vendors, a great book store, an unbelievable restaurant with 5-course dinners for $6, a decent grocery store, and a quiet park. Those finds, combined with my hostel (large room with kitchen privileges) made for a great time. Even so, I was more than ready to leave - 6 days on a budget in this type of place is about 2 too many.
