I will be in Columbia for a week in April- traveling solo- I fly into Bogota late on a Saturday and plan on staying there for the evening then flying directly to Cartagena in the morning-unless there are things in Bogota worth seeing? Also I plan on spending my time in the Cartagena area the rest of my trip until the next Saturday when I must return to Bogota for my trip home- Is it worth it for me to take my time away from the Cartagena area to visit Tayrona National Park? I understand it is a 4-5 hour bus ride and im a little anxiuos about sleeping in the park as a solo female traveler? any suggestions? I would love to see Tayrona but am just wondering about time and logistics?
