Luggage and bags:
This is a backpacker's park and having one will enable you to move around the park more easily and much more cheaply.
Clothing/Shoes/Weather Gear: Hiking boots are a luxury but one you'll be glad you have when clamoring over rocks. Strap sandals are great for day hikes and at camp. Long pants and shirts are nice to keep mozzies at bay but didn't really see so many of them. Didn't need rain hear at all but did have it. Bathing suits truly are a must. This is a great place to swim.
Toiletries and Medical Supplies: Sunscreen and mosquito repellent are musts though the latter was not needed when we were there in February 2010. It was a very dry year in Colombia and hence not so many of them.
Photo Equipment: A wide angle is great for bringing things into the foreground of your photos to make them more interesting. A great zoom comes in handy for capturing all the wildlife you are likely to encounter. I was very happy to have one with image stabilization as many of these opportunities were in low light.
Camping/Beach/Outdoor Gear: Our tent finally came in handy, saving us from renting one or having to spend our nights in hammocks. Mats and sleeping bags made our stay more comfortable. A backpacking camp stove saved us money on eating out especially since we had food left over from an earlier trek!
Miscellaneous: Thanks to D for being a great beach-combing mate. She deserved this little break after completing both the El Cocuy and Ciudad Perdida treks. Bruise or no bruise, she still looks great in a bikini too. ;)
Luggage and bags:
For one day visit of the park, a small backpack to carry water, snacks, sun protection, camera..., is most suitable.
Clothing/Shoes/Weather Gear: The park offers great hiking possibilities so you'll need a pair of comfortable hiking shoes or sandals. Shorts and t-shirt will be fine most of the time. In the evening better wear long trousers and long sleeves, preferably light colours, as the mosquitos can be quite annoying. Don't forget your swimwear and a pair of flip-flops for the beach! You will be out on the sun a lot, so wearing a hat might be a good idea.
Toiletries and Medical Supplies: There is no pharmacy around. Make sure you take first aid with you. It gets sunny and warm all year round so bring a lot of sun protection. Also take along a good mosquito repellant. You don't need malaria pills in the park. You do need a yellow fever vaccination but it is not usually checked.
Photo Equipment: Take all photography (and filming) accessories with you as you can't get anything there.
Camping/Beach/Outdoor Gear: Bring snorkeling gear with you as there is lots to see. You can get it very cheap in Colombia and use during the whole trip. If you stay overnight you can either rent camping gear or hammock, or bring your own (which is especially recommended during the high season when they might run out of it).
Miscellaneous: Don't forget to bring your passport. You need to show it at the entrance to the park. Always wear sunglasses to protect your eyes from bright light of the sun. Small flashlight might be useful if you stay overnight. Food and drinks are somehow more expensive here so bring some snacks and water (you can get them in the small shops outside the park). But you are not allowed to bring any alcohol in the park.
Luggage and bags:
You need to be prepared before going into Tayrona. If you are staying in Taganga before leaving, most places will let you store your luggage there while in Tayrona PNN. If you have a garbage bag or mesh covering, this is useful to keep moisture, water, dirt etc. from getting into your luggage.
Clothing/Shoes/Weather Gear: BRING WARM CLOTHING for the evenings as they get crisp and freezing cold if staying in the upper hammocks in Cabo San Juan. Blankets and sleeping bag highly recommended and/or warm coat with hood. Socks and proper footwear if you plan on hiking to El Pueblo.
Toiletries and Medical Supplies: Bring toilet paper! It is not generally provided. And of course regular items for washing up - be aware that the showers are open, mixed and public so nudity is not really an option unless you just don't care (keep in mind Colombia is not as nudity-friendly as some European countries). There was a nurse station at Cabo San Juan but it was unoccupied when we were there so bring first aid kit.
Camping/Beach/Outdoor Gear: If you have your own tent or hammock you can bring it into the park and pay a nominal fee to string it up/set it up on one of the two campsites. You are not allowed to burn fires so don't bring food that requires cooking. I recommend that one person bring a 5 L jug of potable water for their stay as well as as much food as you can carry/fit/be bothered to take to reduce your costs and of course, satisfy your cravings as options are limited. Crackers, chips, tuna, fruit, dried meats etc are good options.
Miscellaneous: If you have it, bring your own snorkeling gear. Sunscreen and the like, if available at the store, is expensive so bring your own.
Luggage and bags:
A day pack is all you need for a couple of days. You carry in and carry out so the lighter the better
Clothing/Shoes/Weather Gear: Tevas, tennis shoes or boots. ( I wore boots on the trail since that is all I had but only wore then half the way) I went barefoot along the ocean trails. Depending on the weather a long sleeve shirt will help with the bugs and might keep the chill off at night.
Toiletries and Medical Supplies: Mosquito spray, sunblock, toilet paper and other basics..less is better.
Photo Equipment: Take an extra battery as it may be hard to charge one at the camp sites..I did not try
Camping/Beach/Outdoor Gear: Bring a tent if you want. I used my towel as a blanket when it got a little chilly at night due to the rain.
Miscellaneous: If you want to try and snorkel out past the surf a mask/fins would be a good idea.....too bulky for me so a mask would be the most I would bring. Also might want to bring snacks if you do not feel like paying park prices which were in the case of beer 25-50% more...I saw my share of whiskey bottles that were packed in....Johnny anyone??????
Miscellaneous: If treking in Parque Tayrona, make sure you bring ample water since there are few or no water sources in the area. The trails are easy to follow. However, I did got lost once, but only because I stray off the beaten path :). All things happen for a reason though. I found a cave with some kewl animal bones that made for a good picture.
