Traveling Essentials
After quite a lot of trips to many different places, I have learned that there are few essentials that you have to carry with you no matter where you go.

1-Power Bank
During my rutine, I do not use any power bank because the battery lasts me a day generally. However, during any trip you go, you use your phone almost everything. You may need to charge you home once or twice a day. In this case, there are two options you can go for. First, you can sit in a Cafe which has to have a charger for more than an hour depending on yourhow long it takes to fully charge you phone and you have to buy something for it. It is not a bad solution because during the lunch or snack or when you are tried, you get in somewhere and sit for a while but there are some disadvantages that you may face because you are not the one who decides where to sit but your phone because in US(let's say LA, there is no charge place even in Starbucks.) I had to lost 2 hours of my day trip to LA just because I need to charge my phone. It is sucks! For the second choice, you can decide when and where you wanna sit any cafe or restaurant depending on your own preferences and charge your phone whenever it needs to be charged. You can listen music how long you wanna listen. However, I recommend you to buy a powerbank that can charge your phone more than one time like 20000 mah. (It may be heavy be careful) However, when you buy a powerbank try to buy lighter one because you will be carrying it all the time.

2- Sun Glasses
I don't know whether you generally use sun glasses but they can be essentials because you will be out and are walking all day long and the sun can disturb you while you are trying to enjoy your trip.

3- Passport
Even though you are traveling in the same country, I recommend you to take it because once way back to Paris, police stopped the bus and wanna check all passengers password.

4-Cash and Card

There are many people who hate using cash but cash could be essential in most if the cases because some places which are popular do not accept card or in case you are thursty and wanna buy a bottle in bus, driver may not accept card. There could be many other examples but even thought here is no coin place in your wallet, have some coins with you all the time + some cash.
5-Water Bottle

It may not seems like an important one but for me it is. I am more likely to forget drinking water during my trips because you are full of other things and out of your routine but if you do not drink water then you tried much easier, you may have a headache and feel dizzy. Let me give you an example, one of my friend did not drink much water on our trip to Death Valley and she had to turn back to RV early and had a headache all night long. She couldn't join the activities we did that day. During the hiking or traveling, water is essential. Because seeing new places is great but being healthy and happy is much more implrtant because you should remember how great the places you went not how bad you felt during the trip.
6- Jacket
This is important because even though you check the weather and it is saying it will be sunny all day, you may need jac
ket because of weather change. You may be laughing at me right now, it is fine as long as you have a jacket with you because once I did not bring anything to LA and I thought that it won't be problem since it is LA. At the end of the day, My fingers were purple because of cold. Trips are not for suffering but having fun.
Enjoy!
