Luggage and bags:
There are hundreds of tourist shops selling amazing trinkets, so make sure you have some room in your baggage. Also, a good back-pack or shoulder bag is ideal for taking your belongings with you to go exploring.
Clothing/Shoes/Weather Gear: If you are going in the summer months it can get extremely hot, so light coloured, loose fitting clothing is a must. Make sure you take a hat with you, preferably a fully brimmed hat rather than a baseball cap.
In the winter months the rain can get horrendous, but it is still usually very warm, so light rain coats are highly recomended.
Toiletries and Medical Supplies: Sun cream is a must for the summer months. Mosquito repellent and bite treatment cream is also necessery. If you venture off the main roads, as you will undoubtadly do here, either make sure your legs are fully covered or bring plasters and antiseptic wipes incase your legs get scratched by the dry twigs and roots that stick up out of the ground.
Photo Equipment: There are some amazing views here, and to not bring a camera would be a disaster
Camping/Beach/Outdoor Gear: Some swimming in the sea is a must-do here, so bring swimming clothes, beach towels and any snorkeling equipment you have.
As the sun is pretty strong here always remember about wearing a cap, sunglasses and putting sunblock.
If you go to the pebble beach on the western side of the island, the swimming shoes will be needed.
Many beaches in Rhodes are rocky (not sandy), so if you have sensitive feet, bring swim shoes.
Camping/Beach/Outdoor Gear: Strong sunscreen and mosquito repellent are very necessary in Rhodes. Even if you don't burn easily, you should still wear really strong sunscreen. You can bring mosquito spray or maybe some cotton pants and long-sleeves to wear at night.
Luggage and bags:
Depending on your means of travel. Rental cars can be a bit small (Fiat Panda like) Our baby buggy just barely fit.
Clothing/Shoes/Weather Gear: Multilayer clothes
Toiletries and Medical Supplies: More or less everything available
Camping/Beach/Outdoor Gear: Camping officially not allowed. However we saw some tents and outdoor stores.
Miscellaneous: Bring a flash light. Power outages seem pretty common!
Clothing/Shoes/Weather Gear: you should bring some special boots (might be swimming boots tourist use) to walk along the shore...it really hurts to enter the water without having any feet protection! :)
