Tip 1: Set up a tarp A tarp underneath your camping tent helps to prevent moisture from entering from below. Additionally, you can set up a small tarp as a little roof that shelters the entrance of your camping tent. You can then get in and out without getting wet whilst opening or closing the zip. Also, the rain won't enter your tent every time you open the door. If you have a large tarp, you can cover a bigger area so that you can have some sheltered area outside your camping tent. Especially when it rains for days, you will appreciate an occasional walk outside. You might even be able to light a fire underneath your tarp. When the weather is nice, such a tarp provides great shelter from the sun. Ads by Google Tip 2: Do your seam sealing Check carefully if your camping tent requires seam sealing. If it does, make sure you have what you need, and do a proper sealing. This does take a bit of work, but it will prevent moisture from entering your tent uninvited, keeping you and your things dry even in the rain. Many camping tents feature a bathtub floor which has no ground level seams that might leak. These tents require less seam sealing and save you some time. Tip 3: Set up your rain fly Make sure you know exactly how to set up your camping tent's rain fly, and that you have it with you when you go on your camping trip. Don't wait for the rain to set it up. Yes, it's a rain fly, but it's clever to set it up in good weather already. Rain often starts out of the blue, and you don't want to rush out in the middle of the night into the rain to throw the rain fly over your camping tent.
