Are you asking "Have you (ever) been somewhere beautiful?" I think that's what you're asking. "I'm gonna...." is a really informal style of asking. Are you sure you should be practising bad grammar and style? By using it you might confuse other students, particularly beginners. So... you're going to take a break from your daily activities. Good idea! You decided to go somewhere nice. However, you don't know where to go. Hmmmm. Let me think. What about a quiet beach? For a long walk. It's nice and cool with all those sea breezes. I'm going to the beach later, with my dogs, for a long walk. There'll be grey skies and a fresh wind, and we'll have birds and crabs for company.

Sorry to be critical, but your sentence needs a serious revision. I understand what you want to say, but it is completely chaotic. "Do you have been gone" makes almost no sense at all. You have actually put two different sentences together. "Do you have...?" asks about possession. "Have you been (somewhere)" asks about experience. We add "ever" to the sentence to mean "at any time in your life". "Gone" doesn't fit here. Look up the difference between "have been (somewhere)" and "have gone (somewhere)". They are really two different things. "...that's have" makes no sense either. You need to use "that has (something)" or "that is (description)." Lastly, we have "...a beautiful places." The problem is, "a" means one, but "places" means many. So which is it? I agree with Moira's neat and clear correction: "Have you ever been somewhere beautiful?" I'll just rewrite the rest of your sentence properly. "I'm going to take a break from my daily activities and I've decided to go somewhere like this. However, I'm still confused as to where I should go." To second Moira's advice about slang and lazy forms, if you are making basic mistakes with spelling and grammar, you should avoid any slang forms completely. It makes your natural mistakes look worse, and it tells me that you don't even care. There's nothing wrong with writing it properly. :) Anyway, I guess you're looking for a place with natural beauty. I'm in a landlocked country, so my best options are to go into the forest or up to the mountains.

Oh, right Miss Moira. I think I must get more practice before telling something in English. By the way I often say it because I've got influence from my friend who always use in informal style. I know that is absolutely wrong and its kind hard to make up to being formal style. Hehe. But I promise I will practice better than now. Yap! I want to going somewhere nice. Beach? It's sound good. I can walk on the sand and feels a breath of air. But, Imn't joy about sun in the afternoon, I don't know why exactly. I merely could go to beach in the evening. What your favorit place to spend your time?
