When a luxury resort is not enough to "get away from it all," a travel company is offering the ultimate vacation on a remote island with no hotels and no guides — and where you have to fish for your own food and build your own shelter.

While it might not sound like the most relaxing vacation, Spanish company believes its week-long getaways are the perfect way to escape and "lose yourself in nature."

With its "Adventure Mode" vacations, travelers can feel "like castaways" by staying on. Travelers sleep in tents (or tree houses, basic cottages or bungalows) on stunning beaches surrounded by jungles and wildlife, and fish and cook their own food. Survival gear, canoes, fishing equipment, and even machetes, will be provided.

Intrepid adventurers can also choose to be totally alone on the island, with no guides, but the company ensures staff is readily available in case of emergencies, the company says.Rates for the Adventure Mode vacations start from around $88 per day, according toDocastaway'swebsite.

"I wanted to give other castaways the opportunity to experience the ,’ Docastaway creator, Alvaro Cerezo, told the Daily Mail.

Not into feeling like you're in a Survivor competition? Docastaway also offers a "Comfort Mode" option where travelers stay in comfortable private villas and cottages with buffet-style restaurants. The vacations will still offer isolation, though, with many of the destinations located in remote islands with private entrances and private beaches. Each island is also limited to one client (or couple) at a time to maximize the feeling of isolation.

Although Alvaro told the Daily Mail that the company advises clients to stay no longer than two weeks, in one of Docastaway's remote island destinations, Siroktabe in Indonesia.
