If you are searching for a romantic setting, one without distractions that truly allows you and encourages you to connect with your partner, then you should consider a stay in the mountains. You can rent a small and cozy cabin in the middle of nowhere and nothing can make you feel more close than that kind of quiet seclusion. It is just the two of you, your shelter, and all of the Earth's creations. You can hike together, maybe find a small lake where you can fish. Away from all of the noise and technology you have no choice but to find a way to connect and entertain yourselves.
