Pet-Friendly Private Pension Campsite Near Seoul

I visited a newly opened private pet-friendly pension on the way to Yongmun Mountain in Yangpyeong. There's a large yard where kids and dogs can run around together, and in the evening, you can enjoy a barbecue and a camping atmosphere, and it's great to be able to rest quietly just by ourselves. I heard there's also a stream flowing behind it. I should visit again when the weather gets warmer.
