It became one of the most memorable trips in my life thanks to such an amazing place! I recall my experience surrounded by trees, the sky and birds' tweets in such a cute den. If you like adventures I 100% recommend you to stay. You need to go up a ladder high and the 'house' occasionally swings a bit, so if you're afraid of height I don't recommend though. I stayed in July but it gets chilly in the night, I strongly recommend you to bring warm blanket or sleep bag.
To my surprise, this place has wifi and outlet, you can keep instagramming your experience from the den! I really liked the location too. It's in the middle of the woods but close enough to the west side of Santa Cruz.
