The glass house in the middle of the fern forest is one of the most unique places that I've stayed at so far. It is clear that the hosts put their hearts into designing and building this place. Being an off-grid house, it is unique, modern minimalist, and extremely romantic.
Location-wise, it is super close to the Volcano National Park, so big pros for people who plan to visit the park. However, it is not very close to any big towns. The nearest town is the little volcano town outside of the national park, which has limited restaurants and two general stores that do not suffice general grocery needs.
Comfort-wise, the glass house is small but very tidy, clean, and cozy. Being a house using just glasses as its walls creates an illusion of living in the jungle. The glass walls also define the "heat capacity" of this place: it gets a bit hot during the day when/if the sun comes out, and it gets quite chilly during the night. The host kindly prepared 2 sets of fuzzy blankets, which I absolutely appreciated (I brought enough warm clothes, but fuzzy blankets are just so thoughtful). *A tip coming from my stay is that shower when there is still daylight!* The ambient temperature drops drastically once the sun goes down, stepping out of the shower at night can be quite cold and unpleasant. Also, because the shower is inside of the glass house, the after-shower moisture often gets trapped inside of the glass house after sun down.
Even though the glass house does not have a kitchen, it has an extended deck with a griller, stove, and some basic kitchen essentials. I absolutely adored the deck and being on the deck (for day and night, for rainy and sunny weathers). *Another tip from my stay is that if you are arriving late at night and haven't had time to eat before arrival, bring some cup/instant noodles!* They will save you from a cold hungry evening out sitting on the deck.
The host did a wonderful job decorating the place with lights (Although I kinda wish the nightstand lamps were a little brighter, it was a little dark inside of the glass house to get around when we arrived the first night as we didn't know the place that well yet). At night, the glass house is just magically romantic. I soaked in every minute watching the lights and the jungles from the deck at night. During the day, I loved exploring the plant lives around the glass house and listening to the birds singing hiding in the canopies nearby. The plant lives are so abundant with so many types of ferns and flowers. I even found two bushes of orchids growing on the cutoff tree stem on the right-hand side of the stairs. Although not sure if they landed there naturally or if the owner planted them there. Also sad that they were still young and had no flower spikes when I was there. (Actually, we found that there is an orchid nursery, Akatsuka Orchid Gardens, 5 mins away on route 11 from the glass house. Be sure to check it out if you are orchid fans.)
Overall it was a wonderful stay for me and my husband. The volcano glass house definitely has its kinks to work with, but since we love the backcountry and modern minimalist style at the same time, this was an unforgettable glamping experience for us.
