This was the absolute most perfect spot for a family reunion! 14 of us (ages 5-75) from all over California and Oregon met up at Otter Space. We stayed in the Yurt, tipi, blue and pumpkin cottages, and the upper barn. Our home base was the yurt as it was the perfect location to the river, large enough deck for all of us to eat our meals, and full kitchen to prepare food.
Everyone in attendance loved Otter Space. We spent our mornings having coffee on the deck of the yurt or in our private accommodations (all equipped with stove and kettle); afternoons on the beach relaxing, floating or playing in the river, or fishing; evenings playing volleyball or other sports on the meadow (usually with the hosts kids who were sweet and friendly and overall fun to have around); and nights having bbqs at the yurt or bonfires on the beach.
Things to note:
1. the hill from Otter Space to the river is quite steep - 2 folks in our group with mobility problems needed to be driven down but everyone else could walk just fine including the 5 year old. We drove our truck down to shuttle those that needed it but the hosts also generously offered to give rides when needed
2. the tipi is totally open on the bottom so we were visited by lots of bugs, a snake and frogs, so if you prefer to minimize wildlife sleeping with you then avoid the tipi, there are plenty of other options. I personally loved the tipi because it felt very rustic and remote and when my teenage freaked out from the bugs and went to the upper barn with his grandparents, I had the tipi all to myself which was perfect!
Joe and Wendy and the kids are extremely helpful. They were always available if we needed anything but careful to give us privacy in our spaces.
Prior to the trip I had tons of questions for Peter and he always responded immediately via email, text or phone.
Overall I can't recommend Otter Space enough. Our entire group kept saying how lucky we were to find this gem, and we already talk about coming back!
