No it wasn't exactly luxury. We have a horse trailer with small living quarters. Small being the key word here, a set of bunk beds, small shower, small sink and a toilet. We cook outside weather permitting. Its still better than sleeping in the back of the truck
Its pretty comfy for about 3 days then I start getting grumpy. If its nice enough to keep the windows open and we are someplace where we have to leave the horses in the trailer at night, Vida's head is about 2' from my head when I'm trying to sleep. I discovered she is a night owl and will stand and chomp hay till the wee hours of the morning
Horse Heaven has 2 fairly large pipe pens with each campsite, so I slept good while there. They have VERY nice cabins each with large corals and barn too, but a little pricey for us. We are talking about splurging and getting a cabin for our wedding anniversary next year. Its about 300 miles from us or 6 hour drive if thats easier. It is part of the Ouachita (pronounced "wah-shi-tah") national forest. Talihina is a little town of about 1000 people so not much to do there besides ride horses.
Kansas twister, its in SE Oklahoma just across the state line from Arkansas. Here is their web site http://www.horseheavenranchresort.com/
Its a really nice place and friendly folks.
Jazzrider, It is really great that so many of the state and national parks here in the US are open to equestrians. Many have areas designated for "horse camping" with cleared trails and horse friendly campsites, some have picket posts, hitching posts or corrals. Do you have public areas set aside in Australia? Maybe you could get something going there to open them up to equestrians after the EI quarantines are over.
