After reading the reviews on Tripadvisor I felt it's going to be A good non zoo experience. First of all the drive up there is as many roads in BG, one lane for both directions including numerous trucks passing so keep that in mind, after that road you get to a gravel road which isn't the worst I've seen but still not an easy chill drive. Once you get to Rila Fun Park keep going you got another 2km up the mountain. The place itself is far from my definition of a park all you can see is huge high fences, electric no less surrounding the whole place, If you have any physical disabilities the terrain could be challenging with sharp uphills downhills. The bears are separated in different sections not sure why but they seemed lonely and bored. I saw 4 bears: one was napping right as you walk in, the second one brought me to tears as he was pacing back and forth the whole time we were there it was very hard to watch and reminded me of those horrible zoos where caged animals get so anxious they keep pacing frantically. Sadly I couldn't get to the guide to ask about it since there were many people there who speaks Bulgarian and she answered their questions, so I might be wrong with my observations but most likely I'm not. The third bear was bearly walking he was trying to walk down the hill but kept stopping and looked kind of limping. The last bear was by the parking lot chilling and eating he's the only one who looked ok. I know it's a sanctuary and I understand most of the bears had physical issues abuse an trauma before getting there, if any information would have been written through out the park in English we might have understood more but I didn't receive any written info when I got the ticket. I must admit those fences makes you feel like they're in prison. If you love animals you probably won't enjoy the experience. Fee is 6lv I don't recommend this place.
