Brochure advertises a 90 kg weight limit on a "pathfinder ride", that said the brochure has multiple ride types leading you to believe that might be a weight limit for an all day or particularly extreme trek. To be fair I am probably around 91-92 kg. My husband weighs more than me (probably around 93 kg) but he is a tall man and I am a short woman who looks round. They took one look at me and declared that I would not be permitted on the horse. They said "how much do you weigh?" So I told them in pounds, later check shows the number I told them was actually right at 90 kilos, they said "we don't know pounds but you are too big". I said, what about my husband and pointed to him. They replied he "was ok", even after i said "he weighs more than me!" Looking at the other riders there were clearly several tall men with round stomachs that weighed more than I did, but perception is everything. They were surprised when our whole party decided to leave rather than me just leaving alone in shame. 90 kilos = 198 lbs, if they were enforcing this limit universally they'd lose many customers but they weren't exactly having people climb on scales, but certainly many tourists, particularly men, exceed this weight.
So if you look fat, don't bother showing up here. Honestly it would serve them right if people just didn't show up in general. They of course did not speak good enough English to even discuss the situation with them, all they said is "our horses too small for you, very dangerous" and sent us on our way. If it really is dangerous for 90 kilo riders, tall or muscular men also beware!
