We recently experienced a day on a trip called "Paulina Plunge". This is a day event based on mountain bikes, mostly downhill, a bit of hiking and focused on accessing a series of waterfalls on the Paulina Creek.
ON THE PLUS SIDE: a) our ten year old had a blast and it seems best suited to the age plus or minus two or three years; b) our 18 year old enjoyed the biking piece- but he loves everything biking c) the remainder found it disappointing but not a complete waste of time
ON THE NEGATIVE SIDE: SIGNIFICANT LACK OF SAFETY DISCIPLINE. While our guide and the lead guide were very explicit speaking about risks on bikes, going downhill too fast, etc. the following negates this effort in our opinion. a) on the phone and on the website, it is noted to be a “SAFE, FUN FAMILY EXCURSION FOR ALL ACTIVE AGES” with no obvious discussion about risks; b) there is steeper terrain and some uphill runs which are not disclosed until on the bikes ready to go; c) our guide took little effort to assure that his entire group was assembled prior to leaving a location. No counts or other disciplines normally expected in such an outing; d) helmets were note required over age 16 and guides did not consistently wear helmets themselves (poor examples); and e) most importantly was a lack of systematic approach to major accidents.
SPECIFIC EXAMPLE: On our ride a mid-aged woman took a hard spill on her bike near the end of the day (fortunately she DID wear a helmet). She appeared to have a significant concussion based upon her response to questions- did not know where she was, what day it was, a bit confused on who she was and did not appear to recognize her husband. Clearly in shock and woozy- later found pain in her shoulder/collar bone area. Our guide was some where in back with our 20 person group.
Ahead was a leader on a motor bike who sat not taking action despite the collection of riders in his view not many yards away until finally we saw him and ran after him. I say ran after because he began to ride away. Screaming and making signs of distress, he chose to ride about a hundred yards to his bus before returning (perhaps for a first aid kit, perhaps not). Upon arriving at the scene the questioning was repeated and it was clear that the woman was not well, likely a major concussion, certainly disoriented. Rather than insisting on going to get the bus to pick her up, he encouraged her to walk to the bus. Probably 200 yards.
Our guide showed up at about yard 150 and probably 15 minutes or so after the accident occurred. He showed sincere concern, repeated the questioning to understand the situation and helped her husband and another man get her to the bus. He checked her helmet to see what it might tell him about the situation. However, that was the extent of it. We did take off rather than waiting for another group to join. No one called ahead to the emergency services facility; the company did not drive directly to that facility but rather to a parking lot (nearby).
No paperwork was filled out, no evidence of any further action to mitigate the risk, to mitigate the outcome of this event to this woman.
Would advise NOT trying this unless they materially upgrade their safety procedures and then only for the benefit of 8-14 year olds.
