Yes, we did not have a dog with us but saw several people who did.

heck no! all streams & rivers are potential for harmful microorganisms.

I think we may have put $5 in a box to park the car.

It is a pretty short hike. Maybe 20-30 minutes. We were in the snow and ice.

I would recommend Red Jacket resort for a possible alternative. Maybe Diana’s Baths for a part of the event not for the reception or picnic since it is a good hike in and out with plain earth paths and rock climbing at the end. Food would not travel well and there are only a few benches at the very end. Red Jacket has a nice combo of possibilities, look at their website for the range of family needs and your big event. Also very close to Diana’s Baths.

Yes -it is perfect but with close supervision

Yes there were a few dogs there mostly little ones who were being carried

It’s very easy!

The walk may be a bit much for a 3 year old but is not impossible. As far as the 70 year old it really depends on the condition of the 70 year old. If they are fit and athletic it should be no problem if they are a bit frail them it may be a bit much.

I’m not sure about accessibility in the winter as we visited in July. It takes 15 mins to walk into the baths - mostly all flat. The actual baths themselves can be climbed to as far as you want to go. We walked into them and explored them with a 7 yr old and a 5 yr old. No trouble at all - just take care whilst moving around the actual rock areas.
