Sad to get rained out of this one as I've been looking forward to finally getting here for 1-2 years now. From the little I saw in the socked in conditions, I will have to be back. Looks like a really fun area to explore. It poured, and the wind blew all night long and everything was damp, so we bailed after 1 night instead of our planned 2.
Road report: Tulameen FSR is perfect with no issues. Weekdays watch for logging trucks- we saw a lot as we drove in Fri. They were very courteous drivers and slowed down to avoid dusting us too badly. The Spur to the TR is ok for the first few km but there are no pullouts, so unless you're in a good 4wd and not too attached to your paint job (Alder is encroaching) then park right after the 19KM Tulameen FSR Bridge and just walk- it didn't even add an hour for us. The hike in to Illal is nice and short, so this is ok. Everyone we encountered parked before the Spur- even those with 4wd.
I guess it can't all be sunshine and alpine lake swims, but I can't help feel disappointed. photos I've seen from the Fall here look excellent, so perhaps I will have time and weather to try again then.
