Really amazing. The mountaintop forest is really wonderful, and the air is fresh and cool. Very very quiet with birds and other wildlife around. The crater was clouded over when I was there, but still a very cool experience and worth the trip. It sounded almost like an airplane near the crater from the gases escaping the fumaroles (vents).
Logistics - I got there at 1 pm (online ticket is a must!), no queue, small parking fee, only a couple dozen people there for the last part of the day. Nice gift shop & cafe. I’ll also mention that it was nice to drive through the farms/economies dependent on the montane climate - coffee, strawberries/fruit trees, and trout. Nice clean mountain air.
Be aware that mountain access may close suddenly due to volcanic activity as happened a week ago.
