My wife and I plan a 10 day vacation to BI in June. We had been planning to stay several days in Volcano to be near VNP, but a friend here at home advised against it. She said that she had visited Volcano last summer and that the toxic fumes were bad. She advised staying in Hilo and just visiting during the day. I checked some websites which seem to confirm that the level of fumes has been higher lately. Should we be concerned about staying in Volcano?
