Day 4: Masaya and Granada
We left Las Penitas early so we could get on the road to Granada.  However, on the way we passed directly by Vulcan Masaya, which we could see from the road was actively smoking.  The guidebook didn't have much to say about it, so we veered off the main highway to check it out.  After checking in the main entrance and receiving our hardhats, we were on our way.  There were a few strict rules about head gear, exit strategies, and parking.  An explosion the previous April had spewed quite a few rocks at some tourists, so they weren't taking any chances.
