Excellent
The tour guide Ann from GaiaTours was an excellent guide, funny and knew a lot of amazing information about the national park and volcano. It was a low intensity hike as described in the description but your footing could be very instable at times due to walking across lava rocks (imagine walking across a pebble beach). We had plenty of breaks including one break 2 hours into the hike, at a museum to eat in the shade. Hike was 3 hours, plus travel, pre/post hike breaks and photo time. Worth it!
