The hike took us from sea level to about 2500ft but the trail was in good condition so the hike was great! The Quill is the volcano responsible for forming much of the island but has been inactive for hundreds of years so it's all grown up with jungle. We were under tree cover most of the way which helped with the heat and by the time we left Panorama Pt. (highest point on the western side) it was 5p and the sun was on its way down.
Awesome hike-- would reccomend it to anyone!
