This out and back trail is an old double track that is now almost entirely covered in thick, slide alder. We camped at the south end of Spanish Lake near the "trailhead". The trailhead is marked by a park boundary sign 15m across Spanish Creek near the outflow from the lake. Due to lack of time (and declining interest) we turned back at 2.5km and we never reached the volcanoes.This would be a lovely trail if it was brushed out.
