Hiking 2:05:56 [2] 6.38 km (19:45 / km) +197m 17:06 / km
Went up towards Monte Teide (3700 m, an extinguished volcano and highest peak of Spain!) but stopped along the way and did a loop around the volcano Chinyero which erupted in 1909 and we walked around the caldera mostly in a beautiful pine forest but occasionally traversing the jagged lava fields. It was a most enjoyable, easy hike on a well-marked trail. Lots of people on the trails most of them Germans, some Swiss!
A sunny day but still some cold wind occasionally. Had a view west over the Atlantic to the neighboring island Gomera and La Palma.
Still having back pain.
