We (me, DH and DC aged 15 and 12) are visiting Iceland for a week this coming August. EasyJet have brought our outgoings flight forward by a day, which means we're there for a extra day and night. I'd really like to spend the extra day in the Reykjanes peninsula looking for lava and mud pools. Does anyone have any experience or tips? We'll have our own hire car and we're staying by the Blue Lagoon for a couple of nights.
