We didn't feed other people's ponies, you never know when they might be on a restricted diet because of laminitis or something. All the ponies got from us was a pet on the nose and neck :-)

We spent a bit over an hour at Grabrok, doing the hike up and all around the rim, with stopping time for photos. It's about a mile around the loop.

The white buildings really stand out against the dark Icelandic rock or the green/gold of the fields. It's a very cheerful choice for a landscape that can look pretty bleak, and I approve!
