The Lunderamsa burial site is a beautiful example of a large Bronze Age burial cairn. It is not the more common round cairn but the rarer longer burial mound. It is set atop a large rocky hill in a pine forest with some rocky outcrops. There are some information posters here, and there is also an easily accessible footpath.

Here you can experience the wild coastal landscape of Eastern Norway, far from any hustle and bustle. The loop starts at the distinctive Kråkerøy church and leads over solid wooden bridges and smoothly polished Svaberg rocks out to the outermost islets of Glufsa. A name that is no coincidence: „Glufs* means «gust of wind» in Old Norse, and that is exactly what you feel here when the southwest wind meets the currents of the Oslo Fjord. Along the way, it is worth taking a look into the rock pools and gorges. An impressive Jettegryte awaits in a rocky bay. A giant's kettlehole formed by water as a silent testament to the forces of nature. The tour is accessible all year round and, thanks to its moderate altitude profile, is also suitable for families.
