Tucked away in the remote Mjóifjörður fjord, you'll find the magnificent Klifbrekku waterfalls, a true local secret. It's not just one waterfall, but a breathtaking series of seven cascades tumbling down the mountainside. Once you park on the roadside pullouts, there isn't an official trail, but you can follow a faint path for a short, steep climb to get closer to the lower tiers.
