The Limietberg Nature Reserve offers some of the best hiking trails in the Western Cape, and the Krom River trail in particular stands out, as it guides you past waterfalls and deep, translucent rock pools that are clear enough to snorkel in. The water is ice cold, but that will probably come as a relief after the long hike.
Note: Pets are not allowed in CapeNature Reserves.
You need a permit, which can be purchased at Du Kloof Trout Farm (just after the tunnel on your left) or from the CapeNature booking office. Only 24 permits are issued per day to prevent overcrowding, so plan ahead.
