Given that weather conditions are good, "snorkeling with seals tours" start from Hout Bay Harbour heading towards the seals colony at Duiker Island. The up to 8 passengers get an extensive briefing in the harbour before the boat trip to Duiker Island begins. The small, just 1,5 square kilometres big island, is locating one of the biggest south african colonies of seals and a special experience of nature. The immediate proximity to wilderness and the habitat of the seals is breathtaking. Provided with the appropriate equipment, snorkelers can stay up to 45 minutes under water and approach extremely close to the seals. Best time for this fascinating adventure is between December and March as the very curious baby seals are not shy to encounter the snorkelers.
