The secluded beach behind the remarkable cave tunnel is only accessible sharp at low tide.
Tide times Port Arthur
Tasman National Park and also the Remarkable Cave close to Port Arthur are very popular. It’s a short trail, easily accessible, therefore, can be a bit crowded. Best visited early morning or evening at low tide. In summer, even tour buses arrive. Limited parking spaces.
The 3-4 hours return hike of about 9 km to Mount Brown starts here and passes the Maingon Blowhole. The blowhole itself is a 45 minutes return hike which makes sense at high tide only.
We recommend staying here at least three nights. If you are into hiking, don't miss the incredible Cape Raoul day hike which is 14 km long.
We'd chosen the affordable Port Arthur Holiday Park one of the Safari tents in an excellent location in the Stewarts Bay State Reserve. Each day we had parrots next to our tent. The wildlife and bird watching was an extra plus. It was just a 15 minutes drive to the cave. The reason that we visited the cave twice.
The dry season from April to October is the best time for a travel to the north. Better access at dry months. Usually, it's very hot at midday. Avoid the rainy season from December to March. Tropical storms can occur and it is even hotter.
Tours are being offered from April to October. The best chance for good weather conditions is during spring (April-June) and in September. There is a much higher chance to come ashore with pleasant weather and a calm sea. Therefore check the weather forecast before you book a tour. The chances for rain are higher in July and August.
The cave's face is southeast, therefore, best seen in the morning.
Inside of the famous Benagil Cave is a beach which is much bigger at low tide. Swimming into the cave can be quite challenging especially during rough seas! Swimm with a board and in a group not alone. Check the tides first before swimming! Anyhow, you need to be an experienced swimmer. An alternative is a boat trip to the existing caves at the Algarve.
Avoiding Crowds and Best Time for Swimming
Best months for swimming are June to September with pleasant sea temp. July and August are the peak season; Prices increase and beaches are pretty crowded. The Portuguese school holidays start mid-June and last roughly until the first week in September depending on the school. Therefore, the ideally times with fewer tourists and pleasant weather are the first half of June and at the beginning of September but even October is an excellent month. Bring a neoprene shorty for longer swimming though the sea temperature is around 21°C / 70°F during summer until October and 20°C / 68°F in June.
