Vava'u Group dive sites

Yes, Swallows Cave is very accessible. The cave opening is wide and well-lit, with a maximum depth of about 18 metres at the entrance that shallows to around 5 metres inside. There are no narrow passages or overhead restrictions that would trap a diver. Snorkellers can float at the surface and enjoy the light effects from above. Calm conditions during the dry season from May to November make this an ideal site for less experienced visitors.

The cave faces north-northwest, and during late morning the sun angle aligns perfectly with the cave mouth, sending beams of concentrated light through the turquoise water. The limestone walls and white sandy bottom reflect and amplify the light, creating an otherworldly blue glow. The effect is strongest between 10 am and noon on clear days, so most operators time their visits accordingly.

Absolutely. The whale swimming season in Vava'u runs from July to October, overlapping perfectly with the best conditions at Swallows Cave. Most operators offer half-day whale swim trips in the morning and can arrange a Swallows Cave visit in the afternoon, or vice versa. The cave is located on Kapa Island, only a short boat ride from the main whale swimming areas in the Vava'u channel system.
