Providenciales is filled with good snorkelling spots, but the best ones are arguably Bight Reef and Smith's Reef, both located in the central region of the island. You have good chances of spotting green turtles, southern brown stingrays and even nurse sharks. If you want to see nocturnal sea creatures like squid and octopus, you're free to do some night snorkelling (provided that you have the equipment for it).

For nature lovers, Christmas Island National Park provides fantastic opportunities to observe unique plants and animals in their natural habitats. The park covers about two thirds of the island. As an isolated oceanic island, distant from other land masses, Christmas Island is home to a high proportion of endemic species. Several are endangered. The park protects significant ecosystems including much of the island's uniquely structured rainforests and two wetlands of international importance, the Dales and Hosnie's Springs. In and around the national park you will find a host of native sea and forest birds, unique marine life and land crabs — including tens of millions of red crabs, famous throughout the world for their spectacular annual breeding migration.

Golden Sands is famous for its stunning golden sand and expansive beaches along the Black Sea. It's located 18 kilometres north of Varna, close to Golden Sands National Park. The resort boasts several kilometres of beachfront. The southern end is the more recently developed and less crowded, while the northern end features numerous bars and small shops. You can reach Golden Sands by public transport. Bus number 109 connects Varna city centre to the resort, although the journey typically takes a little over an hour. Taxis are also available, but they tend to be on the pricier side.

Varna's Sea Garden, stretching along the coast, is a beautiful public park that blends nature with seaside charm. This vast green space offers both relaxation and recreation, with shaded pathways, open lawns, and direct access to the beach. During the summer, you can swim in the Black Sea or browse stalls selling local souvenirs and handmade jewellery. The park is open year-round and it's free of charge.
