Angel waterfalls, Venezuela.

Angel Falls, the tallest waterfall in the world, drops nearly a kilometer (about 979m total drop with 807m freefall) from a table-top mountain (tepuy or tepui in the indigenous Pemón language). 

The waterfall has been known as the "Angel Falls" since the Mid-20th century; they are named after Jimmie Angel, a US aviator, who was the first person to fly over the falls. Angel's ashes were scattered over the falls on 2 July 1960.

Angel Falls is one of Venezuela's top tourist attractions, though a trip to the falls is a complicated affair. The falls are located in an isolated jungle. A flight from Puerto Ordaz or Ciudad Bolívar is required to reach Canaima camp, the starting point for river trips to the base of the falls. River trips generally take place from June to December, when the rivers are deep enough for use by the Pemon guides. During the dry season (December to March) there is less water seen than in the other months.

Glow worm cave, New Zealand

The Waitomo Glowworm Caves attraction is a cave at Waitomo on the North Island of New Zealand, known for its population of glowworms. This species is found exclusively in New Zealand. They are around the size of an average mosquito. This cave is part of the Waitomo Caves system that includes the Ruakuri Cave and the Aranui Cave.

The attraction has a modern visitor centre at the entrance, largely designed in wood. There are organized tours that include a boat ride under the glowworms.

The Waitomo Glowworm Caves are located in the southern Waikato region of the North Island of New Zealand, 12 km northwest of Te Kuiti. This cave is about 2 hours south of Auckland, 1 hour south of Hamilton, and 2 hours west of Rotorua by car. The directions to the Caves are to exit State Highway 3 onto Waitomo Caves Road and to continue on the road for about 8 km.

Glass Beach, California, USA

Glass Beach is a beach in Mac Kerricher State Park near Fort Bragg, California that is abundant in sea glass created from years of dumping garbage into an area of coastline near the northern part of the town.

The beach is now visited by tens of thousands of tourists yearly. Collecting is discouraged on the section of "Glass Beach" within and adjacent to the state park, although most of the sea glass is now found on the other two glass beaches outside the state park area.

About 1,000 to 1,200 tourists visit Fort Bragg's glass beaches each day in the summer. Most collect some glass. Because of this and also because of natural factors (wave action is constantly grinding down the glass), the glass is slowly diminishing. There is currently a movement by Captain J. H. (Cass) Forrington to replenish the beaches with discarded glass. On December 10, 2012, the City Council of the City of Fort Bragg, discussed the beach glass depletion and declined to move forward with replenishment efforts due to the cost and perceived likelihood that required permits would not be approved.

Similar beaches are found at Benicia, California and Hanapepe, Hawaii.
