2 . The Best Caves in The World

Hang Son Doong, Vietnam

Natural caves don’t come much larger than Hang Son Doong, close to the border between Laos and Vietnam. This cave possesses the largest cross-section of any known cave on the planet, a vast area that is difficult to describe. Supposedly, a Boeing 747 could fly through without damaging its wings, but that doesn’t really do justice to the vastness of Hang Son Doong. The stalactites (钟乳石) here are pretty massive too, with some reaching up to 80 metres.

Waitomo Caves, New Zealand

Glowworms (萤火虫) are there, as far as the eye can see. Okay, not literally, but the Waitomo Cave system on New Zealand’s North Island is best-known for the fluorescent fauna that light up the walls, giving it the not-particularly-creative but completely acceptable “Glowworm Caves” nickname. They are more accessible than other caves on this list, with rafting and adventure tours available to those looking for something a little more thrilling.

Mammoth Cave, the USA

If you have certain expectations from somewhere called “Mammoth Cave”, that is entirely understandable. Mammoth Cave in Kentucky is the world’s longest known cave system, an incredible 420 miles of underground wonder. That’s twice as long as the next longest, by the way, although it isn’t unusual for the USA to go all out on such things.

Reed Flute (芦笛) Cave, China

Named after the reeds that grow outside, which are used to make flutes, obviously, the Reed Flute Cave’s walls are covered with inscriptions from centuries gone by—if evidence was needed that people have been paying attention to this place for a long old time. The inside part of the cave is also lit up by multicoloured lights, giving it a real otherworldly theme that adds weight to the nickname.

5 . Here are some fantastic parks in San Antonio.

Brackenridge Park

The park was first established in 1899 and has been popular with both locals and visitors ever since. Towering trees and peaceful riverbanks will greet guests along the park’s paths, and the facilities include playgrounds, museums, a miniature train, a Japanese tea garden, and one of the oldest golf courses in the city.

Friedrich Wilderness Park

In the park, you’ll find about 10 miles of paved(铺过的)and unpaved trails(路线), with a little something for everyone. From rocky climbs to deep canyons, and enchanting forests to open views, there’s no shortage of natural beauty. The area is nationally famous for birdwatching.

San Antonio Missions National Historical Park

The park is the state’s only one on the list of UNESCO World Heritage Site. It covers quite a large area, so it’s best to make it a full-day or at least a half-day trip so you can be sure to cover everything. While the Alamo is a separate attraction, you will get to enjoy the architectural wonders of Mission Concepcion, Mission San Jose, Mission San Juan, and Mission Espada. They’re all connected by a hike and bike trail, with plenty of stops along the way to picnic, climb trees, and refill water. Admission is free!

Eisenhower Park

Just a 20-to 30-minute drive from the city center, the park puts the best landscapes in the Texas Hill Country on full display, holding 6 miles of hiking trails, both paved and unpaved.

7 . National parks are an excellent way to explore all the beauty that the world has to offer: whether it’s endangered species, erupting volcanoes and snowy mountains, or rainforests and lakes. Of the thousands of national parks that exist in the world, these are the ones that should be on everyone’s bucket list.

Yorkshire Dales, United Kingdom

Contrary (相反) to the popular link of national parks with the wilderness, it is filled with winding valleys, hills and villages where over 24,000 people live and work. Visitors can walk through grassland, visit waterfalls or explore underground caves, but Yorkshire Dales is also home to several food shops, and the park hosts cheese festivals and farmers markets regularly, so it’s best to go hungry.

Kakadu National Park, Australia

It is a delight for those who like a bit of history mixed with the biodiversity of national parks. While it houses thousands of species of wildlife, there’s more to the national park than that.

Guilin and Lijiang River National Park, China

It is surrounded by striking natural beauty and can be explored by land. But the river national park, as the name suggests, is best explored through leisurely boat rides that take visitors through many ancient towns that come along the way of the river.

Vatnajökull National Park, Iceland

Here’s a surprising fact: The whole of Vatnajökull National Park makes up 14% of Iceland’s territory! The park is usually open for hikes around the glaciers; boat rides through glacier lakes, and tours that take visitors through the park’s many ice caves, waterfalls, and icebergs. Vatnajökull is also where two of Iceland’s most active volcanoes are located.
