Undiscovered places: readers' tips, recommendations and travel advice Australia Thirteen years ago, I spent a day on a boat out of Cairns navigating the edge of the Great Barrier Reef. I did some snorkelling with a marine biologist. I was hooked. Back in the UK I determined to sign up for scuba diving classes, in readiness for my return. But, somewhere along the line, "life" got in the way. I yearn to return and explore the Queensland coastline. I want to sail on a yacht around the Whitsundays, stopping off on white sandy beaches to make campfires like a real Swallow or Amazon. I want to plunge into blue waters, and discover the kaleidoscope of colours, and all that hidden life that exists beneath the ocean. I want to cuddle my very own sea cucumber. Sally Golanski, Surrey Tanzania I would like to discover the great wildebeest migration. Nowhere in the world is there a movement of animals as immense as the wildebeest migration, when more than two million animals migrate from the Serengeti National Park in Tanzania to the greener pastures in Kenya. I would love to follow and document them, taking pictures. Lee Dilley, by email Norway While chasing the Northern Lights, we took the coastal Hurtigruten ferry northwards ending up at Kirkenes in the far north of Norway. It really feels like an alien world - cold, dark and seemingly always snowing. Sadly, we only had time to transfer to our flight home so we would like to be able to spend a few days in this town well within the Arctic Circle. What would we do? Visit the nearby Russian border for an Alistair Maclean-type experience; make a day trip to the Ice Hotel by dog sled, meet and interact with the hardy Sami people who inhabit this lonely landscape all their lives. Oh... and, hopefully, see the Northern Lights - at last - in all their glory. David Reeves, Wiltshire Greece I had a brief visit to Ithaca, and would love to see more of the island. As well as the usual delights of a Greek island - warm sunshine, deep blue seas, relaxed lives and enjoyable meals, I felt the history of Greece, all the way back to Homer, was living around me. Ancient buildings and trees lived in harmony with modern times, and invited me to join in that harmonious co-existence. Stephanie Whitehouse, Norfolk The Balkans The area I would like to explore more extensively is the Balkans. I have briefly visited some hot spots in Croatia, Montenegro and Bosnia and the region is nothing short of stunning. Bright green rivers, ancient architecture, mottled with a troubled past and rich history make this region beautiful and exciting. It is still quiet, real and unspoilt by tourism. The nature is spectacular. I would love to take in the region extensively, visit the national parks, canoe along the rivers and absorb the wonderful culture. Melissa Ritchie, London I have had a long fascination with the ancient world, the politics, culture, learning and societal mores. I would like to see first hand some of the places where events took place, see the monuments and feel their presence. I wish to learn more about them in the museums and see how contemporary culture is and is not different from those days. I think it is important to learn from the past and how it affects the present and future and that a trip to Rome would provide a good deal of that. A M Taylor-James, London Russia-China For one of the most fascinating train journeys in the world, take a ride on the Trans-Siberian Railway, the longest in the world, connecting Moscow with the Russian far east and the Sea of Japan (or Beijing should you opt for the Trans-Mongolian route). You should begin your adventure in Moscow, which has a rich history and some of the finest architecture in the world, including the Kremlin, Seven Sisters buildings and the Metro. Move onward through the vastness of Siberia before settling in Irkutsk, near Lake Baikal, the largest freshwater source on the planet. If heading south, Mongolia awaits. Spend time in a traditional Mongolian ger and live like a nomad before continuining on to colourful Beijing Imran Khan, London Japan The country I would most like to explore would be Japan. My husband and I have been to the island of Honshu and seen the popular tourist sites, including Tokyo, Kyoto, Himeji castle, Nikko, Nara, Hiroshima and the island of Miyajima. The people are not just exceptionally polite, but very helpful and extremely hard-working. The other islands appeal too, especially Hokkaido, where I believe the skiing is wonderful and they have a winter display of ice sculptures; Shikoku for the Teshima art museum, Ritsurin garden, the Kochi botanical gardens, the observatory park and the shrines and temples; and Kyushu, for Shiratani cloud water valley. A visit to the spectacular beaches of the island would finish off the holiday perfectly. Maryclare Shields, Cheshire Fiji I would love to go to the islands of Fiji. My dream is to go island hopping from Port Denarau all the way through to the Nacula island. I want to sleep in a hut on the beach, no television, no radio and no internet, just the beautiful view of the blue seas and blue skies. I want to sleep under the stars and say hello to the hidden world in the sea. I want to feel as though I'm lost on a desert island and I have no wish to be found. Fiji is my dream holiday. Caroline O'Mullan, Kent United States I'd love to explore San Francisco as it was the city in which my late mother was raised. She'd often talk with passion about what the area had to offer and it's something I have longed to experience myself. I'd visit the markets of Fisherman's Wharf and take in the eerie history of Alcatraz while darting to see the Golden Gate Bridge on a cable car. I'd be hoping the magic of the Bay Area would not only give me an insight into what made my mum the person she became, but also help me be the person I want to be. Neil Renton, Edinburgh Canada I spent one night in the Hearst Lodge in the Fundy National Park, New Brunswick, Canada. It was on the Big Salmon River, and one night wasn't enough to take in the stunning scenery of this magnificent trail. New Brunswick is one of the lesser known provinces of Canada, but with its easy-going lifestyle you will be blown away with views from the lookout points on the trail. Not far away from here is Hopewell Rocks where at high tide there are some of the highest tides in the world, and just hours later at low tide you can stand on the bed of the Atlantic Ocean. The best time to go is before late September when the weather turns, but I guarantee you will not be disappointed with this untapped gem of a destination.
