Is there any possible way Las Vegas could not be on our "best nightlife" list? The only way we could possibly omit it is on a technicality—since you can do pretty much anything 24/7 in Vegas, it might be wrong to call it "nightlife."

The first time you go to New York, go ahead and be a sight-seer—everyone should visit the Statue of Liberty, the Met, Times Square, etc. But on a return trip, pick a neighbourhood and go deep. You’ll find hole-in-the-wall bars, great delis, quirky shops… exploring the non-touristy side of New York is an incredibly rewarding experience for a traveller.

Looking for a tropical Mexican fishing village with relaxing beaches, oceanfront seafood bars and restaurants, unspoiled reefs for diving and snorkelling, and waves suitable for championship surfing? Puerto Escondido has all that plus the Laguna de Manialtepec mangrove lagoon for tours combining kayaking, boating, bird-watching, and swimming in phosphorescent waters. Regularly scheduled airline service links Mexico City and Oaxaca to Puerto Escondido Airport (PXM). Rent an umbrella at the town beach, Playa Principal, which parallels the Avenida Perez Gasga hotel and restaurant row. Stop in one of the hotels near the beach for a drink or take the family horseback riding. A small freshwater lagoon at the mouth of the river, Rio Rigadillo, marks the border with Playa Marinero, which has waves suitable for beginning surfers. The whole family will enjoy the mile-long shoreline walkway known as Andador Escénico, which leads across the rocks to El Faro lighthouse and the Sueño Posible scenic overlook. Beyond the lighthouse, Playa Principal transitions into Playa Manzanillo, a swimmable beach with clear waters extending towards Puerto Angelito. Rent a boogie board or equipment to snorkel the coral and rocks. If Playa Manzanillo gets too crowded on a holiday weekend, catch one of the water taxis linking Puerto Escondido’s seven beaches. Hire a skiff to take the family sightseeing or dolphin and sea turtle viewing. Fish for trophy sailfish or catch a dinner of yellowfin tuna, mahi mahi (dorado), grouper, roosterfish, mackerel, or snapper. Watch the experts surf the 6-15 foot swells and hollow tubes of Playa Zicatela. International competitions in August and November draw the pros to demonstrate their prowess on the Mexican Pipeline. Snorkel or surf the clear shallow waters beneath the high cliffs surrounding Playa Carrizalillo. High red cliffs, housing, and hotels surround riptide-plagued Playa Bacocho, which is good for long romantic beach walks and sunsets. For more adventure, dive Pressure Point’s tectonic plate fault lines or Punta Colarada’s volcanic overhangs, ledges, and lava rock swimthroughs. If you are lucky you will see lobsters, stingrays, moray and snowflake eels, barracudas, yellow tangs, parrotfish, and puffers.

The main town of County Meath, Navan is the gateway to “the Heritage Capital of Ireland.” Ancient historic sites and religious ruins abound, and the Iron-Age monuments of the Hill of Tara alone are enough to fill you with awe. There’s so much more, though, like Trim Castle and the Abbey of Kells and the Neolithic standing stones of Brú na Bóinne. Book a guided tour so you can soak up as much as you can.

From Shoreditch’s swaggering style to Camden’s punky vibe and chic Portobello Road, London is many worlds in one. The city’s energy means that no two days are the same. Explore royal or historic sites, tick off landmarks from your bucket list, eat and drink in exclusive Michelin-starred restaurants, enjoy a pint in a traditional pub, or get lost down winding cobbled streets and see what you stumble across – when it comes to London, the possibilities are endless.
