You don't need a long-haul flight to trade Singapore's city buzz for sand and sea. Within a couple of hours, there's a surprising spread of islands to choose from, whether you want a laid-back day trip or a full weekend away.

The easiest escape is Pulau Ubin, the granite island whose quarries once supplied stone for landmarks like Horsburgh Lighthouse and the Causeway before the last quarry shut in 1999. Today those pits are water-filled scenery, best explored by bike on trails past kampong houses and mangroves. Rent a cycle near Ubin Village, tackle the 10km of routes at Ketam Mountain Bike Park, climb 74m Puaka Hill for quarry views, or wander Chek Jawa Wetlands, where six ecosystems meet and marine life shows best when tides drop below 0.5m. For deeper context, Wan's Ubin Journal runs a 2.5-hour Malay heritage walk with an Orang Pulau descendant ($100 including the bumboat fare). Overnight? Camping is free with an NParks permit applied for at least two weeks ahead. Getting there is half the charm: a 10-minute traditional bumboat from Changi Point Ferry Terminal, $4 each way, departing on demand from 6am to 7pm once 12 passengers gather. Note that part of Chek Jawa's Coastal Loop boardwalk closes from 15 September 2026 until April 2027.

If you'd rather stay in Singapore waters, Lazarus Island offers proper beach time at Eagle's Bay, plus a 15-minute causeway stroll to St John's Island and kayaking or paddleboarding at the sea sports centre. Ferries leave from Marina South Pier, with Singapore Island Cruise tickets from $15. Overnight options include five eco tiny houses at Tiny Away Escape (bookable until January 2027, before a scheduled February closure) and glamping with Into the Woods. Pack food and water, and check the last ferry back — but leave the passport at home.

For something more indulgent, Indonesia's Cempedak Island, about 9km off Bintan, is an adults-only (15+) private island resort with just 20 bamboo-and-granite villas, opened in 2017 by the team behind neighbouring Nikoi. Half the island is protected rainforest, and the surrounding East Bintan Marine Protected Area shelters hornbills, otters, turtles and the critically endangered Sunda pangolin. It suits a multi-night stay rather than a quick dash.

The full list also flags Sugi Island for overwater villas, snorkelling off Rawa, and Bintan and Batam for travellers willing to look past the usual resorts and shopping malls.

Why it matters: these islands cover every style of break — free camping, picnic beaches, and barefoot luxury — all reachable without an airport. Ubin and Lazarus work as same-day trips on a modest budget, while Cempedak is the pick for an anniversary or special weekend. Bring cash for the bumboats, wear covered shoes on Ubin's trails, and always double-check return ferry times.
