With the weather getting more appealing for sun-seeking holidaymakers and backpackers, some of Tonga’s more remote islands with glorious resorts and eco-fales are a great option. Catch them during the quiet season before the tourist crowds arrive for the summer. The main hub of Tongatapu is also worth spending at least a few days checking out the Easter ceremonies in this nation of devout Christians.

Tongatapu – While the weather is still a little “iffy” causing some flight cancellations, April is a good time to explore Tonga’s main island, Tongatapu. Check out a church service around the Easter period to experience the singing of passionate locals. Visit Tongatapu’s most popular caves, blowholes, beaches and historical sites with virtually no other tourists around. Find out more about what to do in Tongatapu in The Complete Guide to Tongatapu.

Ha’apai – When the shops and services of Tonga’s main hubs are closed for four days over the Easter period, it’s a good time to escape to an idyllic island resort.
