Two days is Trinidad only, honestly. The ferry to Tobago runs 3 to 4 hours each way and the flight adds airport time on both ends, so a fair island split needs more time than this. Trinidad and Tobago runs on the TT dollar (TTD, roughly TT$6.8 to US$1), not the Eastern Caribbean dollar used next door, and this short trip sticks to Port of Spain and a Maracas Bay day trip over the Saddle Road.

Three days still stays on Trinidad, and that’s the honest call: the ferry to Tobago runs 3 to 4 hours and the flight adds transfer time on both ends, so a real island split wants more runway than a long weekend gives. This plan nests the 2-day route inside it and adds a third day built around Trinidad’s least beach-shaped attraction, a sunset flight of scarlet ibis over a mangrove swamp.

A full week is the first plan on this list where neither island feels shortchanged: three Trinidad days, a crossing day, then three Tobago days that finally reach past the reef into the rainforest and a beach with no entrance fee. This nests the 6-day route and adds a Day 7 finish. Prices run in TT dollars (TTD, roughly TT$6.8 to US$1), best in the dry season, January to May, or around Carnival (16-17 February 2026) if volume is the point.

Four days is the shortest trip that fairly earns a taste of both islands, and it’s still lopsided: three Trinidad days for doubles, Maracas, and the Caroni ibis, then a Day 4 crossing that lands you in Tobago with an afternoon, not a reef tour. This nests the 3-day plan and adds the hop across. Prices run in TT dollars (TTD, roughly TT$6.8 to US$1), best in the dry season, January to May.

Five days is where Tobago stops being a rushed afternoon and starts being an actual second leg of the trip. This plan nests the 4-day route (three Trinidad days, then the crossing) and adds a full Day 5 built around the reef most visitors fly here for. Prices run in TT dollars (TTD, roughly TT$6.8 to US$1), and the dry season, January to May, is the reliable weather window. Book these before you go

Six days lets Tobago stretch past the beach and into the hills. This plan nests the 5-day route (three Trinidad days, the crossing, a full Buccoo Reef day) and adds a Day 6 built around the oldest legally protected forest reserve in the Western Hemisphere. Prices run in TT dollars (TTD, roughly TT$6.8 to US$1), and renting a car for this one day genuinely earns its cost. Book these before you go
