Is 7 days enough for Costa Rica?
Yes. Seven days is enough to combine Arenal, Monteverde and one beach destination like Manuel Antonio without feeling rushed, as long as you limit yourself to two or three bases.
What is the best 7-day Costa Rica route?
Arenal/La Fortuna (3 nights), Monteverde (1-2 nights), then Manuel Antonio (2 nights). Fly in and out of San José.
Should I rent a car or use transfers for a Costa Rica itinerary?
Private transfers or shared shuttles are easiest for this route since drives are long and signage is limited. A car adds flexibility if you're comfortable with rural roads.
