Northern Europe

Northern Europe groups 4 cities across 4 countries that share enough on logistics, weather pattern and currency exposure to budget as one block. The top-to-bottom ratio inside the region is 1.4× — Reykjavik runs about 1.4× the daily cost of Helsinki at the same mid-range tier — which is a usefully concrete way to think about where in the region to anchor a multi-stop itinerary.

Northern Europe has 4+ currencies in active use (DKK, EUR, ISK, SEK, …). Assume an FX event at every border, lean on cards in cities, and only convert what you need for the next leg.

A typical 10–14 day trip across Northern Europe works well as two or three anchors — e.g., Helsinki for slower, longer days and Reykjavik for one denser city stop — connected by the cheapest regional links you can find. Daily totals shift between anchors by up to 148 USD, so where you sleep matters more than how many activities you book. The single most common Northern Europe budgeting mistake is averaging the cities together: a 50/50 split between Helsinki and Reykjavik doesn't cost the average — it costs whatever you actually spend in each, weighted by nights. Build the budget per-anchor, then sum.
