Anyone who has nervously powerwalked to a welcome meeting knowing they're about to spend five days with eleven strangers will recognise this scenario. A writer on Intrepid's Golden Circle in Depth trip found that the emotional rollercoaster of group travel maps almost perfectly onto psychologist Bruce Tuckman's five-stage model of group development: forming, storming, norming, performing and adjourning.
Day one is all polite energy. The group shares a first dinner in Reykjavik, guided by trip leader Bjorn on what to order and how to say thank you in Icelandic, everyone smiling hard and sussing each other out. That's classic forming: best behaviour, unified by a common goal.
The wobble came on day two, driving past the lava-scarred outskirts of Grindavik, a town evacuated after eruptions between 2023 and 2025. Conversation felt stilted, bigger personalities dominated, and the writer spent the morning inexplicably irritable. This is the storming stage, when people jostle unconsciously for position in the group hierarchy. Knowing it's a normal phase, not a sign the trip is doomed, is the whole point of the theory.
By the geysir Strokkur and Gullfoss waterfall, things eased into norming: quirks became familiar, friction faded, and quieter group members opened up on a side hike to a viewpoint. Then came performing, in style, at the Secret Lagoon, a relaxed alternative to the busy Blue Lagoon, where communal nudity in the showers is simply Icelandic custom. Cold plunges, duty-free beers under the midnight sun and friendly teasing sealed the deal. The final stage, adjourning, hit hardest: a goodbye back in Reykjavik with hugs, open invitations to homes from Upstate New York to New Zealand, and a group chat to keep it alive.
Why should a traveller care? Because if you've avoided small-group tours for fear of awkward dynamics, this is reassurance that the discomfort is temporary and predictable. The nerves at the welcome meeting, the day-two grump, the in-jokes by night three — it's a process, and it works. And the writer's honest takeaway is that the strangers ended up being an integral part of the experience, not just a vehicle for seeing Iceland. If you're considering a small-group adventure anywhere, expect the arc and ride it out.
