There is a moment in Aspen, somewhere around a quarter to four, when the mountain empties in a single rush. The last chairs are still turning, but boots are already clumping across the base area, and within twenty minutes the decks are full. Knowing where to go in that window — and where to go afterwards, when the sun drops behind Aspen Mountain and the temperature drops with it — is the difference between a pleasant afternoon and a memorable one.

Aspen has four mountains and, in practice, four different après scenes. What follows is a working guide to all of them: the mid-mountain decks, the base-area institutions, the town classics, and the live music that carries things on once the happy-hour prices end.

How an Aspen afternoon is structured

Aspen's lifts generally stop spinning around four o'clock, with the mid-mountain restaurants closing a little earlier and the decks staying busy well past six. The rhythm is predictable, and once you know it you can plan around the crowds rather than standing in them.

Mid-mountain first. If you want a drink at altitude, with the sun still on your face, you have to be there before the lifts close — there is no walking up afterwards. Then the base area, roughly four until six, when the decks are loud and standing room only. Then town, from six onwards, for something to eat. Dinner reservations anywhere popular are worth making in the morning, sometimes the day before.

• Altitude changes the maths. Aspen sits at roughly 2,400 metres, and one drink here can feel like two. Alternate with water and eat something salty before the second round.
• Layers matter more than outfits. A sunny deck at four becomes a cold deck by five-thirty. A down jacket over the base layer is normal, not overdressed.
• Boot bags are welcome. Most places have a rack, a corner or a cloakroom. Ask at the door rather than guessing.
• Cash and cards both work, and service is tipped in the American style — 18 to 20 per cent is the norm on a bar or restaurant bill.

On the mountain: the last-run detour

The best-value après in Aspen happens above the base, before the lifts stop. On Aspen Mountain, Bonnie's has long been the spot for a late lunch that slides into an early afternoon drink, with a sunny deck and a menu built for sharing. The Sundeck, at the top of the gondola, offers the widest view and the coldest beer-with-a-view combination on the mountain.

At Aspen Highlands, Cloud Nine Alpine Bistro is the well-known one — a small European-style chalet above the treeline where the rosé flows and the atmosphere gets loud. Tables there are limited and booked well ahead, and it is not the place for a quiet conversation. At Snowmass, the Elk Camp and mid-mountain cafeterias are the practical option for a last hot chocolate or a beer before the final run down.

At the base: the deck scene

Ajax Tavern, at the foot of the Silver Queen Gondola, is the classic Aspen base-area stop: a terrace that catches the afternoon sun, a menu of burgers and fries, and a crowd that arrives in ski boots and stays longer than planned. It fills fast on bluebird days, so either get there early or accept standing at the rail.

The terrace at The Little Nell next door is the smarter, quieter end of the same scene — better for a glass of wine and a proper sit-down than for a party. Both are a two-minute walk from the gondola, which makes them the easiest first stop if you have children in tow or a dinner booking to make.

In town: the classics

Aspen's town core is compact, walkable and denser with bars than its size suggests. A few places have earned their reputation over decades.

The J-Bar at the Hotel Jerome is the historic one — dark wood, a long bar, a good burger and a crowd that mixes locals, visitors and whoever is in town for the week. The Red Onion on Cooper Avenue bills itself as one of the oldest saloons in Colorado and delivers exactly what that suggests: cold beer, pub food and a lively room. Eric's Bar, tucked upstairs on Hyman Avenue, is smaller and more local in feel, the sort of place where you end up talking to the table beside you.

For something less saloon-like, Aspen Brewing's taproom pours beer made a few blocks away, and the handful of wine bars around the pedestrian mall do small plates and by-the-glass lists that work well if you have eaten properly at lunch.

Snowmass and Highlands

If you are staying down-valley, there is no need to drive into Aspen at all. Snowmass Mall has the most concentrated après in the village, with Zane's Tavern as the long-standing centre of gravity and Base Camp filling up as soon as the lifts close. At Aspen Highlands, the base-area alehouse is the obvious stop, with a fire, a decent burger and a short walk to the car park.

The free RFTA buses connect all four mountains and the town, and they run into the evening. It is a genuinely useful service rather than a token one — the run between Snowmass and Aspen takes around half an hour, and it saves arguing about who is driving.

Live music and the later hours

Aspen's live music scene runs from the informal to the ticketed. In the early evening, you will find solo guitarists and small trios in the base-area bars and along the mall — free, loud enough to enjoy, quiet enough to talk over.

For a proper gig, Belly Up Aspen is the main venue, with touring acts most weeks; doors are usually later in the evening, so check listings and buy ahead for anything well known. The Wheeler Opera House programmes music, comedy and film throughout the winter. Local listings in the free papers and on venue noticeboards are the fastest way to see what is on during your stay.

Cheap eats and the sober option

Not every après needs a table and a wine list. Aspen does quick food well: wraps and burritos from the long-standing takeaway counters near the mall, pizza by the slice, deli sandwiches made to order, and a bakery counter that has been selling cookies to tired skiers for years. These are the places to go if you want to eat at five o'clock, spend little and be asleep by nine.

Non-drinkers are well served too. Coffee shops stay open late, most bars will make a decent alcohol-free cocktail or pour a good soda and lime, and nobody blinks at a table ordering sparkling water. Drivers should note that American drink-driving rules are strict and enforcement is real.

Practical notes for a good après

• Check before you go. Aspen has quiet shoulder seasons, and individual venues change hands, hours and menus. A quick look at a venue's own site or a phone call saves a wasted walk.
• Book dinner early in the day, and if you want a specific deck table at four, arrive by half past three.
• Give yourself an hour. The gap between the lifts closing and dinner starting is where the good conversations happen.
• Go easy on the first drink. Altitude, dehydration and a day of exercise make alcohol hit harder. Headache, nausea or breathlessness that does not settle is worth taking seriously — speak to a doctor or the ski patrol rather than pushing on.
• Never ski or drive after drinking. Leave the boots at the base and walk into town; almost everything worth visiting is within fifteen minutes on foot.

Get the timing right and Aspen's après stops being a scramble for a seat and becomes the best hour of the day. Start on the mountain, work down to the base, finish in town, and let the buses do the rest.
