Zamkovského Chata is your recommended stopover between stage 2 and 3. This is a long day’s walk: you should allow 6.5 to 7 hours all told.
Head back up through the woods from the chata on the green path to where you turned off from the red route. On the Tatranská Magistrala, in red as ever it was, it’s around 50 minutes on an easy-going path to Hrebienok, where you can take the chairlift down to Starý Smokovec (the main resort village in the High Tatras; see how Hrebienok and Starý Smokovec link up with the Tatras Mountain Railway here). Easy-going in gradient, that is, and easy-going in terms of the signposting, but damnably rocky, meaning you are watching your footing every single step. First off you head downhill, twisting passed a quite impressive waterfall:
Down and over a river and it’s the forest track heading uphill that you want; this climbs to a noticeboard then heads straight on (it’s even paved in places) heading slightly down overall to get to Hrebienok.
Here the path skitters round the Hrebienok outbuildings (there’s a chata here, Biliková Chata, where you can stay) then cuts uphill through forest which took a beating in the spring storms this year towards Sliezsky Dom. Allow 2 hours to reach Sliezsky Dom from this point.
Many of the red waymarks on this stretch are missing because the trees they were painted on have fallen. The path climbs relentlessly however, twisting up through forest that is soon thick again, and climbs some 400 metres. It comes out into wilder moorland where views down to Starý Smokovec are pretty good, and there, at the end of a long forest road and perched at the edge of Velicke Pleso, is Sliezsky Dom. It’s possible to stay at this vastly overpriced eyesore of a hotel, but for hikers who have experienced the friendliness of mountain houses like Chata Pri Zelenom Plese, Zamkovského Chata or (for those hiking the path in reverse) Horský Hotel Popradské Pleso, this one is a shocker: an arrogantly staffed, dismal communist-built colossus with rooms a-plenty and unsurprisingly few takers for them. It’s dingy and actually not even completed, which makes one wonder how they can charge the prices they do. It is strongly recommended to stay at (ideally) Zamkovského Chata, Biliková Chata or Horský Hotel Popradské Pleso rather than here. Even the bar/restaurant was a Godforsaken place: I was happier to munch my dried fruit down by the lake in the drizzle. Anyway. You have been warned. The view from here, however, is beautiful, with a couple of waterfalls a short hike away:
The path from here continues up around the back of the hotel and from here it’s still a tough 3.5 hour hike to Horský Hotel Popradské Pleso. You’re very soon up in wild moorland here, and back up above the snowline for large stretches. In its bleakness, however, this stretch of the path is beautiful and otherworldly: just leave enough time to enjoy it and if you’re running out of light or if the weather is bad DO NOT attempt the final descent down to Horský Hotel Popradské Pleso. There is a bad weather option in addition, as detailed below.
The trail, marching along a specially constructed path of boulders, as it has at various points thus far, meets a yellow trail coming up from the access road to Sliezsky Dom after 30 minutes of hiking. After the junction, the path ascends very steeply into perhaps the most daunting landscape of the entire hike: the icy locale of Batizovské Pleso, where the water gleams an ethereal ice-blue and the boulder-strewn surrounds are like a little snapshot of Siberia, juxtaposed onto the High Tatras. The route coasts up the right side of a vast U-shaped valley, with Batizovské Pleso at the top, hugs the contour as it negotiates the southern lakeshore and then arrives at a junction where, as stated before, you need to make a choice.
From the junction of the red Tatranská Magistrala and the yellow trail (the one that goes down) it’s 2 to 2.5 hours onto Horský Hotel Popradské Pleso on the red route or 1 hour 45 minutes down to the tiny village of Vyšné Hágy on yellow.
Good Weather Option
Of course, in an ideal world you would follow the red Tatranská Magistrala on to your stage 3 destination from here. The path is fine (although it does climb up to nigh on 2000 metres, so another 100 metres up from Batizovské Pleso) BUT then comes the demanding descent a good 600 metres straight down to the lake of Popradské Pleso. The official trail guide makes little of this descent and says it’s doable in 45 minutes. That may be true, but for those not used to the legendary Tatras chain descents (i.e. where you absolutely have to cling to a chain or you will fall in places) this is a formidable and vertigo-inducing path. Do not attempt the red route from this point onto Popradské Pleso unless you have at the least 2.5 hours of daylight left – and even then not from October to May when snow obscures parts of the descent.
Bad Weather Option
The alternative is in any case quite pleasant: an easy, although again extremely rocky, path down into pine forest (it follows a river for a while which is intense in spring and winter) to Vyšné Hágy which has no accommodation but does boast a sports pub and a stop on the High Tatras mountain railway between Poprad/Starý Smokovec and Popradské Pleso/Štrbské Pleso. Keep to the red trails through the forests, descend to a farm where an inordinate amount of tractors seem to park, then cross the mountain railway line and bear left to ascend again slightly to the station. It’s then one stop on the line to the isolated Popradské Pleso station and the much-easier one hour hike back up to Popradské Pleso and Horský Hotel Popradské Pleso (on a blue trail).
When you get to Popradské Pleso there are actually two accommodation options right next to each other on the western shore where the road ends: Horský Hotel Popradské Pleso and another chata right next to it, which is by all accounts very nice too. It’s time for a plate of dumplings and possibly more than one beer: you’ve arrived.
