So you've decided to hike Machu Picchu? Well great! There's no doubt that you're in for the experience of a lifetime. However, the truth of the matter is that now you've got some additional decisions to make. You see, there's more than one route to arrive to the world-famous Inca site, and even once you've arrived there are a few choices to make as well.

But don't fret! If you're looking to hike Machu Picchu, we've got the information you need to start planning your trip.

Hike Machu Picchu: Arriving to the Site

1. Classic Inca Trail

The Classic Inca Trail is a four-day trek stretching some 42 kilometers along an ancient road built by the Incas themselves. This is undoubtedly the most famous route to Machu Picchu, and it's the one way that offers the opportunity to enter the city through its storied Sun Gate. Frankly, we've got tons of information on the Inca Trail on other pages of our site, so we won't waste too much space being redundant here. Check out these pages for more information on the trail's itinerary as well as for access to an Inca Trail map.

2. One-Day Inca Trail

Whether you're crunched for time or simply don't feel physically up to four full days of trekking, don't fret--a small taste of the world-famous Inca Trail is still available to you! A number of tour companies offer an abridged version of the trek, either one full day of hiking or a shortened day followed by a night of camping and a dawn arrival at Machu Picchu. Besides the Inca Trail's famed destination, the one-day version of the trek also takes you past Wiñay Wayna, another favorite ruins along the trail. The bad news here is that you'll still need to reserve one of only a few hundred daily Inca Trail passes, meaning that, just like the full Inca Trail, you'll need to book this trek months in advance.

3. Lares Trail

Just north of the world-famous Sacred Valley sits the comparatively lesser-known Lares Valley, and whereas the former can be swarmed with tourists especially during the high season, life in the Lares Valley continues humming along relatively unchanged. So whether you're looking for a simpler, more culturally-immersive experience or if you just didn't book an Inca Trail pass in time, the Lares Trail is an excellent option! Lucky for you, we've already gathered plenty of information on the Lares Trail including the trek's daily itinerary and a side-by-side comparison of the Lares and Inca Trails if you're struggling to decide how to hike Machu Picchu.

4. Vilcabamba Traverse Route

Warning--this option is neither for the faint of heart nor the out of shape! The Vilcabamba Traverse Route is one of the newest on the Peru trekking circuit, clocking in at nearly 100 kilometers over the course of a week of trekking. Though very difficult, the route is especially rewarding--think a variety of diverse biomes and the ruins of Choquequirao, often compared to Machu Picchu although less than 40% of the site has been excavated (pictured above). Though visited by only 5,000 or so brave trekkers last year, be warned--the local government is pushing a plan to build a cable car to the site! If you want to see the ruins in their current, undisturbed state, it would be best to go sooner than later.

Hike Machu Picchu: Once You're There

5. Huayna Picchu

Just because you've finally arrived at Machu Picchu doesn't mean your hiking experience has to end! The famous mountain soaring in the background of most iconic Machu Picchu photos is possible to hike, and the experience is certainly recommended. The views from the top are great, and on the way down you can even take a back route to the storied Temple of the Moon. For more information on Huayna Picchu, you can check out this past post on our site.

So that's it for today! If you're planning to hike Machu Picchu and have any questions you'd like to ask us, feel free to reach out in the comments section below. And, if you've already done one of these hikes, feel free to share your experience as well. We appreciate all of your comments!

Bacterial type VII secretion systems secrete a wide range of extracellular proteins that play important roles in bacterial viability and in interactions of pathogenic mycobacteria with their hosts. Mycobacterial type VII secretion systems consist of five subtypes, ESX-1–5, and have four substrate classes, namely, Esx, PE, PPE, and Esp proteins. At least some of these substrates are secreted as heterodimers. Each ESX system mediates the secretion of a specific set of Esx, PE, and PPE proteins, raising the question of how these substrates are recognized in a system-specific fashion. For the PE/PPE heterodimers, it has been shown that they interact with their cognate EspG chaperone and that this chaperone determines the designated secretion pathway. However, both structural and pulldown analyses have suggested that EspG cannot interact with the Esx proteins. Therefore, the determining factor for system specificity of the Esx proteins remains unknown. Here, we investigated the secretion specificity of the ESX-1 substrate pair EsxB_1/EsxA_1 in Mycobacterium marinum. Although this substrate pair was hardly secreted when homologously expressed, it was secreted when co-expressed together with the PE35/PPE68_1 pair, indicating that this pair could stimulate secretion of the EsxB_1/EsxA_1 pair. Surprisingly, co-expression of EsxB_1/EsxA_1 with a modified PE35/PPE68_1 version that carried the EspG5 chaperone-binding domain, previously shown to redirect this substrate pair to the ESX-5 system, also resulted in redirection and co-secretion of the Esx pair via ESX-5. Our results suggest a secretion model in which PE35/PPE68_1 determines the system-specific secretion of EsxB_1/EsxA_1.

Navigation often requires movement in three-dimensional (3D) space. Recent studies have postulated two different models for how head direction (HD) cells encode 3D space: the rotational plane hypothesis and the dual-axis model. To distinguish these models, we recorded HD cells in female rats while they traveled different routes along both horizontal and vertical surfaces from an elevated platform to the top of a cuboidal apparatus. We compared HD cell preferred firing directions (PFDs) in different planes and addressed the issue of whether HD cell firing is commutative—does the order of the animal's route affect the final outcome of the cell's PFD? Rats locomoted a direct or indirect route from the floor to the cube top via one, two, or three vertical walls. Whereas the rotational plane hypothesis accounted for PFD shifts when the animal traversed horizontal corners, the cell's PFD was better explained by the dual-axis model when the animal traversed vertical corners. Responses also followed the dual-axis model (1) under dark conditions, (2) for passive movement of the rat, (3) following apparatus rotation, (4) for movement around inside vertical corners, and (5) across a 45° outside vertical corner. The order in which the animal traversed the different planes did not affect the outcome of the cell's PFD, indicating that responses were commutative. HD cell peak firing rates were generally equivalent along each surface. These findings indicate that the animal's orientation with respect to gravity plays an important role in determining a cell's PFD, and that vestibular and proprioceptive cues drive these computations.

SIGNIFICANCE STATEMENT Navigating in a three-dimensional (3D) world is a complex task that requires one to maintain a proper sense of orientation relative to both local and global cues. Rodent head direction (HD) cells have been suggested to subserve this sense of orientation, but most HD cell studies have focused on navigation in 2D environments. We investigated the responses of HD cells as rats moved between multiple vertically and horizontally oriented planar surfaces, demonstrating that HD cells align their directional representations to both local (current plane of locomotion) and global (gravity) cues across several experimental conditions, including darkness and passive movement. These findings offer critical insights into the processing of 3D space in the mammalian brain.

A number of studies have demonstrated community acceptance of Safe Routes to School interventions as well as their success in addressing perceptions about safety, but little is known about their effectiveness in reducing pedestrian injury risk in school-aged children.

Implementation of a Safe Routes to School program in New York City may have contributed to a substantial reduction in school-aged pedestrian injury rates, with the effects largely limited to school-travel hours in census tracts with these interventions. (Read the full article)
