Somasila is a wide, quiet reservoir on the Penna (Pennar) river in Nellore district, Andhra Pradesh, held back by an earth-fill and gravity dam below the eastern edge of the Nallamala hills. If you want a low-key day out among water and low hills within reach of Nellore city, Somasila rewards an unhurried visit rather than a packed sightseeing list.
Somasila is a large reservoir on the Penna river near Somasila village in Ananthasagaram mandal, Nellore district, Andhra Pradesh. It centres on the Somasila Dam, described by the district administration as the largest irrigation project in the district, with a riverside Someswara Swamy temple close to the water below the Eastern Ghats.

About Somasila and quick facts
Somasila is first and foremost a working irrigation reservoir, not a built-up resort town. The Somasila Dam stands across the Penna river near Somasila village in Ananthasagaram mandal, Nellore district, and the district administration calls it one of the biggest irrigation projects in the district.
A quick disambiguation first, because it trips up a lot of trip planning. There are two well-known Somasilas. This guide covers the Nellore one on the Penna river. The other Somasila is in Nagarkurnool district, Telangana, on the Krishna river in the Srisailam backwaters, and most of the pontoon-cruise and boating material online refers to that Telangana site, not this one.
On the engineering, the Andhra Pradesh Water Resources Department lists the Somasila project’s full reservoir capacity as 78.00 TMC at a full reservoir level of +100.58 m (+330 ft), fed partly by gravity water brought from the Srisailam reservoir in the Krishna basin. Wikipedia’s dam article gives the reservoir a surface area of 212.28 km2 (52,456 acres) and dates construction from 1985, with the dam opening in 1989; it records the dam as 39 m (128 ft) high and 760 m (2,493 ft) long, of earth-fill and gravity type with an ogee spillway, at 14 degrees 29 minutes N, 79 degrees 18 minutes E. Treat the finer engineering figures as reference rather than visitor-facing detail.

Best time to visit Somasila
The comfortable window to visit Somasila is roughly late November to February, when the heat has eased and the reservoir is usually full after the northeast monsoon. Incredible India rates October to March as the pleasant season for Nellore; the catch is that October and November carry the heaviest rain.
Nellore’s climate is tropical and the coast keeps humidity high. Incredible India’s monthly ranges show May running from about 19.8 C to 42.1 C, so March to June is hot and best avoided for a daytime trip to an exposed reservoir. According to climate-data.org, rainfall peaks in October at an average of about 194 mm, driven by the northeast monsoon, while March is the driest month.
| Season | Months | What to expect |
|---|---|---|
| Winter | Late Nov to Feb | Best time; cooler mornings, reservoir usually full, roughly 20 to 30 C |
| Summer | Mar to Jun | Hot and humid; May can touch about 42 C (Incredible India). Avoid midday |
| Southwest monsoon | Jul to Sep | Intermittent rain; greener hills; check road and gate-discharge news |
| Northeast monsoon | Oct to early Nov | Peak rainfall (about 194 mm in October); dam may release water |
How to reach Somasila
The practical gateway to Somasila is Nellore city, about 80 km away by road (an indicative planning estimate; Wikipedia’s dam article puts the dam roughly 79 km from the district headquarters). From Nellore you drive west towards Ananthasagaram; there is no direct rail or air link to the dam itself.
By air: The district administration lists Tirupati Airport as the nearest at about 120 km, with Chennai Airport about 190 km away. Tirupati has limited connectivity, so Chennai is often the more reliable arrival point for longer flights.
By rail: Nellore railway station (station code NLR) is the nearest railhead. The district site notes it lies on the Vijayawada to Gudur section, part of the Howrah to Chennai and Delhi to Chennai main lines, with a large number of trains halting daily. If you are building a wider state trip, Nellore connects easily by rail to Vijayawada on the Krishna.
By road: Nellore sits on the Chennai to Kolkata national highway, with state and private buses from Chennai, Tirupati, Hyderabad and Bengaluru. From Nellore, the last stretch to Somasila is best covered by hired car or taxi, as public transport to the dam is sparse.
| From Nellore to | Distance |
|---|---|
| Somasila Dam | About 80 km (indicative) |
| Tirupati | 130 km |
| Chennai | 172 km |
| Vijayawada | 224 km |
| Bengaluru | 377 km |
| Hyderabad | 516 km |
Things to see and do at Somasila
The main draw at Somasila is the broad sheet of water against low hills, best seen on a clear winter morning. The district’s places-of-interest page describes the setting simply: a major dam across the Pennar near Somasila village, with a Someswara temple and an ashram nearby, in the Eastern Ghats.
The Sri Someswara Swamy temple is the cultural anchor. It is a Shiva shrine by the river; according to the Deccan Chronicle, local legend dates it to the 12th century. In 2021, flood-management releases of nearly 5 lakh cusecs overtopped the temple’s protective wall, damaging sub-shrines, the Kalyana Mandapam (wedding hall), the Rajagopuram (gateway tower) and the compound wall, though the main sanctum stayed intact. The paper reports a reconstruction costing ₹13.50 crore through the Common Good Fund, with Bhoomipuja (ground-breaking ritual) held on 16 November 2024 and work expected to finish around February 2027. Check locally whether the temple is open before you plan around it.
On boating, be careful. I could not verify any officially listed boat operator at the Nellore reservoir, and the organised pontoon cruises widely described online belong to the other Somasila in Telangana’s Nagarkurnool district. Treat any Nellore boat ride as informal and weather-dependent, and ask the Somasila Project office or local staff on the day rather than booking in advance.
| Spot or activity | What it is | Time needed |
|---|---|---|
| Reservoir and dam view | Wide Penna reservoir against low hills; photography, quiet time | 1 to 2 hours |
| Sri Someswara Swamy temple | Riverside Shiva shrine, under reconstruction after 2021 floods | 30 to 45 min |
| Ashram near the temple | Quiet riverside spot noted by the district site | 20 to 30 min |
| Picnic by the water | Informal; carry your own food and water, pack out litter | Flexible |
A suggested short itinerary
Somasila works best as a half-day to full-day trip from Nellore, ideally paired with a temple stop or a second site so the drive earns its keep.
- Early start from Nellore: Leave by around 6 am to 7 am to reach Somasila before the day heats up and the light is good on the water.
- Morning at the reservoir: Spend an hour or two at the dam view and the Someswara temple area; keep expectations modest if the temple is still under repair.
- Midday: Carry a packed lunch, as reliable eateries at the dam are scarce; eat by the water and head back before the afternoon sun.
- On the way back: Stop at Jonnawada’s Kamakshi temple (about 12 km from Nellore) to round off the day near the city.
If you have a second day, combine Somasila with Udayagiri Fort or Penchalakona (see nearby places), both of which are longer, more demanding outings in their own right.
Where to stay near Somasila
There is no established tourist accommodation at the dam itself, so most visitors base themselves in Nellore city and make Somasila a day trip. Nellore has the usual spread of budget lodges, mid-range business hotels and a few higher-end properties near the bus stand and highway.
The bands below are indicative planning estimates for Nellore city and should be reconfirmed at the time of booking; they are not quoted from an official tariff.
- Budget (indicative, reconfirm): around ₹800 to ₹1,500 a night for simple lodges and guesthouses.
- Mid-range (indicative, reconfirm): around ₹1,800 to ₹3,500 for business hotels with air-conditioning.
- Higher-end (indicative, reconfirm): roughly ₹4,000 and up for the better-rated hotels in the city.
Book ahead during festival dates and the cooler November-to-February window, when demand around Nellore rises. If you want to be closer to the hills for a dawn start, confirm any local guesthouse near Ananthasagaram directly, as listings are thin and change often.
Food to try around Nellore
Somasila has little by way of restaurants, so plan your eating around Nellore, a town with a strong reputation for spicy, fish-forward coastal Andhra cooking. Carry water and snacks for the dam itself.
- Nellore chepala pulusu (tangy tamarind fish curry) is the dish the town is best known for; it is hot and sour, usually eaten with rice.
- Royyala iguru (dry-style prawn curry) and other prawn preparations are common, reflecting the coastal catch.
- Andhra meals (rice thali with rasam, sambar, curries and plenty of chilli and pickle) are the default vegetarian option.
- Filter coffee and tiffin such as idli, dosa and vada are easy breakfast choices before an early drive.
If you are travelling with children or prefer milder food, ask for dishes to be made less spicy, as the regional default leans hot.
Budget breakdown
A Somasila day trip is inexpensive if you are already in Nellore; the main cost is the car for the round trip to a place with limited public transport. The figures below are indicative planning estimates as of October 2026, not quoted fares, and assume two people sharing.
| Item | Estimate (per person) | Notes |
|---|---|---|
| Car hire, Nellore to Somasila return | ₹900 to ₹1,500 | Assumes two sharing a day taxi; varies by operator |
| Food and water | ₹200 to ₹400 | Packed lunch plus a meal in Nellore |
| Temple offering and small spends | ₹100 to ₹200 | Optional |
| Buffer | ₹200 | Parking, tips, incidentals |
| Rough total (day trip) | ₹1,400 to ₹2,300 | Excludes Nellore accommodation |
Add Nellore hotel costs from the stay section if you are making it an overnight trip. These are estimates to plan around; reconfirm all prices locally.
Permits and rules
No special permit is needed to travel to Somasila. It is an ordinary domestic destination in Nellore district, so Indian and foreign visitors do not require inner-line or protected-area permits to reach the area.
That said, the dam is a working irrigation structure. I could not find published visitor timings, an entry fee or official rules for the dam gallery or crest area, and access to such structures is often restricted on security and safety grounds. Confirm what is open with the Somasila Project office or local staff before approaching the dam itself, and do not photograph restricted installations if asked not to. Standard temple etiquette (modest dress, footwear removed) applies at the Someswara shrine.
Practical tips for Somasila
- Go early: mornings are cooler and the water reads best in soft light; the area is exposed with little shade.
- Carry essentials: water, snacks, sun protection and cash, since shops, ATMs and reliable UPI coverage near the dam are limited. Fuel up in Nellore.
- Mobile network: expect patchy coverage close to the reservoir; download maps offline before you leave Nellore.
- Medical and help: the nearest well-equipped hospitals are in Nellore city, so carry any personal medicines; there is little on-site assistance at the dam.
- Monsoon caution: during and after heavy rain the dam may release water and roads can be affected. Crest gates have been opened to discharge large flows in flood years, so avoid the riverbanks when releases are on and check local news first.
- Solo and women travellers: the dam is quiet and can be nearly deserted on weekdays; prefer a daytime visit, travel with a known driver, and tell someone your plan.
- Leave no trace: there is no organised waste collection at the water’s edge, so carry your litter back to Nellore.
Nearby places to combine with Somasila
Somasila pairs well with the temple towns and forts of Nellore district. Distances below are from the district administration’s places-of-interest listing where given.
| Place | Distance from Nellore | Why go |
|---|---|---|
| Jonnawada | About 12 km | Mallikarjuna Swamy and Kamakshi temple on the Pennar bank |
| Narasimhakonda | About 15 km | Hill shrine with views over the plains |
| Kandaleru Dam | About 60 km | Large linked reservoir in the Telugu Ganga system |
| Udayagiri Fort | About 100 km | Hilltop fort (about 3,079 ft), reached only by steps; temple ruins and a Sufi shrine |
| Penchalakona | Not stated | Narasimha shrine built around a large rock, one of the Nava Narasimha sites |
If you are extending into a longer Andhra Pradesh trip, Nellore’s good rail links make it easy to carry on north to the coast and the port city of Visakhapatnam, though that is a long haul of more than 600 km.
Frequently asked questions

Somasila is in Ananthasagaram mandal, Nellore district, Andhra Pradesh, on the Penna (Pennar) river. The Somasila Dam creates a large reservoir here, described by the district administration as the biggest irrigation project in the district. It lies about 80 km west of Nellore city (an indicative road distance), below the Eastern Ghats.
Is Somasila in Nellore the same as the Somasila with boat cruises?
No. The Somasila with organised pontoon and boat cruises is in Nagarkurnool district, Telangana, in the Srisailam backwaters of the Krishna river. This guide covers the Nellore Somasila on the Penna river, where I could not verify any official boat operator. Confirm which Somasila you mean before booking anything.
What is the best time to visit Somasila?
Late November to February is the most comfortable window, with cooler weather and a usually full reservoir. Incredible India rates October to March as pleasant for Nellore, but October carries peak rainfall of about 194 mm. Summers from March to June are hot and humid, with May reaching about 42 C, so avoid midday then.
How do I reach Somasila from Nellore?
Drive west from Nellore about 80 km (indicative) by hired car or taxi, as public transport to the dam is sparse. Nellore railway station is the nearest railhead on the Howrah to Chennai main line. The nearest airports are Tirupati (about 120 km) and Chennai (about 190 km), per the district administration.
Can you visit the Someswara temple at Somasila now?
The Sri Someswara Swamy temple beside the reservoir was damaged in 2021 flood releases and, according to the Deccan Chronicle, is being rebuilt at a cost of ₹13.50 crore, with completion expected around February 2027. The main sanctum survived. Because work may be ongoing, check locally whether the shrine is open before planning your visit around it.
Do I need a permit to visit Somasila?
No permit is needed to reach Somasila; it is an ordinary domestic site in Nellore district with no inner-line or protected-area rules. However, the dam is a working irrigation structure, so there may be access limits on the dam itself. Confirm what is open with the Somasila Project office or local staff, and follow any photography restrictions.
Last updated and sources
Somasila suits travellers who like quiet water and working-landscape India rather than built-up sightseeing, and it is at its best on a clear winter morning between late November and February. Pair it with a Nellore temple stop and keep plans flexible around the temple rebuild and the dam’s water releases.
